The bootloader will increment the nRF51822&#39;s MAC address by 1 if no peer data has been shared by the application, see <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/bledfu_appbonding.html?resultof=%22%62%6f%6e%64%22%20%22%73%68%61%72%69%6e%67%22%20%22%73%68%61%72%65%22%20">this</a> Infocenter page for more information.</p> <p>The simplest solution would probably be to modify the app so that it looks for both addresses, i.e. MAC and MAC+1.</p><div style="clear:both;"></div>
