[android-developers] Re: getting exception while connecting to server via bluetooth
Also, be sure you are paired with the server or use createInsecureRfcommSocket
instead of createRfcommSocket.

[android-developers] Re: getting exception while connecting to server via bluetooth
Well, is your server listening on port one?
Port is to be between 1 and 30, and it may not be one if you specified
BT_PORT_ANY or a number other than 1 in your server.
This line says it is trying to connect on port one:
btSocket = (BluetoothSocket) m.invoke(device,Integer.valueOf(1));
