问题描述
您好,
我正在使用Visual Studio 2017下的UWP框架开发蓝牙应用程序。一切顺利,感谢Microsoft示例(C#SDK示例BluetoothLE写得很好) 。
I'm developping a Bluetooth app using UWP framework under Visual Studio 2017. Everything is going well thanks to Microsoft Example (C# SDK Example BluetoothLE well writen).
在我开发的第四天,行中的API BluetoothLEDevice.FromIdAsync:
During my fourth day of development, the API BluetoothLEDevice.FromIdAsync in the line:
bluetoothLeDevice = await BluetoothLEDevice.FromIdAsync(bleDeviceToConnect) .Id);
bluetoothLeDevice = await BluetoothLEDevice.FromIdAsync(bleDeviceToConnect.Id);
不再有效,在我的应用程序中都没有,在Microsoft的原始样本中我都没有使用它作为示例(我没有触及任何内容) 。
Is no longer working, Neither in my app, neither in the original sample from Microsoft I'm using as example (I don't touch anything on it).
我不明白,因为我没有改变任何东西(在我的项目属性中,我的计算机上没有任何Windows更新)。当我调用该函数时,它永远不会返回。
I don't understand as I changed nothing (in my project properties, neither any Windows update on my computer). When I call the function, it just never return.
你见过这个吗?关于如何解决问题的任何意见?
Have you seen this? Any input on how to solve it?
我完全陷入困境,因为我现在无法连接任何对象而无法继续...
I'm totaly stuck and can't go ahead as I can't connect at all any object now...
谢谢,
祝你好运

您可以尝试关闭蓝牙设备,然后在设备中再次开启设置app => Devices =>蓝牙&其他设备。如果您仍然遇到此问题,请分享您的设备类型和设备操作系统版本
,以帮助我在相同的情况下重现此问题。
You can try to turn off your Bluetooth device then turn on it again in your device Settings app => Devices => Bluetooth & other devices. If you still have this issue, please share your device type and device OS version to help me reproduce this issue on the same circumstances.
