➢ Exchange with radio acknowledge
Configuration example of the parameters of wakeup management.
during an exchange between two WaveCard, where between two idle periods the transmitter must quickly
transmit data to the receiver.
1- Send a command of parameter modification to the receiver of the exchange, to modify its
WakeUp period to 0 (quasi-permanent reception) ;
2- Configure WakeUp_Length parameter of the transmitter with 40ms ;
3- transmit the data to the receiver ;
4- To send a command of parameter modification to the receiver of the exchange, to modify its
wakeup period to 10s (default value).
5- Configure WakeUp_Length parameter of the transmitter with 1100ms (default value).
3.2- Configuration of the control parameters
The parameters of control allow on the one hand, to modify the mode of radio communication, and serial
communication; and furthermore, fetch information on the local module, and the quality of the communication
with a distant module.
3.2.1 - selection of the radio operating channel when FHSS is deselected
It is possible to modify the transmission channel Reception via requests of reading, and writing. The
