Hi, Thanks for you answer.... This works when you make a server conexion.... but... When you create a client function works also the bind function? you see the function attachment to my first message. If I put a bind call in this function (client connect funcion) can i select the local bluetooth device?

Where can I select (in the example) what local module use? żżż??? Regards, Sir Graham.
