windows - 在 Windows 10 上连接到 BLE 外设

Question

我尝试连接到 BLE 外围设备。首先，我看广告:

watcher = new BluetoothLEAdvertisementWatcher { ScanningMode = BluetoothLEScanningMode.Active };
watcher.Received += WatcherOnReceived;
watcher.Start();

在 WatcherOnReceived 回调中我尝试创建 BluetoothLEDevice

public async void WatcherOnReceived(BluetoothLEAdvertisementWatcher sender, BluetoothLEAdvertisementReceivedEventArgs btAdv)
{
    BluetoothLEDevice bleDevice = await BluetoothLEDevice.FromBluetoothAddressAsync(btAdv.BluetoothAddress);
}

但是，我总是在 WatcherOnReceived 回调中得到 bleDevice == null。为什么以及如何解决它？在 UWP 应用程序中创建 BLE 设备的正确方法是什么？然后我需要连接到该设备，发现它的 GATT 服务和特征，启用其中一些的通知并读取/写入其中的一些。

这个问题的答案很简单——不要在 Windows 10 上使用 BLE。API 不起作用或行为随机，并且完全没有记录。我喜欢每个人都在谈论物联网是下一次工业革命，而微软在 BLE 存在 6 年后没有可用的 BLE API。
