流套接字访问被拒绝 Windows Phone 8.1 蓝牙 [英] Stream Socket Access denied Windows Phone 8.1 Bluetooth
问题描述
我尝试使用 StreamSocket-Class 将蓝牙设备与我的 Windows Phone (8.1) 连接.
I try to connect a Bluetooth device with my Windows Phone (8.1) with the StreamSocket-Class.
现在每次我调用 socket.CallAsync(HostName, RemoteServiceName) 时都会收到 AccessDenied 错误.我在 AppManifest 中激活了接近传感器.
Now every time I call socket.CallAsync(HostName, RemoteServiceName) I get an AccessDenied Error. I activated the Proximity sensor in the AppManifest.
代码如下:
private async void ConnectToDevice()
{
if (_socket != null)
{
// Disposing the socket with close it and release all resources associated with the socket
_socket.Dispose();
}
try
{
_socket = new StreamSocket();
// Note: If either parameter is null or empty, the call will throw an exception
await _socket.ConnectAsync(_currentPeer.HostName, "{00001101-0000-1000-8000-00805f9b34fb}");
// If the connection was successful, the RemoteAddress field will be populated
MessageDialog md = new MessageDialog(_socket.Information.RemoteAddress.DisplayName);
await md.ShowAsync();
Start.IsEnabled = true;
}
catch (Exception ex)
{
MessageDialog md = new MessageDialog("Connection failed");
await md.ShowAsync();
_socket.Dispose();
_socket = null;
}
}
感谢您的帮助!

我遇到了同样的问题.但最后我在 http://www.codefest.at/post/2014/02/03/Bluetooth-in-Windows-81-Apps-nutzen.aspx
I had the same issue. But finally I've found a solution at http://www.codefest.at/post/2014/02/03/Bluetooth-in-Windows-81-Apps-nutzen.aspx
互联网(客户端和服务器)功能不起作用.为什么 MS 没有在 Visual Studio 的 GUI 中提供蓝牙功能,这对我来说是个谜.
The Internet (Client & Server) capability doesn't do the trick. It's a riddle to me why MS doesn't provide the bluetooth capability in the GUI of Visual Studio.
只需将以下 xml 添加到您的 appxmanifest 中:
Just add the following xml into your appxmanifest:
<Capabilities>
<m2:DeviceCapability Name="bluetooth.rfcomm">
<m2:Device Id="any">
<m2:Function Type="serviceId:00001101-0000-1000-8000-00805F9B34FB" />
</m2:Device>
</m2:DeviceCapability>
</Capabilities>
