Bluetooth question - Pleas help me!

Hi all,

I would like to do the following:

create a listener, which waits for a device to connect
when it is connected, start sending bytes

As far as I understood, I have to register a service to the Service Discovery Database, and thank I create an RSocket like this:

http://www.symbian.com/developer/techlib/v70sdocs/doc_source/devguides/cpp/bluetooth/UsingBluetoothSockets/Howtolisten.html#bt%2eguide%2esockets%2elisten

But how can I set the socket to use my service? How should my application now, if the other device connected to my service, or it want to connect to another bluetooth service?

I hope I was clear.

Thanks for your help in advance!

Best regards,
Balint Toth
