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, 0, 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[100];
Stream peerStream = bl.GetStream();

peerStream.Read(buffer, 0, buffer.Length);

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

基本上就是这些吧！
