nRF Connect BLE app does not support scanning ADV_EXT_IND and AUX_ADV_IND?

Question

Hi, 
 I'm using the BLE app (ver 3.6.0) in nRF Connect for Desktop together with a PCA10056. 
 I'm scanning for a device that sends three ADV_EXT_IND, one on each channel 37..39, on 1M PHY followed by an AUX_ADV_IND on 2M PHY. I can see the traffic in a Sniffer so the device behaves as expected. But the BLE app does not discover the device. 
 Is this setup supported by the BLE app?

Hi, 
 The BLE app in nRF connect for desktop does not support advertisment extensions, but nRF connect on both iOS and Android should as long as it is run on a phone that supports this BT feature. I tested this today with a Samsung A21s and an iPhone 11 pro max 
 ble_app_uart modification to perform ext. advertising on 2M 
 static void advertising_init(void)
{
 uint32_t err_code;
 ble_advertising_init_t init;

 memset(&init, 0, sizeof(init));

 init.advdata.name_type = BLE_ADVDATA_FULL_NAME;
 init.advdata.include_appearance = false;
 init.advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_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_fast_enabled = true;
 init.config.ble_adv_fast_interval = APP_ADV_INTERVAL;
 init.config.ble_adv_fast_timeout = APP_ADV_DURATION;
 init.config.ble_adv_extended_enabled = true;
 init.config.ble_adv_primary_phy = BLE_GAP_PHY_1MBPS;
 init.config.ble_adv_secondary_phy = BLE_GAP_PHY_2MBPS;

 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);
}
