5.3.2 - Description of the commands, and their formats
CMD NA ME DESCRIPTION
0x21 RES_SEND_FRAME
Response from the radio board to the frame emission
(response to the request 0x20, 0x22, 0x24, 0x26, 0x28,
0x2A)
0x26 REQ_SEND_POLLING Request to send a radio frame with the polling mode.
0x32 RECEIVED_FRAME_POLLING
Received radio frame following a REQ_SEND_POLLING
request
The format of the types of frame received by the host, are described as follow.
➢ Request in 'Polling' mode
REQ_SEND_FRA ME
HEADER CMD D ATA CRC ETX
3 bytes 1 byte variable 2 bytes 1 byte
0xFF ; 0x02 ;
0xXX
0x26
n bytes of data to transmit
the maximum size is 152 bytes
0x03
Remark : in radio polling mode, it is not necessary to transmit the address of the modules to be
interrogated, since they must be configured by the intermediary of the parameter POLLING_ROUTE.
➢ Acknowledgement of the request
