you need to include the listen part, because this one gives you a socket
descriptor for the incoming connection in the end. From this descriptor
you can read() and write(). If you wanna accept only specific devices
then use getpeername() to get its address after they connected to you.
You can then decide what to do. If you don't like that device simple
close the connection.

The rctest.c is an example of how to do it. Don't include things that
you don't understand. For using RFCOMM it is enough to include the
bluetooth.h and rfcomm.h header files.

Regards

Marcel
