The BLE application is event driven, so you should monitor the events to know which state the device is.</p> <p>When you receive wrong passkey from peer device you will get BLE_GAP_EVT_AUTH_STATUS event with p_ble_evt-&gt;evt.gap_evt.params.auth_status= BLE_GAP_SEC_STATUS_CONFIRM_VALUE</p><div style="clear:both;"></div>
