Core Location handles anything related to iBeacon and Core Bluetooth handles everything else but won&#39;t show iBeacon.</p> <p>On DFU what helps out is that they mod the mac id slightly so it advertises as mac id +1.&nbsp; At least it does in SDK11. A new mac id tricks the OS into thinking it is a new device.</p><div style="clear:both;"></div>
