PC上面的蓝牙的通信（C#）

添加引用InTheHand.Net.Personal.dll

首先创建一个蓝牙类

 class LanYa {
 public string blueName { get; set; }                                   //l蓝牙名字
 public BluetoothAddress blueAddress { get; set; }               //蓝牙的唯一标识符
 public ClassOfDevice blueClassOfDevice { get; set; }            //蓝牙是何种类型
 public bool IsBlueAuth { get; set; }                                    //指定设备通过验证
 public bool IsBlueRemembered { get; set; }                        //记住设备
 public DateTime blueLastSeen { get; set; }
 public DateTime blueLastUsed { get; set; }
 }

然后就是搜索设备

 List<LanYa> lanYaList = new List<LanYa>();                //搜索到的蓝牙的集合
 BluetoothClient client = new BluetoothClient();
 BluetoothRadio radio = BluetoothRadio.PrimaryRadio;  //获取蓝牙适配器
 radio.Mode = RadioMode.Connectable;
 BluetoothDeviceInfo[] devices = client.DiscoverDevices();//搜索蓝牙  10秒钟
 foreach (var item in devices) {
 lanYaList.Add(new LanYa { blueName = item.DeviceName, blueAddress = item.DeviceAddress, blueClassOfDevice = item.ClassOfDevice, IsBlueAuth = item.Authenticated, IsBlueRemembered = item.Remembered, blueLastSeen = item.LastSeen, blueLastUsed = item.LastUsed });//把搜索到的蓝牙添加到集合中
 }

蓝牙的配对

 BluetoothClient blueclient = new BluetoothClient();
 Guid mGUID1 = BluetoothService.Handsfree;       //蓝牙服务的uuid

  blueclient.Connect(s.blueAddress, mGUID)      //开始配对  蓝牙4.0不需要setpin

客户端

 BluetoothClient bl = new BluetoothClient();//
 Guid mGUID2 = Guid.Parse("00001101-0000-1000-8000-00805F9B34FB");//蓝牙串口服务的uuiid

 try
 {
 bl.Connect(s.blue_address, mGUID);
 //"连接成功";
 }
 catch(Exception x)
 {
 //异常
 }

 var v = bl.GetStream();
 byte[] sendData = Encoding.Default.GetBytes(“人生苦短，我用python”);
 v.Write(sendData, , sendData.Length);              //发送

服务器端

 bluetoothListener = new BluetoothListener(mGUID2);
 bluetoothListener.Start();//开始监听

 bl = bluetoothListener.AcceptBluetoothClient();//接收

 while (true)
 {
 byte[] buffer = new byte[];
 Stream peerStream = bl.GetStream();

 peerStream.Read(buffer, , buffer.Length);

 string data= Encoding.UTF8.GetString(buffer).ToString().Replace("\0", "");//去掉后面的\0字节
 }

基本上就是这些吧！
