https://devzone.nordicsemi.com/f/nordic-q-a/32011/how-to-measure-the-ber-bit-error-rate-of-the-ble-linkDear 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.en-USTelligent Community 13Wed, 14 Mar 2018 07:09:08 GMThttps://devzone.nordicsemi.com/thread/124277?ContentTypeID=1Wed, 14 Mar 2018 07:09:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e87d0d5a-b181-4857-a5a7-cb27a0e333ffxvhongpeng<p>thank u very much.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/124167?ContentTypeID=1Tue, 13 Mar 2018 13:07:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cc049868-072c-456a-af27-cec3cc40a8fdketiljo<p>You can&#39;t really see the packet loss of the BLE link. To to this, you&nbsp;can use <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.appnotes/dita/appnotes/pdflinks/nan_34.html?cp=10_2">DTM</a> and count lost packets. But this can&nbsp;only&nbsp;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.&nbsp;</p><div style="clear:both;"></div>
