So you need to use the connection handle to determine which device was disconnected. You can, for instance, by expanding the&nbsp;ble_nus_c_evt_t event structure to include the peer address, then update the peer address on <span>BLE_GAP_EVT_CONNECTED</span>.&nbsp;</p><div style="clear:both;"></div>
