C＃Windows 10移动蓝牙BLE - OnAdvertisementReceived

Question

我试图学习如何在C＃中使用我的Windows 10移动智能手机来使用BLE。 我目前正在尝试连接我的Oral-B牙刷，以便从中获取数据。

不幸地在我的代码＆＃34; OnAdvertisementReceived＆＃34;永远不会被叫，我不知道为什么，牙刷是BLE启用的，并且在我的Android智能手机上使用分析器应用程序我可以看到它正在发送信标/广告以便连接，但我的调试文本 - 文本框没有变化。

这是我完整的C＃代码：

public sealed partial class MainPage : Page
{
    private BluetoothLEAdvertisementWatcher watcher;

    public MainPage()
    {
        this.InitializeComponent();

        // Create and initialize a new watcher instance.
        watcher = new BluetoothLEAdvertisementWatcher();
        watcher.SignalStrengthFilter.InRangeThresholdInDBm = -70;
        watcher.SignalStrengthFilter.OutOfRangeThresholdInDBm = -75;
        watcher.SignalStrengthFilter.OutOfRangeTimeout = TimeSpan.FromMilliseconds(2000);

        watcher.Received += OnAdvertisementReceived;

        watcher.Stopped += OnAdvertisementWatcherStopped;

        App.Current.Suspending += App_Suspending;

        App.Current.Resuming += App_Resuming;
    }

    private void App_Suspending(object sender, Windows.ApplicationModel.SuspendingEventArgs e)
    {
        watcher.Stop();
        watcher.Received -= OnAdvertisementReceived;
        watcher.Stopped -= OnAdvertisementWatcherStopped;

    }

    private void App_Resuming(object sender, object e)
    {
        watcher.Received += OnAdvertisementReceived;
        watcher.Stopped += OnAdvertisementWatcherStopped;
    }

    private async void OnAdvertisementReceived(BluetoothLEAdvertisementWatcher watcher, BluetoothLEAdvertisementReceivedEventArgs eventArgs)
    {
        textBox1.Text = "true";
        var address = eventArgs.BluetoothAddress;

        BluetoothLEDevice device = await BluetoothLEDevice.FromBluetoothAddressAsync(address);


        var cnt = device.GattServices.Count;

        watcher.Stop();
    }

    private void OnAdvertisementWatcherStopped(BluetoothLEAdvertisementWatcher watcher, BluetoothLEAdvertisementWatcherStoppedEventArgs eventArgs)
    {

    }

    private void button_Click(object sender, RoutedEventArgs e)
    {
        watcher.Start();
    }
}
