It seems the NRF_EVT_RADIO_CANCELED is more reasonable since if blocked there wouldn&#39;t be the previous advertisement but only the advertisement shortly after as you mentioned.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/22804?ContentTypeID=1Tue, 22 Sep 2015 03:44:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bcdfb6b3-3bec-4874-ab6b-6ee2502a066bjoc<p>For the second issue, I&#39;m not sure but guess may it be the spectrum leak of the physcial layer?
