I have been able to implement the PER test (on nRF51822) using the direct_test_mode_s110 and code based off the example python code from the nAN34 zip file. I adjusted to code to report the received packets and the calculated maximum packets. More than 50% of the time, the number of received packets is greater than the calculated max packets. Is there a more robust way to calculate or count the max packets? Should the max packets possible be the same as the number of packets transmitted in this case? I believe I could add to the dtm code to count and return the number of packets sent.
