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

1 class LanYa {
2 public string blueName { get; set; }                                   //l蓝牙名字
3 public BluetoothAddress blueAddress { get; set; }               //蓝牙的唯一标识符
4 public ClassOfDevice blueClassOfDevice { get; set; }            //蓝牙是何种类型
5 public bool IsBlueAuth { get; set; }                                    //指定设备通过验证
6 public bool IsBlueRemembered { get; set; }                        //记住设备
7 public DateTime blueLastSeen { get; set; }
8 public DateTime blueLastUsed { get; set; }
9 }

然后就是搜索设备

1 List<LanYa> lanYaList = new List<LanYa>();                //搜索到的蓝牙的集合
2 BluetoothClient client = new BluetoothClient();
3 BluetoothRadio radio = BluetoothRadio.PrimaryRadio;  //获取蓝牙适配器
4 radio.Mode = RadioMode.Connectable;
5 BluetoothDeviceInfo[] devices = client.DiscoverDevices();//搜索蓝牙  10秒钟
6 foreach (var item in devices) {
7 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
8 }

蓝牙的配对

1 BluetoothClient blueclient = new BluetoothClient();
2 Guid mGUID1 = BluetoothService.Handsfree;       //蓝牙服务的uuid
3
4  blueclient.Connect(s.blueAddress, mGUID)      //开始配对  蓝牙4.0不需要setpin

客户端

 1 BluetoothClient bl = new BluetoothClient();//
 2 Guid mGUID2 = Guid.Parse("00001101-0000-1000-8000-00805F9B34FB");//蓝牙串口服务的uuiid
 3
 4 try
 5 {
 6 bl.Connect(s.blue_address, mGUID);
 7 //"连接成功";
 8 }
 9 catch(Exception x)
10 {
11 //异常
12 }
13
14 var v = bl.GetStream();
15 byte[] sendData = Encoding.Default.GetBytes(“人生苦短，我用python”);
16 v.Write(sendData, 0, sendData.Length);              //发送

服务器端

 1 bluetoothListener = new BluetoothListener(mGUID2);
 2 bluetoothListener.Start();//开始监听
 3
 4 bl = bluetoothListener.AcceptBluetoothClient();//接收
 5
 6
 7 while (true)
 8 {
 9 byte[] buffer = new byte[100];
10 Stream peerStream = bl.GetStream();
11
12 peerStream.Read(buffer, 0, buffer.Length);
13
14 string data= Encoding.UTF8.GetString(buffer).ToString().Replace("\0", "");//去掉后面的\0字节
15 }

基本上就是这些吧！
