https://devzone.nordicsemi.com/f/nordic-q-a/17669/how-to-make-permanently-unique-bluetooth-pairsI want to setup pairs of nRF51-dongle and nRF51-beacon where dongle-1 will always bond with beacon-1, dongle-2 with beacon-2, etc. If dongle-1 and beacon-2 are switched on while beacon-1 is still off, dongle-1 must not bond with beacon-2.

I think MAC address is the best to use for this, because you can never be sure that there won&#39;t be another company&#39;s beacons with the same name as yours.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/67969?ContentTypeID=1Fri, 11 Nov 2016 09:26:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c87d99fc-28cd-4ba6-ada7-d0654f202305Roger Clark<p>When you say bond to a beacon, do you mean bond to BLE device? I don&#39;t think you can connect to a beacon.</p> <p>Anyway, Assuming you want to connect to only one BLE device, you could add some custom manufacturer data to the &quot;beacon&quot; that contains a ID, then your &quot;Dongle&quot; can check the ID in the manufacturer data and only connect to the device that matches that ID number</p><div style="clear:both;"></div>
