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().
