Rather it uses the <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/lib_ble_advertising.html">Advertising Module</a>, which has its own API for controlling the advertising. Therefore it may be necessary to put the advertising module in the correct state as well. Have you tried calling ble_advertising_start() with BLE_ADV_MODE_IDLE as the advertising_mode parameter?</p> <p>If you let me know what exact example you are using then I can have a closer look. Also, if you have modified the example, please provide the modified code.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
