0x38 RECEIVED_BROADCAST_FRAME
Received a radio frame transmitted in a broadcast mode
b) Example of operations during a broadcast exchange, without waiting for responses
Reception of the END_MESSAGE_EXCHANGE command depends on the activation of the
EXCHANGE_STATUS parameter (0x0E). This command allows the equipment host to know exactly the
moment from which WaveCard is available for communication RS232.
5.4.3 - 'BroadCast' mode with waiting for responses
After transmitting a broadcast request, the WaveCard begins a reception phase during which it will memorize
all the responses. This phase stops on a timeout configured by BCST_RECEPTION_TIMEOUT parameter
(0x17). With each reception of response frame, the timeout is re-initialized.
After timeout, the WaveCard send the responses towards its host, via the serial link connection, frame after
frame.
a) Description of the commands
CMD NAME DESCRIPTION
0x21 RES_SEND_FRAME
Response from the radio board to the frame emission
(response to the request 0x20, 0x22,0x24, 0x26, 0x28, 0x2A )
0x24 REQ_SEND_BROADCAST_RESPONSE
Request to send a radio frame in response to a broadcast frame
0x28 REQ_SEND_BROADCAST
Request to send a radio frame in broadcast mode.
0x34 RECEIVED_BROADCAST_RESPONSE
Received radio frame following a REQ_SEND_BROADCAST request
0x37 END_MESSAGE_EXCHANGE
Frame indicating end of message exchange.This frame is returned only
after 0x22 & 0x24 & 0x2A Request command. Reception of this frame
is conditioned by the parameter EXCHANGE_STATUS value.
