Go to http://www.forrester.com/ for details on that report. Table of Contents

The goal of wireless LAN (802.11b) is to connect two relatively large devices that have lots of power at

This Introduction technology is also useful for network administrators who want to extend their LAN to places where it is Chapter 1 - Introducing Bluetooth to run cables. either expensive or inconvenient Chapter 2 - Bluetooth 1.1

802.11b can't be used to communicate to peripherals. 802.11b requires too much power for communication. 802.11b is overkill for small data transfers. 802.11b wasn't designed for voice communication. In the wireless communication arena, there is no technology that is best suited for every possible application. Either Bluetooth or 802.11b can be used for wireless communication between computers. Both have their place in the market and can perform in their niches well. Newer wireless LAN protocols like 802.11a and 802.11g will further clear the distinction between Bluetooth and wireless LAN because they extend 802.11b's bandwidth limitation to 54 Mb/s.

You canAimagine Bluetooth as functioning like any other protocol to connect to your peripherals, such as Appendix - javax.bluetooth serial (RS-232), parallel, USB, or Firewire. In the near future, your personal computer will be equipped Appendix B - javax.obex with a Bluetooth in the same manner that it currently features a serial and USB port. Appendix C - Java "port" Bluetooth Development on the PalmOS Platform Appendix D - BlipNet 1.1 API

You can use Bluetooth to connect to your peripherals wirelessly and effortlessly. Have you ever been to a remote location with a laptop and wanted to use a printer to print out some files? If you don't have the right List of Figures printer driver or the right cable, then you'll need to give your file to someone who does have it. If that List of Tables person doesn't have the right program to read your file, then you're out of luck; no printing for you. If you List of had aListings Bluetooth laptop and that printer was a Bluetooth printer (regardless of the manufacturer), then List of Sidebars you'd have no problem. With Bluetooth, you can ask the printer for the right driver if you don't have it, and then you can print your file with no problem. Index

The Power User So what if you're a power user? You most likely have a PDA, a wireless phone, a printer or two, a scanner, an MP3 player, a digital camera, and a DV camera. The back of your computer probably looks like a rat's nest of wires and cables. Some devices you may leave disconnected until you really, really need them. Bluetooth solves all this by allowing you to have virtually an unlimited number of peripherals wirelessly connected to your computer. The only limitation is that you can only have seven active connections at the same time. That should be fine because it would be quite rare for you to print, scan, upload pictures, and sync your PDA all at the same time.

Interoperability: Any Device to Any Device In the previous scenario, your non-Bluetooth-enabled devices are definitely not interoperable. In other words, if you want to send a picture from the camera to the PDA, then you'll need to use the computer to interconnect them. The same also goes if you want to scan a document and send it to the printer (i.e., to act like a copier) or send it to the PDA; you'll always need your PC to be the "man in the middle." Of course, you can buy a cable or two to do some of those tasks, but those cables are rare and expensive. Bluetooth solves all this by allowing your devices to communicate among themselves with no hassle and

with no cables. It's essentially the universal cable! Bluetooth for Java

So how12 do- the Bluetooth and the Bluetooth stack work together? What is their relationship? Well, a Chapter Bluetooth and device Jini Bluetooth without a stack can be compared to a computer without an operating system. More Appendix A device - javax.bluetooth specifically, it's like a computer peripheral without a driver. Figure 2-6 illustrates this concept.

Figure 2-6: A) The computer may be attached to its peripherals, but it can't control them without a driver. B) The computer may be attached to a Bluetooth device, but it can't control it without a stack. So, in order to communicate with the Bluetooth protocol and to control a Bluetooth radio, your computer uses a Bluetooth stack. Now, let's break down the Bluetooth stack into its individual components and see how they work. Each component of the stack is called a layer.

Layers of the Protocol Stack For application developers, the Bluetooth protocol can be broken up into two main items: layers and profiles. All the layers of the Bluetooth protocol form the protocol stack. Figure 2-7 shows how the following layers of the Bluetooth protocol "stack up": Host Controller Interface (HCI) Logical Link Control and Adaptation Protocol (L2CAP) Service Discovery Protocol (SDP)

Others like TCP/IP, OBEX, and WAP were not originated by subprotocols List Tables SIG, but they have been incorporated into the Bluetooth protocol. Those subprotocols are theofBluetooth List of Listings known as adopted protocols. List of Sidebars

Host Controller Interface (HCI) The Host Controller Interface is a layer of software that passes all your data from your computer to your attached Bluetooth device. For instance, if you are trying to communicate wirelessly from your PC (the host) and you have a Bluetooth device (the controller) attached to your USB port, then you'll need a layer that can understand the USB calls and send that information to the upper layers of the stack. Everything (voice and data) passes though the Host Controller Interface.

Logical Link Control and Adaptation Protocol (L2CAP) The Logical Link Control and Adaptation Protocol is the core layer of the stack through which all data must pass. L2CAP boasts some powerful features like packet segmentation and reassembling of data, as well as protocol multiplexing. If you are trying to pass a very large packet of data, L2CAP breaks up the packet and sends smaller ones. Conversely, L2CAP also reassembles segmented packets when accepting data. With protocol multiplexing, L2CAP can accept data from more than one upper protocol at the same time (like SDP and RFCOMM). Only data passes through the L2CAP layer; audio links have direct access to the Host Controller Interface.

Service Discovery Protocol (SDP)

A Bluetooth device uses Service Discovery Protocol in order to discover services. What's a Bluetooth Bluetooth for Java service? A good example would be a Bluetooth printer. A Bluetooth printer will publish itself with a ISBN:1590590783 by"IBruce Antony message such as, am aHopkins printer, and howRanjith can I help you?"

RFCOMM is commonly known as the wireless serial port, or the cable replacement protocol. The name is derived from the fact that your serial ports are called COMM1, COMM2, etc. RFCOMM simulates the Table of Contents functionality of a standard serial port. For instance, a Bluetooth-enabled PDA would use the RFCOMM Bluetooth for Java layer to synchronize its data to a Bluetooth-enabled PC as if they were physically connected by a cable.

Wireless Access Protocol (WAP)

Chapter 10 - Wireless Embedded Systems with the Micro BlueTarget Chapter 11 - Enterprise Bluetooth Applications with the Ericsson BlipNet

If you've used an Internet-enabled wireless phone before, then you've used WAP. In Bluetooth, this is an adopted protocol, so the Bluetooth SIG has incorporated the existing WAP protocol into the Bluetooth Appendix A - javax.bluetooth protocol to fit Bluetooth's needs. WAP requires that PPP, IP, and UDP be present in the stack. Chapter 12 - Bluetooth and Jini Appendix B - javax.obex

Appendix C - Java Bluetooth Development on the PalmOS Platform

Object Exchange (OBEX)

Appendix D - BlipNet 1.1 API Index

OBEX is a communication protocol initially defined by the Infrared Data Association (IrDA). Unless you've worked with infrared, you've probably haven't heard of OBEX. Just like WAP, OBEX was defined by List of Tables another group, but it was adopted by the Bluetooth SIG. OBEX is pretty useful when you want to transfer List of Listings objects like files between Bluetooth devices. OBEX does not require that TCP and IP be present in the List of Sidebars stack, but the manufacturer is free to implement OBEX over TCP/IP. List of Figures

Note A Bluetooth vendor does not need to implement all the Bluetooth protocol layers into its product in order to be Bluetooth compliant. For instance, a Bluetooth cordless phone may very well only have HCI, SDP, L2CAP, and TCS implemented into its stack. That's perfectly fine because a cordless phone may not need any extra functionality.

Bluetooth Network Encapsulation Protocol (BNEP) The Bluetooth Network Encapsulation Protocol is a layer in the Bluetooth stack that allows other networking protocols to be transmitted over Bluetooth, namely Ethernet. A Bluetooth vendor has many options if it wants to implement TCP/IP networking in its Bluetooth device. BNEP is a popular choice because it encapsulates TCP/IP packets in L2CAP packets before handing off the data to the L2CAP layer in the stack.

Human Interface Device Protocol (HID) The Human Interface Device Protocol is another adopted protocol in the Bluetooth specification. It was originally defined in the USB specification, and it lists the rules and guidelines for transmitting information to and from human interface devices like keyboards, mice, remote controls, and video game controllers. Table 2-3 is a handy guide that gives a brief description of the layers of the Bluetooth stack and their

That's why the Bluetooth SIG defined profiles. A Bluetooth profile is a designed set of functionality for Bluetooth devices. For instance, using the examples just listed, the phone and the PDA must both support Table of Contents the Synchronization Profile in order to synchronize data between themselves. In order to send object data Bluetooth for Java like a .vcf file from the PDA to the phone, both devices need to have the Object Push Profile implemented.

Distance Measuring The best wireless technology for accurately measuring distance is light waves and not radio signals. Light waves are direct, and the calculations can be pretty simple because the speed of light (in various mediums) is pretty well documented. Using radio signals to measure distance can be quite tricky, and one of the best ways to do that is to use triangulation, like GPS transceivers do. Whether you are using Java or C, Bluetooth might be a viable technology for triangulation, but definitely not for calculating or measuring accurate distances. Note The key word here is accurate. You can definitely use Bluetooth for proximity measurement (i.e., where in the building is Bruce Hopkins?). In fact, the Ericsson BlipNet does exactly that! See Chapter 11 for more information on the Ericsson BlipNet. So, to put it succinctly, you can only do what is possible using the constraints of the Bluetooth technology and what the JVM exposes to you. If the JVM only gives you access to the RFCOMM layer for communication, then you're stuck with it. If the OBEX layer is not exposed to the JVM, then don't expect to be able to send objects. To increase application portability, your Java Bluetooth vendor should implement the Java Bluetooth specification created through the JCP.

Bluetooth Java Bluetooth API The Benefits of theforJava by Bruce Hopkins and Ranjith Antony

ISBN:1590590783

There are two key advantages to using Apress © 2003 (352 pages) the official Java Bluetooth API versus a C-based (or native) API: The authors of this text describe how to develop wireless Java

API Is Independent of Stack and Radio Table of Contents

So what makes the official Java Bluetooth API better than a C/C++ Bluetooth API? One of the principle reasons is that the JSR-82 API is independent of the stack and the Bluetooth hardware. That gives you the Introduction ability to write applications without any knowledge of the underlying Bluetooth hardware or stack. And Chapter 1 - Introducing Bluetooth that's essentially what Java gives you today. If you write standard Java code (without any native methods), Chapter 2 - Bluetooth 1.1 you can run your code on basically any hardware platform and on any OS with little or no modification.

Because the JSR-82 is the official Java API for Bluetooth, all

vendors Awho implement the standard must include a core set of layers and profiles in their Bluetooth SDK. Appendix - javax.bluetooth Appendix B - javax.obex

A JSR-82-compliant Bluetooth stack must include the following layers:

These profiles are also required: Generic Access Profile Service Discovery Application Profile Serial Port Profile Generic Object Exchange Profile CROSSREFERENCE

See "The Bluetooth Protocol Stack" and "Profiles" in Chapter 2 for details on the Bluetooth protocol stack and profiles just in case you forgot.

The first thing that may come to your mind is, "Hey, wait a minute, doesn't the Bluetooth specification contain more profiles than that? Why did they implement only a few profiles in Java?" Well, here are two major reasons: First of all, the JSR-82 team wanted to get the Java Bluetooth specification in the hands of developers as quickly as possible. Recall in Chapter 2 that Bluetooth profiles are designed to be functional enough where higher profiles extend the functionality of the lower, or base, profiles. Refer to Figure 2-9, which shows a diagram of the relationship of the profiles of the Bluetooth specification.

Secondly, by implementing the base profiles (Generic Access Profile, Service Discovery Application Bluetooth for Java Profile, Serial Port Profile, and Generic Object Exchange Profile), the SDK vendor or the application ISBN:1590590783 Bruce Hopkins Ranjith Antony developer is free by to implement theand higher profiles of the Bluetooth specification.

Bluetooth Devices Chapter 2 - Bluetooth 1.1

Bluetooth devices were covered in Chapter 2, but just in case you forgot, take another look at Figures 2-1, - Understanding the Java Bluetooth API 2-2, and 2-3. Remember, Bluetooth devices are simply radios, so getting a single device is just like getting Chapter 5 - Bluetooth with J2ME MIDP a single walkie talkie; it's pretty useless. If your Bluetooth device is point-to-point capable, then that means Chapter 6 - Creating a Bluetooth Print Server with JPS API it can only talk to a single Bluetooth device at a time. If it is multipoint capable, then it can talk to up to Chapter 7 - Java OBEX seven devices atand a time. The Bluetooth device is also known as the controller. Chapter 4

Chapter 10 - Wireless Embedded Systems with the Micro BlueTarget Chapter 11 - Enterprise Bluetooth Applications with the Ericsson BlipNet The Bluetooth host is the computer that is physically connected to the Bluetooth device. For the most part, Chapter 12 Bluetooth and Jini this is your desktop PC, laptop, PDA, or smart phone. Usually, the connection is USB, RS-232, or UART. Appendix A - javax.bluetooth

List of Tables memory for the JVM. List of Listings List of Sidebars

Bluetooth Stack A Bluetooth stack is required in order for a Bluetooth host (the PC) to properly communicate to the Bluetooth device (the controller). If you go back to Figure 2-6, which shows a diagram of the Bluetooth stack, the bottom layer of the stack is the Host Controller Interface! See, it does make sense. The Host Controller Interface is literally the software required to interface the Bluetooth host and the Bluetooth device (the controller). Since this book is all about Java and Bluetooth, you might think that the Bluetooth stack needs to be written completely in the Java language. Well, not exactly. Some Bluetooth vendors have implemented a completely all-Java stack, while others have implemented a Java interface (i.e., JNI or other means) to a native stack. Either way, you need to access the stack through Java code, whether or not the stack is in Java.

Java Bluetooth API Finally, you're going to need a set of libraries to interface with your stack. For the most part, a company will sell you a Java Bluetooth API and Bluetooth stack together in a kit. Just be sure to ask them what Bluetooth devices their kit supports. Another question to ask your Java Bluetooth kit vendor is if their product is JSR-82 compliant. Currently, JSR-82 can only be implemented on the J2ME platform. JSR-82 cannot be implemented on the J2SE

platform because the J2SE does not support the Generic Connection Framework. Hopefully, the Generic Bluetooth for Java Connection Framework will be implemented by JDK 1.5. by Bruce Hopkins and Ranjith Antony

Appendix A -through javax.bluetooth Appendix B - javax.obex

The Bluetooth Control Center

Appendix C - Java Bluetooth Development on the PalmOS Platform Appendix D - BlipNet 1.1 API

The Bluetooth Control Center is an awkward beast due to its ambiguity. It is required to exist in a JSR-82 Index compliant implementation, but there are no guidelines in the official Java Bluetooth specification about how it List of Figures should be implemented. One vendor could implement the BCC as a set of Java classes, and another vendor List of Tables could implement it as a native application on the Bluetooth host. But no matter how it is implemented, it is an integral part of your security architecture because the BCC defines device-wide security settings for your List of Sidebars Bluetooth device. List of Listings

Now, for the most part, if you are working with a JSR-82-compliant Java Bluetooth development kit within your development environment, then the BCC will probably be implemented as one or more Java classes. But because the BCC is vendor specific, the classes that form the BCC will not have a javax.bluetooth package name; they will be in the form of something like com.vendor.bluetooth.bcc. Now, if you're working with a device that comes with the Java Bluetooth standard (like a mobile phone or a PDA), then there is a high probability that the BCC would be implemented as a native application on that device. According to the Java Bluetooth specification, these are the requirements of the BCC: Include base security settings of the device. Provide a list of Bluetooth devices that are already known. The devices do not need to be within range. Provide a list of Bluetooth devices that are already trusted. The devices do not need to be within range. Provide a mechanism to pair two devices trying to connect for the first time. Provide a mechanism to provide for authorization of connection requests. Information contained in the BCC must not be modified or altered other than by the BCC itself. Depending upon the JSR-82 implementation that you're using, the BCC may need to be packaged and deployed

with your application code.

Now before you can do anything, your stack needs to be initialized. Remember, a Bluetooth stack has direct applications using Bluetooth for a variety of platforms.

In some cases (in particular, with the Rococo Palm DK) no code is needed at all to initialize your stack. In other cases, you'll need to write a bit of code to get your stack initialized because you need to specify baud rates for your RS-232 interface.

So, that's about all it takes to perform device management with the Java Bluetooth APIs. Now, let's take a look at the concept in Bluetooth that allows you to discover other Bluetooth devices: device discovery.

Device Discovery Bluetooth for Java by Bruce Hopkins and Ranjith Antony

ISBN:1590590783

Your Bluetooth device has no idea of what other Bluetooth devices are in the area. Perhaps there are laptops, Apress © 2003 (352 pages) desktops, printers, mobile phones, or PDAs in the area. Who knows? The possibilities are endless. In order to The authors of this text describe how to develop wireless Java find out, your Bluetooth device will use the device discovery classes that are provided in the Java Bluetooth API to applications using Bluetooth for a variety of platforms. This see what's out there. includes an API overview of the Java library, development of Bluetooth-based services, highlights of security concerns, and

Which Bluetooth more. devices should use device discovery? Well, if you are planning to use a peer-to-peer application in Bluetooth, like two PDAs in a chat session, then either device would use device discovery to find the other device. If you are planning to use a client-server type application, like printing from a lap-top to a printer, then the Table clientofisContents most likely to perform device discovery. It doesn't make sense for the printer to constantly look for Bluetooth for Java devices that want to print something. Introduction

Now, let's a look atBluetooth the two classes needed in order for your Bluetooth device to discover remote Bluetooth Chapter 1 -take Introducing devices2in -the area: DiscoveryAgent and DiscoveryListener. Chapter Bluetooth 1.1 Chapter 3

When you to discover other Bluetooth devices in the area, DiscoveryAgent gives you two methods to Chapter 12 -want Bluetooth and Jini work with: and retrieveDevices(). Appendix A -startInquiry() javax.bluetooth Appendix B - javax.obex

public boolean startInquiry(int accessCode, DiscoveryListener listener)

Appendix C - Java Bluetooth Development on the PalmOS Platform

Appendix - BlipNet 1.1 API your DiscoveryAgent, you use this method to make your Bluetooth device search After youD have instantiated Index for other devices in the area. The length of the inquiry is totally dependent upon the implementation of the Java List Bluetooth of Figures specification. The accessCode can be one of the following DiscoveryAgent constants:

NOT_DISCOVERABLE, LIAC, or GIAC. You must also pass a reference to a class that implements the List of Tables DiscoveryListener interface. When new devices are discovered, event callbacks are passed back to this List of Listings object. This method will return trueif the device successfully went into discovery mode. The List of Sidebars startInquiry() method is the only way to perform device discovery without blocking the current thread. public RemoteDevice[] retrieveDevices(int option) Use the retrieveDevices() method to get a list of RemoteDevice objects that were found by previous inquiries. The option field has either the value of 0 for CACHEDor 1 for PREKNOWN. For your convenience, CACHED and PREKNOWN are also defined as constants in the DiscoveryAgent class. Unlike the startInquiry() method, this method blocks the calling thread until it returns. CACHED and PREKNOWN devices are determined by the BCC. Note For the most part, a CACHED device is simply a Blue-tooth device that was found from a recent inquiry. Of course, the definition of "recent" is implementation dependent. A PREKNOWN device is a level above aCACHED device and is one that you frequently communicate with. For example, let's say that you own a Bluetooth-enabled PDA. If you have exchanged business cards with another PDA within an hour, an implementation may classify that PDA as CACHED. However, if you own a printer at home, and you print to it often from the PDA, then an implementation may classify the printer as PREKNOWN. Please note that the retrieveDevices() method does not perform a true inquiry for Bluetooth devices, and subsequently, devices found from this method may not be in the area. However, this really isn't a problem, because the purpose of this method is to quickly give you the references to the devices that you want to connect to. The startInquiry() method will guarantee that the device is in the area, but it may take a considerable

amount of time in order to find the device that you want. Bluetooth for Java

Obviously, if the DeviceClass indicates that the major device class of the Appendix B - javax.obex RemoteDevice is a printer, then you're all set. But what if the major device class is a computer?

The service discovery-related classes in the Java Bluetooth specification implement the Service Discovery Application Profile. The Service Discovery Application Profile, in turn, uses the Service Discovery Protocol (SDP) List of Sidebars layer in your Bluetooth stack to find services on remote Bluetooth devices. List of Listings

CROSSREFERENCE

SeeChapter 2 for detailed descriptions of profiles and layers in Bluetooth.

The following classes are provided in the Java Bluetooth specification for service discovery: DiscoveryAgent, DiscoveryListener,ServiceRecord,DataElement, and UUID. You'll also interact (indirectly) with the SDDB whenever you want to discover services on a remote Bluetooth device.

The Service Discovery Database The Service Discovery Database (SDDB) is the central repository for all service records, but it's not a database in the sense of Oracle 9i, Sybase, or even MS Access. It's simply a collection of service records (and no, we don't mean a Java Collections object). The JSR-82 implementation is free to implement the SDDB in any form, so when a ServiceRecord object is stored in the SDDB, it doesn't necessarily mean that the JVM serialized the ServiceRecord object and stored it in a data store. If a particular JSR-82 implementation does not store service records in the SDDB as Java objects, then it must convert them into ServiceRecord objects when a client performs a search for services and a match is found. Figures 4-1 through 4-4 present graphical depictions of the SDDB, ServiceRecord,DataElement, and UUID objects in regard to how they all work together for service discovery.

If Chapter 7 - Java and OBEX you want to send a message to a Bluetooth server device, just perform service discovery with the UUID of Chapter 8 which - Using Bluetooth Simulator 0x0100, is athe UUID for L2CAP. If you have a Bluetooth-enabled PDA, and you want to send your Chapter 9 Bluetooth Security business card (.vcf) to other Bluetooth-enabled devices, then you'll perform service discovery with a UUID of Chapter 10 which - Wireless with the Micro 0x1105, is theEmbedded UUID for Systems the OBEX Object PushBlueTarget Profile.

For Chapter 12 Bluetooth and Jini instance, Headset and HeadsetAudioGateway are both distinct services that are a part of the Headset Profile. Therefore, service has its own UUID, 0x1108 and 0x1112, respectively. Some profiles, like the FAX Appendix A - each javax.bluetooth Profile, only have one service: FAX (which has a UUID of 0x1111).

Now, let's take a look at the constructors for UUID. public UUID(long uuidValue) This is pretty cut and dry—it constructs a UUID object from a long. public UUID(String uuidValue, boolean shortUUID) This method allows you to construct a UUID from a String representation of a UUID. If shortUUID is set to true, then a short UUID is returned (one that is made up of 16 bits instead of 128 bits). Note When using this method, be sure not to include the "0x" prefix in front of the String when constructing this object.

javax.bluetooth.DiscoveryAgent Hey, wait a minute, didn't we use this class for device discovery? Well, that's why the authors of the Java

Bluetooth specification named this class DiscoveryAgent, because they intended this class to be used for both Bluetooth for device and service discovery. InJava order to find services on remote devices, you'll use either selectService() or ISBN:1590590783 by Bruce Hopkins and Ranjith Antony searchServices(). Apress © 2003 (352 pages)

You must also provide Bluetooth an forobject Java that will implement the DiscoveryListener interface in order to receive event callbacks when services that match your UUID criteria are discovered.

Chapter 1 - Introducing Bluetooth Chapter - Bluetooth 1.1 public 2String selectService(UUID uuid, int security, boolean master) Chapter 3 - Before You Get Started

This method also allows you search for services, but it has a slight twist that makes it different from Chapter 4 - Understanding theto Java Bluetooth API searchServices(). This method Chapter 5 - Bluetooth with J2ME MIDPaccepts neither a DiscoveryListener nor a RemoteDevice object.

public void servicesDiscovered(int transID, ServiceRecord[] servRecord) If you use the DiscoveryAgent.searchServices() method (which accepts a DiscoveryListener), then this method is called by the JVM when services are discovered on the remote device. The transaction ID and an array of ServiceRecord objects are provided to this method. With a ServiceRecord in hand, you can do plenty of things, but you would most likely want to connect to the RemoteDevice where this ServiceRecord originated: String connectionURL = servRecord[i].getConnectionURL(0, false);

javax.bluetooth.ServiceRecord ServiceRecord objects are representations of individual entries in the SDDB. As you may remember, the SDDB is the central repository of service records for a Bluetooth device.

javax.bluetooth.DataElement As we continue to break down the anatomy of service discovery, let's now examine the DataElement object. EachServiceRecord object in the SDDB is made up of attributes. All attributes are stored as DataElement objects. A DataElement object can be from any of the following:

Okay, Bluetooth is a communication protocol, so how do you communicate with it? Well, the official Java Bluetooth API gives you three ways to send and receive data, but for right now we'll cover only two of them: Chapter 12 - Bluetooth and Jini RFCOMM and L2CAP. Chapter 11 - Enterprise Bluetooth Applications with the Ericsson BlipNet Appendix A - javax.bluetooth Appendix B - javax.obex

Note RFCOMM is the protocol layer that the Serial Port Profile uses in order to communicate, but these two items are almost always used synonymously.

List of Sidebars Sessions and Connections

Before we continue, there's a little more terminology to introduce here: sessions and connections. You can only have a single session between two Bluetooth devices. This limitation isn't a big deal, per se, because the definition of a session is simply one or more connections shared between two devices. You can also relate a Bluetooth session in the same way that sessions are created and used on the Web. When a Web server is communicating to a Web client, there is only one session, although there are numerous connections. Now, a Bluetooth device can have multiple sessions only if each session is linked to a different device. This also applies on the Web; powerful application servers have the capability to create multiple sessions and keep them in memory, but each session is linked to a different client. Server Connections with the Serial Port Profile Listing 4-5 demonstrates what is needed to open connections on a Bluetooth device that will act as a server.

For the most part, this is just about the same code used in service registration, and in fact, it is; service registration and server communication are both accomplished using the same lines of code. Here are a few Chapter 11 -need Enterprise Bluetooth Applications with url the Ericsson BlipNet items that to be pointed out. The String begins with btspp://localhost:, which is required if Chapter 12 Bluetooth and Jini you're going to use the Bluetooth Serial Port Profile. Next comes the UUID part of the URL, which is Appendix A - javax.bluetooth 00112233445566778899AABBCCDDEEFF. This is simply a custom UUID that was made up for this service; any Appendix B - javax.obex string that's 128 bits long could have been used. Finally, we have name=serialconn in the URL String.

The has also assigned a channel identifier to this service. The client must provide the channel List of implementation Sidebars number along with other parameters in order to connect to a server. Client Connections with the Serial Port Profile Establishing a connection with the Serial Port Profile for a J2ME client is simple because the paradigm hasn't changed. You simply call Connector.open(). StreamConnection con = (StreamConnection)Connector.open(url);

You obtain the url String that is needed to connect to the device from the ServiceRecord object that you get from service discovery. Here's a bit more code that will show you how a Serial Port Profile client makes a connection to a Serial Port Profile server: String connectionURL = serviceRecord.getConnectionURL(0, false); StreamConnection con = (StreamConnection)Connector.open(connectionURL);

What does a Serial Port Profile client connection URL look like? If the address of the server is 0001234567AB, then the String that the SPP client would use would look something like this:

L2CAP

Unlike RFCOMM connections, which are stream oriented, L2CAP connections are packet oriented. Before we cover to create L2CAP connections, we'll briefly cover a new concept called Maximum Transmission Unit Table ofhow Contents (MTU). We'll also cover the classes needed in order to create L2CAP connections: L2CAPConnection and Bluetooth for Java L2CAPConnectionNotifier. Introduction Chapter 1

Here's why we say "attempt": If the client indicates that it can Chapter - Bluetooth with J2ME MIDP receive6data in packet sizes of 10MB, and the server is only capable of sending data at 1kB, then there's no real Chapter - Creating a Bluetooth Print Server with JPS API problem; client'll get its data in 1kB packets.

List of Listings

L2CAPConnectionNotifier notifier = (L2CAPConnectionNotifier).Connector.open(url); List of Sidebars L2CAPConnection con = (L2CAPConnection)notifier.acceptAndOpen();

As you can see, it is not much different from the standard StreamConnectionNotifier and Connection used for RFCOMM server connections. L2CAP Client Connections Now here's the code that a client would use in order to establish an L2CAP connection with a server: L2CAPConnection = (L2CAPConnection)Connector.open(url);

Once again, it's pretty straightforward. More on MTUs Now, let's look at MTUs one more time, in conjunction with opening connections. For instance, if the server code looked like this: String url = "btl2cap://localhost:00112233445566778899AABBCCDDEEFF;ReceiveMTU=1024;TransmitMTU

=1024"; Bluetooth for Java by Bruce Hopkins and Ranjith Antony

ISBN:1590590783

The connection String Apress © for 2003the (352 client, pages)on the other hand, would look something like this: The authors of this text describe how to develop wireless Java using Bluetooth for a variety of platforms. This String url = applications "btl2cap://2E345BB78902:1055;ReceiveMTU=4096;TransmitMTU=512"; includes an API overview of the Java library, development of Bluetooth-based services, highlights of security concerns, and more.

As you can see, the server is proposing to send data in packet sizes of 1024 bytes. Since the client is able to receive data packets four times that size, the negotiated connection will have a packet data size of the lowest Table of Contents common denominator: 1024. On the other hand, the client wants to send its data in packets of 512 bytes. The Bluetooth Java server is for able to handle that packet size with no problem at all, and the negotiated connection will be 512 byte Introduction packets. Chapter 1

Now, let's take a brief look at the two classes used in order to create L2CAP connections and some of their Chapter 2 - Bluetooth 1.1 methods. Chapter 4 - Understanding the Java Bluetooth API javax.bluetooth.L2CAPConnection Chapter 5

public boolean ready(): This method will return true if there is any data ready to be read. If this method returns true, then a call to receive() will not block the main thread.

Appendix B - javax.obex

Appendix C - Java Bluetooth Development on the PalmOS Platform

Appendix D - BlipNet API public int 1.1 receive(byte[] inBuf): Regardless of the ReceiveMTU between your device and the Index remote device, you can set the size of inBuf to be whatever you want it to be. If the size of inBuf is greater List ofthan Figures or equal to the ReceiveMTU, then you won't lose any data during a transmission. If the size of inBuf[] List ofisTables smaller than the size of ReceiveMTU, then inBuf[] will be filled with data for the incoming packet, but List ofthe Listings remainder of the data will be lost. List of Sidebars

public void send(byte[] data): Use this method to send data to a remote Bluetooth device via the L2CAP protocol. You're free to send any size packet that you want, but if you exceed the TransmitMTU size, then the excess data will be discarded.

L2CAP vs. RFCOMM So now that you know how to send data between Bluetooth clients and servers using both L2CAP and RFCOMM, we bet you're wondering about typical usage scenarios for these connections. In other words, why would anyone use RFCOMM instead of L2CAP to send data or vice versa? Well, RFCOMM is also known as the virtual serial port communication protocol. An ideal way to use RFCOMM is in situations when you would replace a serial cable. For instance, if you were a developer for a GPS manufacturer, and your duty was to make one of their units Bluetooth enabled, then RFCOMM would be a likely choice in this scenario. Why? The GPS unit will always have a constant stream of information that needs to be processed, rendered, calculated, etc. So, collect the data from your stream and plot those coordinates on the screen. On the other hand, L2CAP is great for handling packet data. L2CAP can easily be used (and actually is) as a data multiplexer. You can read data from the connection, and based upon a header in the packet, you can route that data to different methods, threads, and classes in your application.

However, the MIDP 2.0 specification also brings along more functionality for wireless applications, including the following: Secure networking with HTTPS Push applications with the javax.microedition.io.PushRegistry class Standardized serial port communications Wireless application deployment with Over-the-Air provisioning (OTA) Better gaming applications with the javax.microedition.lcdui.game package

Developing MIDlets

What is a MIDlet? A MIDlet is a Java application that runs on a mobile device and uses the Mobile Bluetooth for Java Information Device Profile. MIDlets can be created by extending the ISBN:1590590783 by Bruce Hopkins and Ranjithclass. Antony javax.microedition.midlet.MIDlet A MIDlet has three states in its life cycle: active, Apress © 2003 (352 pages) paused, and destroyed. Those three states correspond to three methods:startApp(),pauseApp(), The authors this MIDlets text describe how to developin wireless anddestroyApp(). One or of more packaged together a JAR Java file constitute a MIDlet suite. applications using Bluetooth for a variety of platforms. This Software on the mobile device (called the application manager) is responsible for loading, running, and includes an API overview of the Java library, development of destroying the MIDlet. Bluetooth-based services, highlights of security concerns, and more.

Appendix C - Java Bluetooth Development on the PalmOS Platform Appendix D - BlipNet 1.1 API IndexNote Sun has created a very handy tool for MIDlet development called the J2ME Wireless Toolkit.

The tool comes bundled with an emulator and can package, compile, preverify, and run CLDC List of Figures and MIDP applications. The examples in this chapter use this tool, and it is available free from List of Tables the Wireless Java Web site (http://wireless.java.sun.com/). List of Listings List of Sidebars

Using the MIDP User Interface Components The MIDP UI is logically composed of two APIs: high-level and low-level. The high-level API is primarily designed for business applications, and it gives you objects like List,TextBox,ChoiceGroup, and DateField. This API includes a high level of abstraction because you can't define the visual appearance (i.e., shape, color, font, etc.) of those components. When using the high-level UI components, you won't have direct control of the navigation or scrolling, or have direct access to the input device (you can process input, but you won't have direct access to it). All of these items are handled by the MIDP implementation and are device dependent. This abstraction allows the same MIDlet to run on a Blackberry pager as well as on a Palm PDA. Thelow-level API, on the other hand, is designed for applications that need precise placement and control of graphic elements, as well as access to low-level input events. The low-level API is well suited for gaming or entertainment-based applications.

Using the RMS for Persistent Storage So, how do you store persistent data on a micro device? If you think about it, a mobile phone probably wouldn't have a file system in order to store its data. It's really overkill for such a small device that keeps names and phones numbers to have a file system just for data storage. Being aware of this, the J2ME architects have developed a viable alternative to storing data persistently called the RecordManagement System (RMS). The javax.microedition.rms package contains all the functionality that will enable

your classes to read, write, and sort data in the RMS. Bluetooth for Java

ISBN:1590590783 by Bruce Hopkins and Ranjith The RMS is a record-oriented database storedAntony in the nonvolatile memory of the mobile device. Since it is Apress © 2003 (352referred pages) record oriented, the RMS is also to as a flatfile system, where the data is stored in a series of rows in a table, much like theofdata in a conventional database.

Appendix B - javax.obex

Appendix C - Java Bluetooth Development on the PalmOS Platform

In order Dfor- J2ME to perform any networking or I/O, they must use the java.io and Appendix BlipNetapplications 1.1 API javax.microedition.io packages. These packages together form the Generic Connection Index Framework List of Figures(GFC). List of Tables

The general philosophy behind the GCF is to create a framework to abstract the communication process

List of Listings through a single class called Connector. You can then use Connector to create any connection like file List of SidebarsTCP/IP socket connections, HTTP connections, etc. In order to open a connection, just use I/O streams,

If a user wants to open an HTTP connection, the connection URL will look like this: Connector.open("http://mydomain.com");

Working with the Example Code Before you try out any of the examples in this book, it is recommended that you first get your JSR-82 implementation on your development environment installed and configured. If you don't have your development environment set up, then here's a checklist of the things that you need to do: Select a JSR-82 implementation that supports your OS. You can find an updated listing of JSR-82 implementations at the companion Web site for this book: http://www.javabluetooth.com.

Of course, you'll have to do more than just give the printer a document; you also need to tell the printer what exactly needs to be done to the document. Print attributes will indicate to the printer things such as List of Listings the size of the paper required, how many copies to print, the number of pages, and duplexing. The List of Sidebars packages javax.print.attribute and javax.print.attribute.standard allow you to create these attributes. List of Tables

Events The JPS event model is pretty simple; after you've submitted a print job to the printer, the printer will inform you of its status through events. You can be notified of things like the printer's on/off status, the number of pages printed, and so on. The javax.print.event package deals with creating and handling these events.

If you're new toYou theGet JPS, you may say to yourself, "I know what a printer is, but what's a print service?" Chapter 3 - Before Started In JPS, a javax.print.PrintService Chapter 4 - Understanding the Java Bluetooth APIobject is a logical representation of an actual printer. So instead of printingwith to aJ2ME printer, you'll print to a print service. Chapter 5 - Bluetooth MIDP Chapter 6

Identifying theSecurity Format - Bluetooth

Chapter 9

Chapter 10 - Wireless Embedded Systems with the Micro BlueTarget

The first thing to do is identify the data format. The class that allows you to do this is javax.print.DocFlavor. For instance, if you wanted to tell the print service that you want to print out Chapter 12 - Bluetooth and Jini GIF files, then the code would look something like this: Chapter 11 - Enterprise Bluetooth Applications with the Ericsson BlipNet Appendix A - javax.bluetooth Appendix B - javax.obex

DocFlavor docflavor = DocFlavor.INPUT_STREAM.GIF;

Appendix C - Java Bluetooth Development on the PalmOS Platform Appendix D - BlipNet 1.1 API

Index The JPS also has the functionality built in to print other popular binary formats like PDF, PostScript, PNG, List Figures andofJPEG. List of Tables List of Listings

Creating a Document

List of Sidebars

Now that you've specified a document format, the next step is to create a document. All documents in JPS must implement the javax.print.Doc interface. You can implement this interface yourself, or you can use the javax.print.SimpleDocobject to encapsulate your data into a document. Following is a snippet of code that demonstrates how to create a document from a GIF file: DocFlavor flavor = DocFlavor.INPUT_STREAM.GIF; FileInputStream fInput = new FileInputStream("nicePic.gif"); Doc doc = new SimpleDoc(fInput, flavor, null);

Searching for a Print Service Now it's time to find a suitable printer for your needs. In the JPS, you'll never interact directly with a printer; you will always have to interact with a print service that represents that printer. So, when you are searching for a printer (either connected peripherally to your computer, or somewhere on your network), you are searching for print services. The code that follows shows you how to search for a print service that can print GIF files. In addition, this example also demonstrates how to specify some print attributes; this print service is capable of printing two copies, double-sided, on A4 size paper.

DocFlavor flavor = DocFlavor.INPUT_STREAM.GIF; Bluetooth for Java PrintRequestAttributeSet attribSet = new HashPrintRequestAttributeSet(); ISBN:1590590783 by Bruce Hopkins and Ranjith Antony attribSet.add(new Copies(2)); Apress © 2003 (352 pages) attribSet.add(MediaSizeName.ISO_A4); The authors of this text describe how to develop wireless Java attribSet.add(Sides.TWO_SIDED_LONG_EDGE); applications using Bluetooth for a variety of platforms. This PrintService[] services = includes an API overview of the Java library, development of Bluetooth-based services, highlights of security concerns, and PrintServiceLookup.lookupPrintServices(flavor, attribSet); more.

As you can see, the static method lookupPrintServices() from the class javax.print.PrintServiceLookup returns an array of PrintService objects. Bluetooth for Java EachPrintService represents a printer that is capable of printing according to the attributes that you Introduction specified.

Bluetooth for Java What Is OBEX? by Bruce Hopkins and Ranjith Antony

ISBN:1590590783

OBEX (which stands for©OBject EXchange) is a communication protocol that allows object data to be Apress 2003 (352 pages) transferred between two devices (it doesn't matter if those devices are wirelessly or physically connected). The authors of this text describe how to develop wireless Java OBEX was originally created by the Infrared Data Association (IrDA), but it later became one of the applications using Bluetooth for a variety of platforms. This includes an API of theaJava development Bluetooth adopted protocols (likeoverview WAP). Take looklibrary, at Figure 7-1 to seeofwhere OBEX fits in the Bluetooth services, highlights of security concerns, and and IrDA protocolBluetooth-based stacks. more.

Note Did you realize that the official Java OBEX implementation was named javax.obex and not javax.bluetooth.obex? It was named javax.obex because the JSR-82 designers knew that (if structured correctly) the OBEX libraries would be the same regardless of the underlying transmission protocol (also known as the bearer or the transport). So, you can use the classes in thejavax.obex package to send objects between any device that implements the official Java OBEX API. The JSR-82 provides guidelines on how to use OBEX over Bluetooth, IR, and TCP/IP connections. The OBEX protocol has a simple client/server architecture. OBEX clients get objects from and put objects onto OBEX servers. OBEX servers wait around for incoming requests from clients. The OBEX definition can be summarized in two parts: the OBEX Object Model and the OBEX Session Protocol. The Object Model provides the definition of OBEX objects and information on how to transfer them. The Session Protocol defines the handshaking that needs to occur between the client and the server when transferring objects between devices. Let's look at OBEX Object Model and Session Protocol in more detail.

The OBEX Object Model In the OBEX Object Model, all the details about an object are represented as attributes called headers. Each header will contain information about the object (i.e., the name of the object) or the object itself. The Object Model defines headers as one byte for the header ID, and one or more bytes for the header's

value. A typical OBEX header is illustrated in Figure 7-2. Bluetooth for Java

The OBEX Object Model has defined 17 headers for OBEX object attributes. However, the official Java OBEX specification uses only 12 of them as constants in the interface java.obex.HeaderSet. These Table of Contents constants are listed in Table 7-1. Bluetooth for Java Introduction

Now that you have a pretty good understanding of the overall functionality of OBEX, let's take a look at the Java OBEX APIs.

You can obtain an instance of this interface Appendix A - an javax.bluetooth by usingBthe following line of code: Appendix - javax.obex Appendix C - Java Bluetooth Development on the PalmOS Platform Appendix ClientSession D - BlipNet 1.1 session API = (ClientSession)Connector.open(connectURL); Index List of Figures

List of Sidebars

Note See the description of javax.obex.Operation later in this section for more information on how to complete GET and PUT operations. The methods connect(),disconnect(), and setPath() complete their respective operations (CONNECT,DISCONNECT, and SETPATH) and return the result in a javax.obex.HeaderSet object.

javax.obex.HeaderSet TheHeaderSet interface can be used to define all OBEX headers (even custom headers). It can be instantiated by calling ClientSession.createHeaderSet(). An example of an OBEX client setting theNAME and TYPE headers is shown here: HeaderSet hdr = clientSession.createHeaderSet(); //Creating a header set to request Hello.txt file from the server hdr.setHeader(HeaderSet.TYPE," text/vCard"); hdr.setHeader(HeaderSet.NAME," Hello.txt");

An OBEX server, in turn, can retrieve the headers sent from the client by calling either getHeader() or getHeaderList().

Good question. Well, the OBEX SUCCESS response code is mapped to OBEX_HTTP_OK in the ResponseCodes class. And rather than simply having a generic response code for FAILURE, there are numerous response codes to indicate what kind of failure has occurred. Finally, the CONTINUE response will always be handled by your underlying implementation, so you should never see it. Here is an example of how to use the ResponseCodes class to determine if your PUT operation was a success:

javax.obex.SessionNotifier The SessionNotifier interface follows the same pattern as all notifiers in J2ME. A device that wants to be an OBEX server must implement this interface and call the acceptAndOpen() method and wait for clients, as shown in the following code: SessionNotifier sn = (SessionNotifier) Connector.open("btgoep://localhost:1106;name = FTP"); sn.acceptAndOpen(serverRequestHandler);

Once the server accepts a connection from a client, it then opens a channel for the client. The subclass of ServerRequestHandler that you passed to the acceptAndOpen() method is notified of all subsequent requests from the client. Now that we've covered many of the classes of the Java OBEX API, let's look at an example that puts

these concepts together.

We also gave a friendly name for this service, which is FTP. Our file transfer server has extended the ServerRequestHandler class, and has overridden the onConnect() and onGet() methods. Here, the onGet() method will attempt to read the requested file from the local storage and send the file back to the client. Obviously, the onConnect() and onGet() methods are only called if the clients send a CONNECT or GET operation to the server. The code for the file transfer server is shown in Listing 7-1.

More on Connection URLs and the SDDB

TheConnection URL and the service record attributes in the SDDB are closely related. Although software Bluetooth for Java developers may not care about the inner details of the SDDB, this information will be helpful when searching by remote Bruce Hopkins and for services on devices.

Now in order to access the File Transfer server, we must first perform device discovery and service discovery like we always do in Bluetooth applications. In addition to that, in our serviceSearchCompleted() method, we create our Operations and HeaderSets to instruct the OBEX server what we want to do.

The CONNECT Operation The first OBEX operation that needs to be created and sent to the OBEX server is CONNECT. This is accomplished by the following: con = (ClientSession)Connector.open(serviceURL); hdr = con.connect(hdr);

Theconnect() method of this ClientSession instance returns a HeaderSet object where we can inspect and determine if our CONNECT operation was a success.

The GET Operation Now that we have successfully performed our CONNECT operation, we are able to create other operations like GET,PUT, and SETPATH. The code that you would use in order to create and send a GET operation to an OBEX server looks like this:

Bluetooth for Java hdr = con.createHeaderSet(); ISBN:1590590783 by Bruce Hopkins and Ranjith Antony hdr.setHeader(HeaderSet.TYPE," text/plain"); Apress © 2003 (352 pages) hdr.setHeader(HeaderSet.NAME," Hello.txt"); authors of this text describe how to develop wireless Java Operation op The = con.get(hdr); applications using Bluetooth for a variety of platforms.

Difference Between a Simulator and an Emulator

List of Tables Is there a difference between a simulator and an emulator? Yes, definitely. An emulator is a

software program (or sometimes a hardware device) that emulates the functionality of another List of Listings computer system. Behind the scenes, the emulator translates the instructions of the device List of Sidebars being emulated to the machine code of the foreign system. Essentially, only computers can emulate other computers, and due to the translation process, emulation works best when a faster computer emulates a slower computer. Emulators are handy when you want to run a program, but the computing system for which it was originally designed no longer exists or isn't available. For instance, the Multiple Arcade Machine Emulator (MAME) project is a popular emulator that allows you to play classic arcade games on your desktop computer. PalmSource also makes an emulator that allows you to run different versions of the Palm OS on your desktop computer. This can be useful when testing to see if your code is backward compatible with older versions of the Palm OS. On the other hand, a simulator is something (usually software) that represents the functionality of an entire system. A simulator will mimic the interaction and communication process between devices in the system, and try to display the results as if those occurrences actually happened. For instance, an automotive company can create a crash test simulator. Using this simulator, the automotive engineer can simulate what would happen to the car if it collides with another object like a wall, a deer, or even another car. Now, in order for the simulator to be even remotely useful, formulas must exist that describe the interaction of the objects in the system. If such formulas do not exist, then a lot of mapping and modeling of the objects in the system need to be done ahead of time before the simulator is created. With the use of a Bluetooth network simulator, you can mimic the interaction of multiple Bluetooth devices on your desktop computer as if those occurrences were actually happening

Working with the Simulator Console The Simulator Console is the control panel to the Impronto Simulator. Using the Simulator Console, you can create and edit simulated Bluetooth devices. The characteristics of each device that you create are stored in an XML file in theconfig directory. For instance, to create a new Bluetooth device, just go to the File menu and select New Device as shown in Figure 8-3.

Figure 8-3: Creating a new Bluetooth device in the Simulator Console is pretty simple. The Impronto Simulator then gives you the option to set other properties for your simulated Bluetooth device such as the address, the connectable mode, the friendly name, and the device class.

Running an Application in the Simulator Okay, now that you've set up your environment, let's see what it takes to get your code running within the Impronto Simulator environment. In order to link your application code to the virtual Bluetooth devices that you've created, you need to specify an improntolocaldevice.friendlyname property for your application. In the J2SE, you can do this by executing the following line of code at runtime: java -Dimprontolocaldevice.friendlyname=TestPDA RemoteControl

That's of course assuming that the name of your application is RemoteControl and the friendly name of your virtual device is TestPDA. You can also specify this property within your Java class itself before calling any JSR-82 code:

System.setProperty("improntolocaldevice.friendlyname", "TestPDA"); Bluetooth for Java by Bruce Hopkins and Ranjith Antony

ISBN:1590590783

2003 (352 pages) If you're creating Apress a J2ME© MIDP application, you can set this property in your MIDlet's Java Application Descriptor (JAD) file. For example, the JAD filetext would contain the line: Java The authors of this describe how to following develop wireless

Bluetooth Security Measures

Introduction

Chapter 1 - Introducing Bluetooth Data security is an important aspect of any networked application. All data that is in transit is vulnerable to an attack Chapter - Bluetooth 1.1 from an2 eavesdropper (it doesn't matter if the connections are physical or wireless). Developers must realize that there Chapter 3 to - Before You Get Started is no way completely ensure that information transmitted wirelessly will only reach the intended destination. Chapter 4 - Understanding the Java Bluetooth API

Note exceptwith for infrared...but Chapter 5 Well, - Bluetooth J2ME MIDP of course, you already knew that! Chapter 6

- Creating a Bluetooth Print Server with JPS API

For application developers, the Bluetooth specification addresses security in three ways: authentication, authorization, - Java and OBEX and encryption. Let's look at these in more detail.

Chapter 7 Chapter 8

- Using a Bluetooth Simulator

Chapter 9

- Bluetooth Security

Authentication

Chapter 10 - Wireless Embedded Systems with the Micro BlueTarget Chapter 11 - Enterprise Bluetooth Applications with the Ericsson BlipNet

Authentication with Bluetooth consists of a simple challenge/response mechanism. The Bluetooth specification does not provide any means to authenticate users; you can only authenticate devices. So, the challenge/response does not Appendix - javax.bluetooth involve aAuser name and password as typical authentication schemes. Authentication with Bluetooth only involves a Appendix B - javax.obex number (PIN). personal identification Chapter 12 - Bluetooth and Jini

Appendix C - Java Bluetooth Development on the PalmOS Platform

During the Appendix D -authentication BlipNet 1.1 APIprocess, the PIN code is never transmitted from the client to the server. In order to authenticate, the client creates a 128-bit shared link key, which is derived from the PIN. If the PIN codes on the client Index andofthe server do not match, then the authentication process fails. List Figures List of Tables

A practical example for the usage of Bluetooth authentication would be a Bluetooth-enabled hotel business center. A hotel that's oriented to business travelers could enable authentication on all of its Bluetooth-enabled devices (like List of Sidebars printers and scanners) in the business center. Upon check-in, a registered guest of the hotel will be given the PIN code in order to access the services in the business center, and this would prevent non-hotel customers from simply walking up and using the services that are reserved for hotel guests. List of Listings

Server Authentication Bluetooth servers can request authentication by adding the authenticate parameter to the connection URL String. The code that follows shows a server using the Serial Port Profile, and requesting authentication: String url = "btspp://localhost:00112233445566778899AABBCCDDEEFF;authenticate=true"

If the authenticate parameter is set to true, then the JSR-82 implementation attempts to enforce authentication when devices connect to the server. Note The key word here is attempt. ABluetoothConnectionException will be thrown if the server does not support authentication, or if there is a conflict with the settings of the BCC. It is ultimately the decision of the BCC to allow authentication or to throw the exception. If the server device has a user interface, then the device may prompt the user to change the device's settings. If the authenticate parameter is set to false, then the implementation does not attempt to authenticate the client.

If the authenticate parameter is not in the URL String at all, then the implementation treats it as false, unless for Java you set encryptBluetooth or authorize to true.

String url = "btspp://02AB45AC35DF:00112233445566778899AABBCCDDEEFF;authenticate=true" Table of Contents Bluetooth If the authenticate for Java parameter is set to false (or is not in the URL at all), then the client will not require the server Introduction to authenticate. Chapter 1

- Introducing Bluetooth

Chapter 4

- Understanding the Java Bluetooth API

Note Why would the client request the server to authenticate it (especially if the server didn't require Chapter 2 - Bluetooth 1.1 authentication)?Well, since authentication is a requirement for encryption, the client may want to be Chapter 3 - Before You Get Started authenticated to the server in order to send some data securely, even though the server doesn't require it. Chapter 5 you're - Bluetooth with MIDP Whether a client or J2ME a server, you can request authentication even after the connection is established, as shown Chapter 6 Creating a Bluetooth Print Server with JPS API here: Chapter 7

- Java and OBEX

The JSR-82 API also gives you a method to check to see if your Connection to a RemoteDevice is authenticated. Just call the isAuthenticated() method of RemoteDevice.

Appendix B - javax.obex

Appendix C - Java Bluetooth Development on the PalmOS Platform

Appendix - BlipNet API that in both client and server authentication, the PIN is never specified in the URL (or NoteD Have you1.1 noticed Index anywhere else)? Assigning and entering the PINs on both the client and server are handled by the BCC. List of Figures List of Tables

Bluetooth Server Authorization

List of Listings

List of Sidebars Bluetooth servers can request that only authorized devices connect and use a particular service. These authorized

devices are called trusted devices. Servers can require that clients be authorized by setting the authorize parameter to true in the connection URL, as shown here: String url = "btspp://02AB45AC35DF:00112233445566778899AABBCCDDEEFF;authorize=true"

Authorization requires authentication, so the following line of code is more descriptive of what's actually going on: String url = "btspp://02AB45AC35DF:00112233445566778899AABBCCDDEEFF; authenticate=true;authorize=true"

However, if you explicitly set authenticate to false, and authorize to true, then the system will throw a BluetoothConnectionException. If authorization was not specified in the connection URL, the server can require the client to be authorized by calling the authorize() method of the RemoteDevice class as follows: // get an instance of the RemoteDevice if we don't already have it // assume that we have an active Connection object named "conn"

A good use of the authorization security measure occurs when you're dealing with personal devices. For instance, if you have a Bluetooth-enabled TV and a Bluetooth-enabled remote control, then you want your TV to only obey Introduction commands coming from your remote, obviously. Otherwise, you'll be vulnerable to common pranksters coming within Chapter 1 - Introducing Bluetooth range of your house, and changing your channels while you're watching TV—or even worse, turning on your TV at a Chapter 2 - Bluetooth 1.1 high volume at 3:00 a.m.!

Now, in11 order to encrypt information (whether you're using Bluetooth Chapter - Enterprise Bluetooth Applications with the Ericsson BlipNet or not), you need an encryption algorithm, an encryption and the information that you want to protect. An encryption algorithm (also called a cipher) is simply a Chapter 12 -key, Bluetooth and Jini

As we stated earlier, Bluetooth uses symmetrical encryption, so there's only one key for encrypting and decrypting information. However, the key is never transmitted from the server to the client. The encryption key is derived from several factors that are known to both the client and server (including the PIN). Now let's take a look at how to encrypt your data transmissions using the JSR-82.

Server Encryption Bluetooth servers can specify that they want their transmissions encrypted by setting the encrypt parameter to true in the connection URL, as follows:

String url = "btspp://02AB45AC35DF:00112233445566778899AABBCCDDEEFF;encrypt=true" Bluetooth for Java by Bruce Hopkins and Ranjith Antony Apress © 2003 (352 pages)

Client Encryption

Appendix A - javax.bluetooth Appendix B clients - javax.obex Bluetooth can also require that their communication with their servers be encrypted by setting the encrypt Appendix C -to Java Bluetooth Development on the PalmOS parameter true in the URL as demonstrated here: Platform Appendix D - BlipNet 1.1 API Index String url = "btspp://02AB45AC35DF:00112233445566778899AABBCCDDEEFF;encrypt=true" List of Figures List of Tables

String url = "btspp://02AB45AC35DF:00112233445566778899AABBCCDDEEFF; authenticate=true;encrypt=true"

If the encrypt parameter is set to false (or is not in the URL at all) then the transmissions between the client and server are not encrypted. After the connection has been established, both the server and the client can check to see if the transmission is encrypted by calling the isEncrypted() method of the RemoteDevice class. If all of this sounds really complex to you, don't worry; the encryption/ decryption process is all done behind the scenes by your underlying JSR-82 implementation, so you don't have to worry about ciphers, keys, and other cryptographic elements.

Index The Micro BlueTarget is based upon the 32-bit RISC/DSP embedded micro-processor architecture from

Hyperstone List of FiguresAG (http://www.hyperstone.com). Smart Network Devices chose this architecture primarily because of its extremely low gate count (the CPU itself consists of only just 35,000 gates), which List of Tables equates to its low power consumption. In the future, this opens the door for the possibility of smaller form List of Listings factor solutions, even System-on-Chip (SoC) architectures. List of Sidebars The Bluetooth baseband controller is a BlueCore 01b from CSR (see Figure 2-2), which is interfaced through a standard 16550-compatible UART device. By using a dual UART module (the 16752 chip) in the device, one UART is still free for external serial communication. Note The Micro BlueTarget Starter Kit connects the available UART to the RS-232 port. This allows developers who don't have a lot of hardware experience to quickly utilize the Micro BlueTarget for external serial communication. Note As an option, the dual UART device can be substituted by one of the many PIC family microcontrollers. This will enable the Micro BlueTarget to externally communicate via other protocols such as SPI, I2C, and GPIO. Some PIC chips will even enable the Micro BlueTarget to have a CAN bus interface or perform A/D conversion.

3. Format the Micro BlueTarget's flash disk using the HYFLASH utility. 4. Create the necessary configuration files and transfer them to the Micro BlueTarget's flash disk. These steps are all explained in detail in the Micro BlueTarget Starter Kit documentation. After you compile and preverify your code, just FTP the corresponding class files for your application to the Micro BlueTarget and hit the reset button. If your app is specified in the JSTARTUP.INI file, then it will automatically start up; otherwise, just start your application manually using the HYMON utility. Note The HyNetOS is a multilanguage, multitasking embedded operating system that can run native C applications and Java apps at the same time. In order to resolve conflicting requests between native and Java applications that want to utilize the Bluetooth stack and radio, Smart Network Devices created a centralized entity called the Bluetooth Service. The Bluetooth Service in JSR-82 vernacular is called the Bluetooth Control Center (BCC). As mentioned in Chapter 4, the Bluetooth Control Center doesn't necessarily have to be a Java application, and in the case of the Micro BlueTarget, the Bluetooth Control Center is a native application. For the Micro BlueTarget, you can initialize and control the Bluetooth Control Center via configuration files.

The Wireless Network Access Point Let's say that you have a Bluetooth-enabled device like a PDA or laptop, and want to use it to access the Internet via a traditional LAN access point (refer to Figure 10-8). With the Micro BlueTarget, you're already halfway there, and no

L2CAPEcho Example L2CAPEcho is a very simple example that will demonstrate communication between two Micro BlueTarget devices. This is the first example involving two Micro BlueTarget devices, and this is the kind of example that you want to run just to make sure you can get two devices talking to each other. If this example doesn't work, then you need to troubleshoot your setup and configuration. So how does it work? Well, as shown in Figure 10-9, one board is offering an "echo service" to the public. The other board is the client that is using that service and is sending messages to the server.

Figure 10-9: The L2CAPEcho Service Since this example contains most of the foundational elements that were described previously in this book, we won't go into further explanation other than the fact that the client sends a message once per second to the server. The server reads the message from the InputStream and writes it back to the OutputStream, and the client gets the message back as an echo. Listing 10-1 shows the code for the L2CAPEchoServer.

Wireless System Monitor Example Chapter 8 - Using a Bluetooth Simulator In the Wireless System Monitor example, we're going to look at an industrial device that is in great need of wireless communication: the Programmable Logic Controller (PLC). PLCs are industrial control devices that programmatically Chapter 11 - Enterprise Bluetooth Applications with the Ericsson BlipNet control large machinery. They are widely used with manufacturing facilities to control relays, switches, motors, sensors, Chapter 12 - Bluetooth and Jini test chambers, assembly lines, robotic arms—the list goes on and on. Chapter 10 - Wireless Embedded Systems with the Micro BlueTarget

Appendix A - javax.bluetooth

Now a large manufacturing facility is very likely to have a considerable number of PLCs, each doing a particular task. Appendix B - javax.obex Now, if you want Bluetooth to monitorDevelopment the status ofon a particular PLC, you typically would have to walk over to the machine that Appendix C - Java the PalmOS Platform you wantDto inquire 1.1 about, Appendix - BlipNet API and hook up a portable computer to the PLC's RS-232 interface. You would then run some program on the computer that would read the data coming from the serial port of the PLC. Index List of Figures

This in itself can become a tedious process, especially if you're the guy who has to check the status on the PLCs. Sometimes, the hardest part of the job is trying to hook up the serial cable. We're not kidding here; in some industrial List of Listings the PLC may be located in a hard to reach area, and the communication ports may be even harder to environments, List of Sidebars reach. As you can see, PLCs make good candidates to be converted into fixed-wireless systems. List of Tables

As shown in Figure 10-10, with the addition of a Micro BlueTarget, a PLC can instantly become a fixed-wireless system. The Micro BlueTarget will read the data from the RS-232 interface and transmit the data wirelessly with the Serial Port Profile. All a status technician needs to do is to come within range of the PLC to gather the data.

Figure 10-10: Using the Micro BlueTarget to create a fixed-wireless system SPP2COMM.java is a dual-purpose application that you could run on a Micro BlueTarget in order to read the data from its serial port and transmit it wirelessly. When the Micro BlueTarget receives data coming in from its COMM port, it will go into "server mode" and create a Serial Port Profile server and pipe the data from the COMM port to its Serial Port Profile "port." This same code could also be run on a JSR-82-enabled client in order to collect the data from the Micro BlueTarget. Since the client isn't collecting data from its serial port, it will automatically go into "client mode" and create a Serial

Port Profile client. When the client receives data, it will try to pipe the data to its native serial port. The code for forListing Java 10-3. SPP2COMM.javaBluetooth is shown in by Bruce Hopkins and Ranjith Antony

Client Options Once you get data feeding the Micro BlueTarget and have SPP2COMM running on it, then you're all set from the server's point of view; you have created a fixed-wireless system. Now on the client side of things, you have a few options. Let's say that the vendor of the PLC makes a program to read and interpret the data from the PLC (when connected serially, of course). You really don't need to use the SPP2COMM in client mode at all; all you need to do is Bluetooth-enable your laptop and pair it with the Micro BlueTarget. The vendor's program will read the data from the PLC (via the Micro BlueTarget) through COMM7 or COMM8 (which are typical Serial Port Profile ports) instead of COMM1 or COMM2.

Now let's say that all the preceding conditions exist, but for some reason you can't Bluetooth-enable the laptop that will Bluetooth for Java read the data from the PLC. Don't worry, there's hope for you too! All you need to do is attach another Micro by non-Bluetooth-enabled Bruce Hopkins and Ranjith Antony BlueTarget to your laptop and run the ISBN:1590590783 SPP2COMM program. Since this Micro BlueTarget is not Apress © 2003 (352 pages) collecting data over its serial port, it will automatically run in client mode and look for a Serial Port Profile server.

applications with the Java language. With any vendor implementation of the JSR-82, you can create hundreds of client-server, peer-to-peer, cable replacement, and fixed-wireless Bluetooth applications. Table of Contents However, this API falls short when you need to create enterprise Bluetooth applications. So what's an Bluetooth for Java enterprise Bluetooth application? Well, here are the major qualifications of an enterprise Bluetooth Introduction application: Chapter 1

Chapter 2 - Bluetooth 1.1 more than just seven active connections Capability to handle Chapter 3 - Before You Get Started

A connection range greater than just 30 API or 300 ft Chapter 4 - Understanding the Java Bluetooth Chapter 5

Chapter 7 - Java OBEX groups of nodes A means forand managing Chapter 8 - Using a Bluetooth Simulator

A means for session management when clients move between nodes Chapter 9 - Bluetooth Security Chapter 10 - Wireless Embedded Systems with the Micro BlueTarget

Note Of course, Class 1 Bluetooth devices have a range of 300 ft, but you must realize that if the

Chapter 11 client - Enterprise Bluetooth Applications with themost Ericsson BlipNet is a Class 2 or Class 3 device (like mobile phones and PDAs), then it doesn't matter Chapter 12 if- the Bluetooth and Jini server is a Class 1 device (like some LAN access points). Appendix A - javax.bluetooth

The JSR-82 was not created to handle enterprise Bluetooth applications, and doesn't provide any way to Appendix B - javax.obex address Cthe problems thatDevelopment enterprise Bluetooth applications can solve. Appendix - Java Bluetooth on the PalmOS Platform Appendix D - BlipNet 1.1 API

Consider the locations where Bluetooth applications will be widely deployed, like shopping malls, airports, museums, office buildings, and grocery stores. At a mall, for instance, the scaling issue is very important. List of Figures It's not practical to create a Bluetooth-enabled information kiosk at a mall without being able to scale up to List of Tables handle more than just seven active connections. In order to accomplish this, your enterprise Bluetooth List of Listings will contain more than a single Bluetooth-enabled node. applications Index

List of Sidebars

Centralized communication is an important feature in enterprise Bluetooth applications because there's no way to implement group management or session management without it. For instance, in a Bluetoothenabled museum exhibit, there should be a way to activate or deactivate a group of nodes without disturbing the other nodes on the network. Session management comes into play in a Bluetooth-enabled retail location like a grocery store. Without session management, a customer may be offered the same ecoupon multiple times when passing by a different node in a grocery store. In an office building, providing wireless network access to Bluetooth-enabled clients is a common enterprise Bluetooth application. Session management in this scenario is also important so that clients can freely roam around the building without having to reauthenticate when they go in and out of range of different nodes. In order to create enterprise Bluetooth applications, you need more than just a single Bluetooth device and an API.

The core part of the BlipNet system is the BlipServer. The BlipServer itself is not Bluetooth enabled at all. It does, however, have a direct TCP/IP connection to each of the BlipNodes (which are Bluetooth enabled) List Sidebarsthem via Java RMI. In order to create your enterprise Bluetooth applications, you write J2SE andofcontrols classes that interface with the BlipNet API. Now, since you're writing J2SE code here, you may realize that there's nothing preventing you from accessing external resources on behalf of your Bluetooth-enabled clients. In fact, that's the whole point of it. Using the Ericsson BlipNet, external resources such as databases, LDAP directories, Web servers, and e-mail servers are all available at your client's disposal (as long as you can access them via a Java API). This is reflected in Figure 11-2. List of Listings

List ofService Listings Discovery Application Profile List of Sidebars

LAN Access Profile Object Push Profile Note The BlipNodes also conform to the WAP over Bluetooth interoperability requirements as defined in the Bluetooth specification. Your enterprise Bluetooth application will listen for events from the BlipNodes and act accordingly. For instance, let's say that you want to track where employees are in the building (assuming, of course, that they are wearing Bluetooth-enabled ID badges). When users come within range of a BlipNode, your application will listen to device-discovered events via the Generic Access Profile. The BlipNet system is sophisticated enough to let you know which BlipNode detected a user, so all you need to do is store that data in a database, and create another application to view the results. Now let's say that you're the manager of a hotel, and you want to allow your customers with Bluetoothenabled devices to send e-mails wirelessly from within the conference rooms. At these "e-mail stations," the BlipNodes will use the Object Push Profile to send clients the custom e-mail application (of course, this works well if the app is a JSR-82 application). Clients compose their e-mail using the custom application, and when they are ready to send the e-mail, they simply come within range of an e-mail station and push the e-mail OBEX object to the BlipNode. On the BlipServer, your enterprise Bluetooth application will be listening for an Object Push event, and will connect to an e-mail server to send the e-mail on behalf of the hotel guest.

This application starts off by calling the method initBlipServerConnection()in the constructor. In turn, initBlipServerConnection() obtains a BlipServerConnection object by calling the static method getConnection() from the BlipServer class. The parameters to this method include the user name and password that you've created, as well as the hostname of the BlipServer: BlipServer.getConnection("Tracking", "Tracy", "localhost");

Afterwards, a BlipServerEventFilter is created by calling the getEventFilter() method: BlipServerEventFilter blipServerEventFilter = getEventFilter(discoverBlipNodeGroup, terminalsToTrack);

Finally, we're going to add an event listener to the BlipServerConnectioninstance by calling its addEventListener() method.

Lookup Lookup is a Jini service that acts much like a directory. For instance, if a printer wants to provide printer services to a Jini federation, then it must register that service with a Lookup Service. Conversely, if you are participating in a Jini federation, and you want to print, you must check the Lookup Service to see if any printer services are available.

Bluetooth for Java How Jini Works by Bruce Hopkins and Ranjith Antony

ISBN:1590590783

So, let's first define a Jini© ServiceItem. A ServiceItem is comprised of a service object and some Apress 2003 (352 pages) attributes. The only real restriction on ServiceItem objects is wireless that theyJava be serializable. The authors of this text describe how to develop applications using Bluetooth for a variety of platforms.

The service can be pretty much anything and doesn't necessarily have anything to do with the device that hosts the provider.

Discovering a Lookup Service In order to get the ball rolling, the clients (Service Providers or Service Consumers) must discover a Lookup Service. Note A Jini federation can have more than one Lookup Service. Jini defines three discovery mechanisms: Multicast announcement from a Lookup Service Multicast request from a client Unicast request from a client A Lookup Service can use multicast announcements periodically to advertise its presence on the network. Interested clients, Service Providers or Service Consumers in particular, can use the information provided in an announcement to communicate with the Lookup Service. Clients use multicast requests to discover a Lookup Service. A Lookup Service receiving a request responds directly to that client. Once the address of a Lookup Service is known, a client sends a unicast

request directly to the Lookup Service. Bluetooth for Java

Note however that all the devices are physically connected by traditional TCP/IP connections, and the federation is not wireless (unless the TCP/IP network is WLAN). There are no special precautions that need to be taken care of, so this federation is formed in the usual manner. Any of the devices in the federation can be Bluetooth enabled, but it makes sense that either the Service Provider or the Service Consumer have Bluetooth capability so it can act as a bridge between the Jini federation and an outside Bluetooth piconet elsewhere.
