How to measure the BER (bit error rate) of the BLE link?

[xvhongpeng]

Dear friends,

                I am using the nRF 52832, s132. I want to know the BER (bit error rate) of the BLE link. How can i measure it? Further, to what extent do other radio interferences influence the BER? and how can i measure it?

                regards.

You can't really see the packet loss of the BLE link. To to this, you can use DTM and count lost packets. But this can only be done on one channel at the time. A BLE connection will keep changing frequency, so if you have some noise on one channel, the problem will soon go away.
