CMD NAME DESCRIPTION
0x20 REQ_SEND_FRAME Request to send a radio frame with the waiting for the radio response.
0x21 RES_SEND_FRAME
Response from the radio board to the frame emission (response to the
request 0x20, 0x22, 0x24, 0x26, 0x28, 0x2A)
0x30 RECEIVED_FRAME Received radio frame by the radio board.
0x31 RECEPTION_ERROR
Frame indicating error type detected at the issue of last exchange in
point to point or relaying mode.
0x35 RECEIVED_FRAME_RELAYED
Received relayed radio frame by the radio board .Reception of this
command is possible only if RELAY_ROUTE_STATUS (0x06) parameter is
set.
Data frame description is as follow :

Remark : maximum size definition
- Point to Point mode
:
Max = 152 bytes of data
- Relaying mode : Max = 152 – (2 + 6 x Number of repeaters)
=> 1 repeater : 144 bytes of data,
=> 2 repeaters : 138 bytes of data,
=> 3 repeaters : 132 bytes of data.
