➢ Frame RECEPTION_ERROR format
With this command, the local WaveCard informs its host that a problem appeared at the time of the radio
exchange.
This command is forwarded only on the serial link, between the wavecard and its host, it thus does not
require an address of recipient.
Note: The error messages are activated only if parameter EXCHANGE_STATUS is positioned with
0x01, or 0x03.
In this last case, status messages are also activated, but does not intervene in this mode, only at
the time of the sending of a message without waiting of answer (MESSAGE, and BROADCAST
mode).

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.
