4. AT commands for PER estimation

AT commands listed below are sent to emitter and receiver

4.1. Emitter :

ATZ Reset

AT+TCONF[=freq:pow:bw:sf:cr:lna:pa][=868000000:14:4:12:4/5:0:0:1:16:25000:2:3] for example. Sets/gets the config LoRa RF test.

AT+TTRRSI[=nb_packets_sent] Sets the number of packets to be sent for PER Tx LoRa test.

4.2. Receiver:

AT+Z Reset

AT+TCONF[=freq:pow:bw:sf:cr:lna:pa][=868000000:14:4:12:4/5:0:0:1:16:25000:2:3] for example. Sets/gets the config LoRa RF test.

AT+TXRRSI [=nb_packets_received] Sets the number of packets to be received for PER Tx LoRa test.
