客户端实现蓝牙接收(C#)知识总结

在实现蓝牙接收时,网上的资料很多,使用起来也很简单,但是我觉得还是有必要把这些知识总结下来。蓝牙开发需要用到一个第三方的库InTheHand.Net.Personal.dll,其中关键的两个类是 BluetoothClient 和 BluetoothListener,首先开启一个子线程来不断的接收数据,使用很简单,直接上代码:
复制代码 代码如下:

using InTheHand.Net.Sockets;
using System.Threading;
   public MainWindow()
{
InitializeComponent();
     listenThread = new Thread(ReceiveData);
listenThread.Start();
}
private void ReceiveData()
   {
try
{
Guid mGUID = Guid.Parse("00001101-0000-1000-8000-00805F9B34FB");
bluetoothListener = new BluetoothListener(mGUID);
     bluetoothListener.Start();
      bluetoothClient = bluetoothListener.AcceptBluetoothClient();
     isConnected = true;
     }
     catch (Exception)
     {
       isConnected = false;   
     }
   while (isConnected)
    {
      string receive = string.Empty;
      if (bluetoothClient == null)
      {
         break;
      }
       try
      {
         peerStream = bluetoothClient.GetStream();
byte[] buffer = new byte[6];
        peerStream.Read(buffer, 0, 6);
         receive = Encoding.UTF8.GetString(buffer).ToString();
      }     
      catch (System.Exception)
      {
      }
      Thread.Sleep(100);
    }
}
BluetoothClient bluetoothClient;
BluetoothListener bluetoothListener;
Thread listenThread;
bool isConnected;

备注:发现用两个手机跟电脑配对成功后,两个手机同时连上PC端软件,一起发数据的话,PC端谁的也不接,暂时不下结论。
