Note:
In the MESSAGE mode, the error frame intervene only between the transmitter, and the first
repeater. Even if the other repeaters return errors, the transmitting module does not await an answer, and
proceeds to another action.
In both cases, the procedure of sending an error frame depends on parameter RADIO_ACKNOWLEDGE:
If RADIO_ACKNOWLEDGE is active, and the transmitter does not receive a radio
acknowledgement, then the request is re-emitted three times, before sending the error frame.
If RADIO_ACKNOWLEDGE is inactive, then the error frame is sent after time-out
RADIO_USER_TIMEOUT.
