带有ConnectAsync的Windows Phone 8蓝牙错误 [英] Windows Phone 8 Bluetooth Error w/ ConnectAsync

问题描述

我正在尝试从Windows Phone连接到蓝牙设备。该设备已配对。该设备已知在Android手机上工作和测试。

I'm attempting to connect to a Bluetooth device from a Windows Phone. The device is already paired. The device is know to work and tested on an Android phone.

当目标设备是Windows Phone 8时调用ConnectAsync时出现以下错误：

When calling ConnectAsync when the target device is Windows Phone 8 I get the following error:

"无法执行对套接字的操作，因为系统缺少足够的缓冲区空间或因为队列已满。无法执行套接字上的操作，因为系统缺少足够的缓冲区空间或因为队列是
已满。"

"An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full."

  在System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification（任务任务）

  在System.Runtime.CompilerServices.TaskAwaiter.GetResult（）

   at System.Runtime.CompilerServices.TaskAwaiter.GetResult()
   at BluetoothTest.MainPage.<ConnectAppToDevice>d__1.MoveNext()

如果我使目标设备的Windows Phone 8.1我得到以下错误（无代码的修改）：

If I make the target device Windows Phone 8.1 I get the following error (no code modifications):

"找不到元素。 （HRESULT的例外情况：0x80070490）"

"Element not found. (Exception from HRESULT: 0x80070490)"
