JSR-82 Sample : Bluetooth Service Search

Bruse — Mon, 14 May 2007 02:16:25 +0000

In the last article we found how to search for other bluetooth devices. Here we look in to how search for a service on a particular bluetooth device.

The following code sample shows you how to use the DiscoveryAgent to search for an OBEX Push bluetooth service. It first searches for all available Bluetooth Devices, and prompts to select a device on which to search the OBEX Push Service.

For this sample to work, you need a JSR-82 Implmentation (Java Bluetooth Stack) like ElectricBlue or aveLink in the class path.

JSR-82 Sample : Device Discovery

Bruse — Thu, 26 Apr 2007 19:51:40 +0000

This article provides Java sample codes to search for Bluetooth devices using a JSR-82 API. If you are new to JSR-82, we recommend you to read the JSR-82 Basics tutorial to get a basic idea Java and Bluetooth.

JSR-82 provides the class DiscoveryAgent for performing Device Discovery and Service Discovery. The LocalDevice class provides a factory method ‘getDiscoveryAgent’ that returns a singleton instance of the DiscoveryAgent. This instance can then be used to discover other bluetooth devices and services.

The following code sample shows you how to use the DiscoveryAgent to discover other bluetooth devices. For this sample to work, you need a JSR-82 Implmentation (Java Bluetooth Stack) like ElectricBlue or aveLink in the classpath.

JSR-82 Initialization : LocalDevice

Mark — Sun, 08 Apr 2007 17:26:41 +0000

LocalDevice class can be considered as the basic entry point to the JSR-82 API. It is used to initialize the JSR-82 stack, and to control the local bluetooth settings. If you are new to JSR-82, check out the JSR-82 Basics tutorial before reading this. JSR 82 API can be broadly classified into the following sections.

a. LocalDevice Settings Manipulation
Device Discovery
Service Discovery
Service Registration
L2CAP
SPP
GOEP
BCC

Out of these sections ,the LocalDevice class provides the lowest level of access to the bluetooth stack. There is also another part that can more or less be counted among the lowest layers of JSR82 : the Bluetooth Control Center or the BCC. This part is implementation specific and has no standard APIs. Each vendor can expose their own required APIs which they think is appropriate for their JSR82 implementation. In this article we will look in to LocalDevice and how it can be used to manipulate the Local Bluetooth Device settings.

Simulating JABWT applications using JSR-82 Simulators

Bruse — Fri, 30 Mar 2007 16:17:56 +0000

Any one who is developing JSR-82 based application hopes for an easy JSR-82 simulator over which they can test their applications.Testing on actual devices can be very time consuming, and may not be feasible in every circumstances. JSR-82 simulators mimic the real Bluetooth environment, providing a way for the Java Bluetooth developers to test their JSR-82 based application effortlessly, without the need of the actual Bluetooth device.

The major JSR-82 simulators available today are Java Wireless Toolkit from Sun, BlueSim from JSRSoft and Impronto from Rococo. Java Wireless Toolkit is a simulator for a wide range of J2ME based API’s, and hence is the biggest to download, and the toughest to configure. It allows only J2ME based simulations, and is not platform independent. BlueSim and Impronto are both platform independent and supports J2SE and J2ME.

In this article we review BlueSim and list its important features, which any good JSR-82 simulators should provide. The features that BlueSim JSR-82 Simulator provides to a Java Bluetooth developer are given below. (more…)

JSR-82 Basics

Mark — Thu, 29 Mar 2007 03:02:19 +0000

This is the first part of the tutorial covering the basics of JSR-82.

What is JSR-82?

JSR-82 is a standard defined by the Java Community Process for providing a standard to develop Bluetooth applications in Java. It is an open and non-proprietary standard for developing Bluetooth applications. The JSR-82 API hides the complexity of the Bluetooth protocol stack, by exposing a simple set of Java API’s. The JSR-82 specific can be downloaded from here.

Pre-Requisites

To develop a Bluetooth application in Java using the JSR-82, you need to have the following

JSR-82 Compliant Bluetooth Stack.

You need a JSR-82 Implementation to successfully develop and test a Java Bluetooth application. You either need to have a simulated enviorment like the Sun Java Wireless Toolkit, or a real Java Bluetooth Stack like ElectricBlue or Avelink. The simulator allows you to test the Bluetooth application in a simulated environment, with no access to real bluetooth device.

As a Bluetooth Java developer which phone will you choose from the list of hundreds of available phones? There are many hundreds of phones to choose from, that comes with the Bluetooth and Java enabled on it. But for a Bluetooth Java developer, the most important requirement is the support of JSR-82 API.

Here we list the most popular 15 mobile phones that support the JSR-82 API, with the complete list of all the JSR’s that each phone supports.

Bluetooth Basics

What is Bluetooth?

Bluetooth is a wireless communications specification named after the 10th century Danish King Harald Blatland, or “Bluetooth”. King Harald united the separate kingdoms of Denmark and Norway. The Bluetooth specification is intended to “unite” separate personal computing devices such as laptops, PDAs, palmtops, cell phones and peripherals, like printers for example. In short, Bluetooth is wireless technology intended for short-range radio links to replace cables. Its primary features are voice and data capabilities, robustness, low complexity, low power and low cost.

How Bluetooth Works

In the world of Bluetooth wireless technology, there are no wires and virtually no limits. Bluetooth operates on a 2.4GHz band that’s available everywhere, so no license or subscription is necessary. Using adaptive frequency hopping (AFH), the signal “hops” to various frequencies to help ensure your signal is secure. Additionally, Bluetooth products use 128-bit encryption and a PIN code upon the first connection, giving you a secure connection every time.

Unlike other wireless technology, such as infrared, the devices you want to synchronize don’t have to be facing each other to make the connection. As long as two Bluetooth enabled devices are within a specified range of one another, the connection will be made. This means you can talk on a wireless headset with your mobile phone stashed in the other room, access data from your PC on your mobile phone, or wirelessly stream music from your iPod to your home stereo. The possibilities are truly endless!

Operating range for Bluetooth enabled devices depends on the class. Class 1 devices have a range of 100 meters (300 feet) and Class 2 devices have a range of 10 meters (30 feet). Class 2 devices are most commonly found in mobile devices.
