pc是客户端，安卓是服务端。 pc端需要拖入一个 InTheHand.Net.Bluetooth.dll 文件放在Plugins文件夹里。dll文件下载链接 pc端参考资料 https://blog.csdn.net/oqzuser12345678923/article/details/51252545/ http://t.zoukankan.com/buptzym-p-2169858.html

安卓端使用是 NativeBT 插件，这个插件网上就可以下载

下面是pc客户端的代码

using UnityEngine; using System.Threading; using System; using System.IO; using InTheHand.Net.Sockets; using InTheHand.Net.Bluetooth; using InTheHand.Net; public class PC_BLT : MonoBehaviour { // 80:19:31:8C:6B:22 //F0:C8:14:33:8B:99 private Thread ReceiveThread; private BluetoothClient bluetoothClient = null; private Stream peerStream; public byte[] buffer = new byte[128]; //接收数据 private bool isConnecting = true; private BluetoothAddress sendAddress = new BluetoothAddress(new byte[] { 0x22, 0x6B, 0x8C, 0x31, 0x19, 0x80 }); //发送目的地址地址要反着写 // Start is called before the first frame update void Start() { BluetoothRadio bluetoothRadio = BluetoothRadio.Default; if (bluetoothRadio == null) { Debug.Log("没有找到本机蓝牙设备!"); } else { Debug.Log("ClassOfDevice: " + bluetoothRadio); Debug.Log("Name: " + bluetoothRadio.Name); Debug.Log(bluetoothRadio.LocalAddress); Debug.Log(bluetoothRadio.LmpSubversion); Guid guid = BluetoothService.Handsfree; Debug.Log(guid); } Console.ReadKey(); OpenPort(); } private void Update() { if (Input.GetKeyDown(KeyCode.Space)) { WriteMethod(); } } /// /// 打开端口 /// /// 端口名称 /// 成功否 public bool OpenPort() { BluetoothRadio.Default.Mode = RadioMode.Connectable; bluetoothClient = new BluetoothClient(); Guid mGUID = Guid.Parse("c1db6770-a359-11e6-80f5-76304dec7eb7"); // mGUID2 = Guid.Parse("00001101-0000-1000-8000-00805F9B34FB"); //bluetoothClient.Connect(sendAddress, mGUID2);//客户端对地址实现连接，这是一个阻塞线程，需要服务器端的回应 bluetoothClient.Connect(sendAddress, mGUID);//客户端对地址实现连接，这是一个阻塞线程，需要服务器端的回应 if (bluetoothClient.Connected) { Debug.Log("连接成功"); if (ReceiveThread != null && ReceiveThread.IsAlive) { ReceiveThread.Abort(); } ReceiveThread = new Thread(new ThreadStart(ReceiveMethod)); ReceiveThread.Start(); } else { Debug.Log("连接未成功"); } return true; } /// /// 接收数据 /// public void ReceiveMethod() { while (isConnecting) { try { peerStream = bluetoothClient.GetStream(); int a = peerStream.Read(buffer, 0, buffer.Length); } catch (Exception ex) { isConnecting = false; if (ReceiveThread != null && ReceiveThread.IsAlive) { ReceiveThread.Abort(); } Debug.Log(ex); } } } /// /// 发送数据 /// public void WriteMethod() { byte[] data = new byte[3] { 0x0A, 0x02, 0x03}; peerStream.Write(data,0 , data.Length); } public void OnDestroy() { if (ReceiveThread != null && ReceiveThread.IsAlive) { ReceiveThread.Abort(); } BluetoothRadio.Default.Mode = RadioMode.PowerOff; if (bluetoothClient != null && bluetoothClient.Connected) { bluetoothClient.Dispose(); bluetoothClient.Close(); } } }

下面是安卓服务端代码
