Xamarin Android，蓝牙连接不起作用

Question

I am trying to do a simple bluetooth connection Using Xamarin studio. My code builds sucessfully but raises a Java.IO.IOExeption When I try to connect the bluetooth.

This is a snippet from my code.

    BluetoothAdapter  BluetoothAdapter1 = BluetoothAdapter.DefaultAdapter;
    BluetoothSocket socket;
    BluetoothDevice device
    btnConnect.Click += async delegate {
            if (BluetoothAdapter1 == null)
            {
                AlertDialog1.SetMessage("Device Does not support bluetooth");

                AlertDialog1.Show();
            }


            if(!BluetoothAdapter1.IsEnabled)
            {
                AlertDialog1.SetMessage("Bluetooth is not enabled");
                AlertDialog1.Show();
            }

            else{

                device = (from bd in BluetoothAdapter1.BondedDevices where bd.Name == "GT-N8000" select bd).FirstOrDefault();

                if(device == null)
                {
                    AlertDialog1.SetMessage("Device Not Found \n Make sure you are paired to the bluetooth device");
                    AlertDialog1.Show();

                }

                else
                {
                    ParcelUuid[] list = device.GetUuids();
                    String MyUUID = list[0].ToString();



                    try 
                    {
                    socket = device.CreateRfcommSocketToServiceRecord(UUID.FromString(MyUUID));



                        socket.Connect();
                    btnConnect.Text = socket.RemoteDevice.Name;

                    socket.Close();
                }

                    catch (Exception e)
                    {
                        AlertDialog1.SetMessage(e.Message);
                        AlertDialog1.Show();
                    }


                }
            }

This is some of my Output from the log.

我通过在连接后不立即关闭插座来解决此问题。
