https://devzone.nordicsemi.com/f/nordic-q-a/1687/maximum-centrals-in-ancsHi I am trying to overcome the problem that I have confronted, I have no buttons to delete bonds. So instead of deleteing this is what I did. I modified the bondmanager code as follows static uint32_t on_auth_status_from_new_central(ble_gap_evt_auth_status_ten-USTelligent Community 13Thu, 06 Mar 2014 13:10:22 GMThttps://devzone.nordicsemi.com/thread/7461?ContentTypeID=1Thu, 06 Mar 2014 13:10:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:71cf7cdb-3a9e-4178-81f7-023e7ae03408Ole Morten<p>In general we recommend avoiding changing the SDK files, so I&#39;d rather use the error returned to the application to call the masters_delete() function from there.</p> <p>The change you&#39;ve done here is a little scary, since there will be a disagreement between the in-RAM state and the flash-state of the bond manager, and if you get a power reset or similar after this, you may see strange behavior.</p> <p>Also, in an actual application it may create undesired behavior to just delete all bonds if you bond with a new device, but this will be very dependent on how your application is to behave, so I can&#39;t say anything for sure about that.</p><div style="clear:both;"></div>
