C# 如何连接到Gear S3上的蓝牙服务？

我正在为Gear S3编写一个web应用程序，并为C#中的UWP编写一个配套Win应用程序。 我想让它做的是：S3充当BT服务器，发送数据，Win应用程序充当客户端，接收数据。 在Tizen中，我使用了registerRfcommServiceByUUID（）函数，如下所示：

function publishTransferService() {

if(remoteDevice.isConnented){
    console.log("Connection Status: " + remoteDevice.isConnected);
    var TRANS_SERVICE_UUID = '5BCE9431-6C75-32AB-AFE0-2EC108A30860';
    adapter.registerRFCOMMServiceByUUID(TRANS_SERVICE_UUID, 'My Service', ServiceSuccessCb,
            function(e) {
        console.log( "Could not register service record, Error: " + e.message);
    });
}else{
    console.error("Connection Status: " + remoteDevice.isConnected);
    } 

在C#中，我尝试按如下方式连接到服务：

        //to ulong converted MAC-Address of the Gear
        ulong gearBtAddress = 145914022804881;
        //create device-instance of the gear
        BluetoothDevice gearDevice = await  BluetoothDevice.FromBluetoothAddressAsync(gearBtAddress);
        //list the services found on the gear and connect to the one with
        //the same uuid as in tizen
        var gearServices = await gearDevice.GetRfcommServicesAsync();
        foreach (var service in gearServices.Services)
        {
            if(service.ServiceId == RfcommServiceId.FromUuid(Guid.Parse("5BCE9431-6C75-32AB-AFE0-2EC108A30860")))
            {
                _service = await RfcommDeviceService.FromIdAsync(service.ToString());
            }

        }

我面临的问题是，C#无法找到想要的Uuid，尽管它可以找到其他几个Uuid。我不知道它在哪里丢了

提前谢谢。

我自己解决了，问题是UUID没有缓存。只需添加以下内容即可：

        var cacheMode = BluetoothCacheMode.Uncached;
        var gearServices = await gearDevice.GetRfcommServicesAsync(cacheMode);
