modification is done with the same baudrate as the request).
By default, the serial link baudrate is of 9600 bauds (value = 0x00).
Parameter value 0x00 0x01 0x02 0x03 0x04
Baudrate 9600 baud 19200 baud 38400 baud 57600 baud 115200 baud
The modification commands of the baudrate, are as follows :
CMD NAME DE SCRIPTION
0x42 REQ_CHANGE_UART_BDRATE Request to update serial link Baudrate
0x43 RES_CHANGE_UART_BDRATE
Response from the radio board to the serial link baudrate update.
Serial Link Baudrate is updated once the exchange is ended
Remark : In the command byte coding, the Response frame type are taking the Request command byte value
with the LSB bit set to 1.
