It depends on what your application has told the stack to do. If you have initiated a connection, you will also need to cancel that: ble_gap_adv_stop() ble_gap_disc_cancel() ble_gap_conn_cancel() If any connections have already been established, then they will also cause radio activity. You can terminate connections with ble_gap_terminate().
