https://devzone.nordicsemi.com/f/nordic-q-a/68180/problem-re-bondingOur application is based on nRF5 SDK 17.0.2.

You can, however, choose to allow this by setting the .allow_repairing flag as I explained in this thread:&nbsp;<a href="https://devzone.nordicsemi.com/f/nordic-q-a/51274/bonding-doesn-t-work-after-deleting-bond-info-on-nrf-connect">https://devzone.nordicsemi.com/f/nordic-q-a/51274/bonding-doesn-t-work-after-deleting-bond-info-on-nrf-connect</a>&nbsp;</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
