How to scan extended adv packet?

Player777

I'm using the nRF52840 and the nRF5 SDK 17.1.0.

I can enable extended advertising with the following program,

static void advertising_init(void)
{
    uint32_t               err_code;
    ble_advertising_init_t init;

    memset(&init, 0, sizeof(init));

  uint8_t data_need_adv[200] = {0x26, 0x14, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10
                , 0x26, 0x14, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10
                , 0x26, 0x14, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10
                , 0x26, 0x14, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10
                , 0x26, 0x14, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10
                , 0x26, 0x14, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10

                , 0x26, 0x14, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10
                , 0x26, 0x14, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10

                , 0x26, 0x14, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10
                , 0x26, 0x14, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10
                , 0x26, 0x14, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10
                , 0x26, 0x14, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10
                , 0x26, 0x14, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10
                , 0x26, 0x14, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10
                , 0x26, 0x14, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10};
  
  ble_advdata_manuf_data_t my_advdata;
  my_advdata.company_identifier = 0x0059;
  my_advdata.data.p_data = data_need_adv;
  my_advdata.data.size = sizeof(data_need_adv) / sizeof(uint8_t);
  init.advdata.p_manuf_specific_data = &my_advdata;

    init.advdata.name_type          = BLE_ADVDATA_FULL_NAME;
    init.advdata.include_appearance = false;
    init.advdata.flags              = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;

    init.advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
    init.advdata.uuids_complete.p_uuids  = m_adv_uuids;

  init.config.ble_adv_extended_enabled  = true;
    init.config.ble_adv_fast_enabled  = true;
    init.config.ble_adv_fast_interval = APP_ADV_INTERVAL;
    init.config.ble_adv_fast_timeout  = APP_ADV_DURATION;
    init.evt_handler = on_adv_evt;

    err_code = ble_advertising_init(&m_advertising, &init);
    APP_ERROR_CHECK(err_code);

    ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG);
}

but my scanner is unable to scan the extended packets.

I have also made the following modifications, however it still doesn't work.

static void nrf_ble_scan_default_param_set(nrf_ble_scan_t * const p_scan_ctx)
{
    // Set the default parameters.
    p_scan_ctx->scan_params.active        = 0;
#if (NRF_SD_BLE_API_VERSION > 7)
    p_scan_ctx->scan_params.interval_us   = NRF_BLE_SCAN_SCAN_INTERVAL * UNIT_0_625_MS;
    p_scan_ctx->scan_params.window_us     = NRF_BLE_SCAN_SCAN_WINDOW * UNIT_0_625_MS;
#else
    p_scan_ctx->scan_params.interval      = NRF_BLE_SCAN_SCAN_INTERVAL;
    p_scan_ctx->scan_params.window        = NRF_BLE_SCAN_SCAN_WINDOW;
#endif // #if (NRF_SD_BLE_API_VERSION > 7)
    p_scan_ctx->scan_params.timeout       = NRF_BLE_SCAN_SCAN_DURATION;
    p_scan_ctx->scan_params.filter_policy = BLE_GAP_SCAN_FP_ACCEPT_ALL;
    p_scan_ctx->scan_params.scan_phys     = BLE_GAP_PHY_1MBPS;
		p_scan_ctx->scan_params.extended      = 1;
}

Are there any additional settings I need to configure on the scanning side?
