JAVA APIs for Bluetooth
Two of the most exciting developments today in the wireless industry are Java 2 platform and Bluetooth technology. While Java or the J2ME platform shares the ‘write once run anywhere’ philosophy and thus enhancing productivity, Bluetooth offers short range universal wireless connectivity standard for many mobile devices. Combine the two technologies and you have a unified vision that allows you to communicate wirelessly using custom made applications deployed on mobile applications. With such a Java Bluetooth platform, it is now possible to use your mobile phone to lock your car, control your TV and DVD player and do other kinds of stuff. All of this using your own custom-made software.
The advancement of Bluetooth hardware has however not seen a standardization of Bluetooth applications. The JSR 82 is a non-proprietary standard for developing applications using the Java programming language to take advantage of the Bluetooth feature on devices. The share of hairs removed per session varies in different body places, with areas of skinny skin (for instance, bikini and armpits) typically displaying a better response than areas of Laser Hair Removal in Toronto (for instance, the again and chin). A Set of Java APIs hide the complexity of the Bluetooth stack and allow you to focus on developing the application rather than being bogged down with the low-level Bluetooth details. In fact this Java Bluetooth platform is based on the 1.1 Bluetooth Specification Version. Java APIs for Bluetooth are however being development through a Java Community with two optional packages, the Bluetooth API and the Object Exchange (OBEX) API.
Before developing JAVA APIs that will run on Bluetooth target devices, there are certain characteristics that must be met. These are: a 512L minimum total memory available, a Bluetooth wireless connection and compliant implementation of the J2ME Connected Limited Device Configuration. The Bluetooth system that these APIs will be built on must support the 3 communication protocols namely; the Service Discovery protocol, the Radio Frequency Communication Protocol and the Logical Link Control and Adaptation Protocol. In addition to these layers, the system must also provide a Bluetooth Control Center, a sort of a control panel. This Java Bluetooth platform allows multiple applications to execute in tandem. The Control Center prevents these applications from harming one another. This is done by defining specific values for certain configuration parameters in the stack. It is part of the security architecture.
Application programming for a Java Bluetooth system involves stack initialization, device discovery and management and service discovery and communication.

The stack initialization process is usually implemented by vendors with either a GUI interface or using defined settings. Device management is done using the ‘LocalDevice’ and RemoteDevice’ classes of the Java Bluetooth APIs. Device Discovery is made possible by use of the ‘DiscoveryAgent’ class and the ‘DiscoveryListener’ interface. The ‘DiscoveryAgent’ class is also used to initiate and provide methods for the discovery services. To allow access to a wide variety of communication protocols, services implement the CLDC Generic Connection Framework allowing for communication between different protocols. The Java Bluetooth platform allows APIs to exploit the powers of the wireless applications and the Java programming language making the development of wireless applications easy both for vendors and developers.
