This command can only be used after receiving a broadcast frame
(RECEIVED_BROADCAST_FRAME = 0x38). Thus, the destination
radio address of this message can only be that of the module that
transmitted the initial broadcast frame.
Using this command in any other conditions could render Wavecard
unavailable for a few seconds.
