Bluetooth connections - btsppEcho

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).
