C＃32feet.Net：在单独的线程中处理两个蓝牙连接，给出SocketException

我正在使用32feet.Net库编写C＃控制台应用程序，该库创建两个线程来搜索并连接到不同的蓝牙设备，然后打开TCP套接字，以便可以通过网络连接将数据传递给设备。 我知道这种情况听起来很奇怪，但我被一位资深同事要求这样做。

我的代码似乎只在连接了一个设备时工作正常，尽管在向后和向前传递几条消息后，蓝牙连接有时会丢失。 但是，有时一旦第二个设备连接，我就会收到一个错误，说System.net.sockets.socketexception a connection attempt failed because the connected party did not properly respond ，有时代码只是退出而没有抛出任何exception。

我想知道造成这种情况的原因，我已经看到32feet.Net库可以支持多个连接。 我想知道我是否犯了一些错误，因为我是C# .Net ，甚至是Windows的新手，以前从未编写任何基于蓝牙的代码。

Program.cs中： 

 using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading; namespace BluetoothManager { class Program { static void Main(string[] args) { BTManager rover_btm = new BTManager(); BTManager base_btm = new BTManager(); base_btm.Port = 0xba5e; rover_btm.Port = 17825; base_btm.Name = "Base"; rover_btm.Name = "Rover"; base_btm.match = (args.Length >= 1 && args[0] != "") ? args[0] : "dev1"; rover_btm.match = (args.Length >= 2 && args[1] != "") ? args[1] : "dev2"; Console.WriteLine("Base Station match: " + base_btm.match); Console.WriteLine("Rover match: " + rover_btm.match); Thread Base = new Thread(new ThreadStart(base_btm.HandleThread)); Thread Rover = new Thread(new ThreadStart(rover_btm.HandleThread)); Base.Start(); Rover.Start(); Base.Join(); Rover.Join(); Console.Read(); } } }

BTManager.cs： 

 using System; using System.Collections.Generic; using System.Linq; using System.Text; using InTheHand.Net.Bluetooth; using InTheHand.Net.Ports; using InTheHand.Net.Sockets; using System.Threading; using System.Net; using System.Net.Sockets; using Microsoft.Win32; using System.IO; namespace BluetoothManager { class BTManager { private static BluetoothDeviceInfo[] peers; private BluetoothClient client; private bool _isConnected = false; private string _match; private const string defpin = "0000"; private TcpListener tcpListener; private int _port; private string _name = "Not Named"; public string Name { get { return _name; } set { _name = value; } } public int Port { get { return _port; } set { _port = value; } } public bool IsConnected { get { return _isConnected; } private set { _isConnected = value; } } public string match { get { return _match; } set { _match = value; } } public BTManager() { client = new BluetoothClient(); } public void HandleThread() { BluetoothDeviceInfo device; while (!this.findDevice(out device)) ; Console.WriteLine("About to pair"); int count = 0; int max = 5; while ((!(BluetoothSecurity.PairRequest(device.DeviceAddress, defpin))) && count  element.DeviceName == match); foreach (BluetoothDeviceInfo btdi in peers) { Console.WriteLine(btdi.DeviceName); } if (device == null) { Console.WriteLine(Name +": Not Found"); return false; } else { Console.WriteLine(Name +": Found"); return true; } } } }

我正在使用套接字与蓝牙设备进行通信。 断开连接时释放任何资源非常重要。
