Example: Creating a client-server pair using RFCOMM
This example MIDlet shows you how to create a simple client-server pair using the Bluetooth RFCOMM protocol. In this example:
The user of the server can send a message to all clients connected to the server.
The user of the client can send a message to all clients connected to the server by simply sending a message to the server.
The server receives messages from any connected client, and "echoes" the received message back to all clients (including the original sender).

Prerequisites
You need the following to develop and test this MIDlet:
Series 40 3rd Edition or S60 3rd Edition FP2 SDK or newer
Series 40 3rd Edition or S60 2nd Edition FP2 device or newer
Note: The S60 3rd Edition FP1 SDK implementation of the Bluetooth API does not support Limited Inquiry Access Code (LIAC), because the Symbian Bluetooth stack does not support the operation. In addition, changing the discovery mode is not supported.
For instructions on how to set up the Java ME development environment, see section Setting up the development environment.
