hi,i compile the project usbd_ble_uart, i use pca10056 ,sdk is SDK 16.0 .when try to stop the ble stack in the project ,there will show a log :Fatal error . so if it is impossible to stop the sd in the usb project ?my code like this:

/** @brief Application main function. */
int main(void)
{
    ret_code_t ret;
    static const app_usbd_config_t usbd_config = {
        .ev_state_proc = usbd_user_ev_handler
    };
    // Initialize.
    log_init();
    timers_init();

    buttons_leds_init();

    app_usbd_serial_num_generate();

    ret = nrf_drv_clock_init();
    APP_ERROR_CHECK(ret);

    NRF_LOG_INFO("USBD BLE UART example started.");

    ret = app_usbd_init(&usbd_config);
    APP_ERROR_CHECK(ret);

    app_usbd_class_inst_t const * class_cdc_acm = app_usbd_cdc_acm_class_inst_get(&m_app_cdc_acm);
    ret = app_usbd_class_append(class_cdc_acm);
    APP_ERROR_CHECK(ret);

    ble_stack_init();
    gap_params_init();
    gatt_init();
    services_init();
    advertising_init();
    conn_params_init();

    // Start execution.
    advertising_start();



//try to stop the  stack
    sd_ble_gap_adv_stop(m_advertising.adv_handle);
    uint32_t err_code;
    err_code = ble_conn_params_stop();
	  NRF_LOG_INFO("err_code =%d",err_code);
    APP_ERROR_CHECK(err_code);

    err_code = nrf_sdh_disable_request();
    APP_ERROR_CHECK(err_code);
    ASSERT(!nrf_sdh_is_enabled());





    ret = app_usbd_power_events_enable();
    APP_ERROR_CHECK(ret);

    // Enter main loop.
    for (;;)
    {
        while (app_usbd_event_queue_process())
        {
            /* Nothing to do */
        }
        idle_state_handle();
    }
}

Thanks, I was not aware of that example. Totally helpful and resolved my issue.

Hi,

In SDK 15.0 we added a USB+BLE example. You can find the source code and the project file of the example in the following folder: <SDK_InstallFolder>\examples\peripheral\usbd_ble_uart

Please take a look at that example, to see how to combine USB and BLE/SoftDevice.

Let me know if you still have issues with this after looking at that example.

Side note: If you are working on SDK 15.0 and nRF52840 DK 1.0.0, then there is a bug you should be aware of. See this post.
