蓝牙串行端口与 Obex 文件传输

Question

下午好。我正在开发一个应用程序，它可以通过蓝牙将文件从计算机传输到智能手机，但配对不符合我的预期。

与 32feets 库配对：

BluetoothEndPoint remoteEndPoint = new BluetoothEndPoint(selecteddevice.DeviceAddress,BluetoothService.ObexFileTransfer);

最后一个参数假定为蓝牙适配器 GUID。如果我用

喂它

BluetoothService.SerialPort。我只能连接到 Iphone SE
BluetoothService.ObexFileTransfer。我只能连接 Allview Soul Xtream Mini。我还有一个 galaxy tab 2，我无法通过任何一种方式连接它。我使用了一个 catch，错误如下：
- ex {"The requested address is not valid in its context 4CBCA5CAA8A0:0000110600001000800000805f9b34fb"} System.Net.Sockets.SocketException

我做了一些研究，这是我发现的： https://32feet.codeplex.com/wikipage?title=Errors

配对码：

private void Connect()
      {
           SelectBluetoothDeviceDialog bldialog = new SelectBluetoothDeviceDialog();
           serviceClass = BluetoothService.SerialPort;
           bldialog.ShowAuthenticated = true;
           bldialog.ShowRemembered = true;
           bldialog.ShowUnknown = true;

           if (bldialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
           {
                if (bldialog.SelectedDevice == null)
                {
                     System.Windows.Forms.MessageBox.Show("No device selected", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
                     return; 
                }                       
                BluetoothDeviceInfo selecteddevice = bldialog.SelectedDevice;
                BluetoothEndPoint remoteEndPoint = new BluetoothEndPoint(selecteddevice.DeviceAddress, BluetoothService.ObexFileTransfer);

                client = new BluetoothClient();
                try
                {
                     client.Connect(remoteEndPoint);
                }
                catch (SocketException ex)
                {
                     return;
                }
                catch (ObjectDisposedException ex)
                {
                     return;
                }
                catch (IOException ex)
                {
                     return;
                }

                textBox.Text += string.Format("Connected to: {0}", selecteddevice.DeviceName);
                textBox.Text += string.Format("Bluetooth Device Browser. Current Device: {0}", selecteddevice.DeviceName);

           }
      }

作为蓝牙，我使用的是 ASUS USB-BT400。 我该怎么做才能解决我的连接问题？

Answer 1

我这样解决了问题

       BluetoothDeviceInfo selecteddevice = bldialog.SelectedDevice;
                if (selecteddevice.DeviceName.ToLower().Contains("iphone"))
                     serviceClass = BluetoothService.SerialPort;
                else if (selecteddevice.DeviceName.ToLower().Contains("allview"))
                     serviceClass = new Guid("00001103-0000-1000-8000-00805f9b34fb");
                else serviceClass = BluetoothService.ObexFileTransfer;

此外，如果其他人知道我如何连接到我正在收听的 galaxy 选项卡，我也无法与之配对。
