CHAPTER 11
Using the Bluetooth and OBEX
APIs
The J2ME Wireless Toolkit emulator supports JSR 82, the Java APIs for Bluetooth. JSR 82 includes two independent APIs:
■The Bluetooth API provides an interface to Bluetooth wireless networking, including device discovery and data exchange.
■The OBEX API allows applications to use the Object Exchange (OBEX) protocol over Bluetooth or other communication channels.
This chapter describes how the J2ME Wireless Toolkit implements the Bluetooth and OBEX APIs.
11.1Bluetooth Simulation Environment
The J2ME Wireless Toolkit emulator allows you to develop and test application that use Bluetooth without having actual Bluetooth hardware. The toolkit simulates a Bluetooth environment for running emulators. Multiple emulator instances can discover each other and exchange data using the Bluetooth API.
For an example, see the documentation of BluetoothDemo in Appendix A, “Application Demonstrations.”
11.2OBEX Over Infrared
The J2ME Wireless Toolkit implements OBEX transfer over simulated Bluetooth and infrared connections. The simulated infrared connection follows the IrDA standard (see http://www.irda.org/). Simulated infrared transfers can take place between multiple running emulators.
