Question

UWP应用程序开发环境： 1.桌面 2.windows 10 Pro 3. vs2017 15.6 4.插入式无线网卡

当我使用wifi直接技术直接连接到Android系统时，连接不稳定 1.“hs”在通电或读取设备配置时遇到错误。这可能是由于硬件故障或连接不良造成的。（HRESULT异常：0x80070288） 2.找不到元素上述两个错误经常出现。请有经验的人帮助我们。谢谢。代码如下：

 private async void ConnectionDevice()
        {
            try
            {
                if (directDevice != null)
                {
                    directDevice.Dispose();
                    directDevice = null;
                }
                await Views.MainPage.mainPage.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>
                {
                    _deviceViewModel.Message = "设备连接中...";
                });
                //

                WiFiDirectConnectionParameters connectionParameters = new WiFiDirectConnectionParameters();
                connectionParameters.PreferenceOrderedConfigurationMethods.Add(WiFiDirectConfigurationMethod.PushButton);
                //connectionParameters.PreferredPairingProcedure = WiFiDirectPairingProcedure.GroupOwnerNegotiation;


                directDevice = await WiFiDirectDevice.FromIdAsync(_deviceViewModel.DeviceId);
                directDevice.ConnectionStatusChanged += DirectDevice_ConnectionStatusChanged;
                if (directDevice != null)
                {
                    var EndpointPairs = directDevice.GetConnectionEndpointPairs();
                    //创建SOCKET连接监听
                    StreamSocketListener socketListener = new StreamSocketListener();
                    await socketListener.BindEndpointAsync(EndpointPairs[0].LocalHostName, "9568");
                    //连接监听事件
                    socketListener.ConnectionReceived += SocketListener_ConnectionReceived;
                    await Views.MainPage.mainPage.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>
                    {
                        _deviceViewModel.Message = "设备连成功";
                    });
                }
            }
            catch (Exception ex)
            {
                await Views.MainPage.mainPage.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>
                {
                    _deviceViewModel.Message = ex.Message;
                });
                ConnectionDevice();
            }
        }

我不知道您是否解决了该问题，但我认为这些错误来自功能，请确保您具有以下功能：

<Capability Name="internetClient" />
 <Capability Name="internetClientServer" />
 <DeviceCapability Name="proximity" />

使用wifi直接在uwp下传输文件时是否存在连接错误？
