I have a little interrogation regarding the Bluetooth channel on which to connect when establishing a Serial connection. When I search for services on a remote device, the relevant attributes returns a number corresponding to the "channel" on which to contact the device, this argument is what you need to feed to the socket in order to send stuff. Does this number has anything to do with the COM port on which the service runs or is it something completely different that is just a number used internally by the BT stack ?
