C# Windows BluetoothLeAdvertisement不包含由Android设备广播的服务uuid

我正在尝试读取Android外围设备从Windows 10播放的

ServiceUUID

，如下所示：

private void OnAdvertisementReceived(BluetoothLEAdvertisementWatcher sender, BluetoothLEAdvertisementReceivedEventArgs advertisementArg)
{
    Debug.WriteLine(" serviceUuids for advertisement " + advertisementArg.Advertisement.ServiceUuids.Count);
    foreach(Guid guid in advertisementArg.Advertisement.ServiceUuids)
    {
        Debug.WriteLine("uuid is " + guid.ToString() + " address is " +advertisementArg.BluetoothAddress+ " name is "+ advertisementArg.Advertisement.LocalName);
    }
}

AdvertiseData.Builder dataBuilder = new AdvertiseData.Builder();
dataBuilder.addServiceData(new ParcelUuid(bluetoothUuid), advertiseData.getBytes());

但是，当从Android外围设备接收到广告时，

ServiceUuids

列表的大小始终为0

这很奇怪，因为服务数据正确地放置在广告的

BluetoothLeadVertisementData部分中：

IList<BluetoothLEAdvertisementDataSection> dataSection = advertisementArg.Advertisement.DataSections;

foreach (BluetoothLEAdvertisementDataSection ad in dataSection)
{
    if (ad.Data.Length > 0)
    {
        DataReader dataReader = DataReader.FromBuffer(ad.Data);
        byte[] bytes = new byte[ad.Data.Length];

        dataReader.ReadBytes(bytes);

        if (bytes.Length > 0)
        {
            string data = System.Text.Encoding.UTF8.GetString(crcBytes, 0, crcBytes.Length);
            Debug.WriteLine("ANDROID DEVICE FOUND " + data);
        }         
    }
}

Android数据是“服务数据”部分类型，而不是“服务UUID列表”部分类型。服务UUID属性仅适用于服务UUID列表，而不适用于服务数据

由于蓝牙广告（信标）可用于发送包含通用唯一标识符（UUID）的信息包，数据包的数据部分可由应用程序开发人员自定义

我们应该能够解析BluetoothLEManufacturerData中的数据以获得UUID

例如：

private  void OnAdvertisementReceived(BluetoothLEAdvertisementWatcher watcher, BluetoothLEAdvertisementReceivedEventArgs eventArgs)
{
    var manufacturerSections = eventArgs.Advertisement.ManufacturerData;
    if (manufacturerSections.Count > 0)
    {
        var manufacturerData = manufacturerSections[0];
        var data = new byte[manufacturerData.Data.Length];
        using (var reader = DataReader.FromBuffer(manufacturerData.Data))
        {
            reader.ReadBytes(data);
        }
    }
}

有一个关于的官方示例，它显示了如何使用蓝牙广告API发送和接收蓝牙低能耗广告。
谢谢Jayden，但恐怕这不起作用。manufacturerSections的大小总是0我知道这有点晚，但据我所知，serviceData类型是一个单独的广告类型，而不是manufacturerData
