Bluetooth data transfer is handled using the RfcommSocket class, which provides a wrapper for the
Bluetooth radiofrequency communications (RFCOMM) protocol that supports RS232 serial communication
over an underlying Logical Link Control and Adaptation Protocol (L2CAP) layer.
In practice, this alphabet soup provides a mechanism for opening communication sockets between two
paired Bluetooth devices.
In order for an RFCOMM communication channel to be established, a listening port on one device must
be connected to an outgoing port on the other. As a result, for bidirectional communication, two socket
connections must be established.
