“await RfcommDeviceService.FromIdAsync（）"永远不会返回UWP应用程序 [英] "await RfcommDeviceService.FromIdAsync()" never returns in UWP app

问题描述

背景故事：

我创建了一个面向Raspberry Pi 3的UWP应用程序，它将通过BT连接到Arduino Uno。开发速度非常慢（但是如果你忽略了BT LE对/ unpair错误就行了）所以我决定切换到使用我的电脑连接到Arduino。问题
是，我无法连接到设备。它是配对的，在另一个平台上测试，但这不起作用。

I created a UWP app geared for the Raspberry Pi 3 that will connect to an Arduino Uno via BT. Development is very slow (but worked if you ignore the BT LE pair/unpair bug) so i decided to switch over to using my computer to connect to the Arduino. Problem is, is that I cannot connect to the device. it is paired, tested on another platform, but this doesnt work.

有问题的代码：

                    var device = devices.Single(x => x.Name == configuredDeviceName);
                    _service = await RfcommDeviceService.FromIdAsync(device.Id);
                    _socket = new StreamSocket();
                    await _socket.ConnectAsync(_service.ConnectionHostName, _service.ConnectionServiceName, SocketProtectionLevel.BluetoothEncryptionAllowNullAuthentication);
                    _dataReader = new DataReader(_socket.InputStream);

第2行永远不会回来。只是坐在那里...我的主机PC正在运行Windows 10（周年纪念版），树莓派正在运行win 10内幕预览（10.14393.67）。我可以添加更多代码，如果你需要看到它，但我整天都被困住了。

line 2 never comes back. just sits there... My host PC is running Windows 10 (Anniversary Edition) and the raspberry pi is running the win 10 insider preview (10.14393.67). I can add more code if you need to see it, but Ive been stumped all day.
