There is no further action required by the application, since the link is closed, typically the peripheral can now go to&nbsp;sleep&nbsp;after the BLE_GAP_EVT_DISCONNECTED event, until user press a button and start advertising again.</p> <p>The&nbsp;sd_ble_gap_disconnect() can be used for the peripheral to disconnect the link for instance if battery is low or the user is&nbsp;turning OFF&nbsp;the peripheral.</p><div style="clear:both;"></div>
