Is there any way to adjust the BLE advertisement scanning interval on Windows 10 when using Windows.Devices.Bluetooth.Advertisement.BluetoothLEAdvertisementWatcher

    for Windows Universal App try to change StartScanner as following:

    public static void StartScanner(int scanType, ushort scanInterval, ushort scanWindow) {

    Action action = (object obj) => {
        BLUETOOTH_FIND_RADIO_PARAM param = new BLUETOOTH_FIND_RADIO_PARAM();
        param.Initialize();
        IntPtr handle;
        BluetoothFindFirstRadio(ref param, out handle);
        uint outsize;
        LE_SCAN_REQUEST req = new LE_SCAN_REQUEST { 
            scanType = scanType, 
            scanInterval = scanInterval, 
            scanWindow = scanWindow 
        };
        DeviceIoControl(handle, 0x41118c, ref req, 8, IntPtr.Zero, 0, out outsize, IntPtr.Zero);
    };
    Task task = new Task(action,"nothing");
    task.Start();
}
