Using Thread Radio test for PER measurements
You can perform a Packet Error Rate (PER) measurement using the Radio test application running on two nRF7002 Development Kit (DK) or Evaluation Kit (EK) devices, where one is used as a transmitter and the other as a receiver.
Configure the receiving device (DK or EK) to receive packets with a known access address at a center frequency of 2400 MHz.
uart:~$ data_rate ieee802154_250Kbit
uart:~$ start_channel 18
uart:~$ parameters_print
uart:~$ start_rx
Configure the transmitting device (DK or EK) to transmit 10000 packets (TX transmit count) with the matching access address at center channel 18.
uart:~$ data_rate ieee802154_250Kbit
uart:~$ start_channel 18
uart:~$ parameters_print
uart:~$ start_tx_modulated_carrier 10000
Record the number of successfully received packets on the receiving device (DK or EK).
Repeat as necessary until the count stops incrementing.
RX success count is the final item in the print display: Number of packets.
uart:~$ print_rx
Terminate receiving on the transmitting device (DK or EK).
uart:~$ cancel
Calculate PER using the following equation:
