实现蓝牙vs安卓开发

      android实现蓝牙开发的资料不是很多，在安卓开发中，如何实现蓝牙通信呢？一般的方法是通过蓝牙的虚拟串口，然后经过一系列的配置完成简单的实现，外置蓝牙的通讯也是用这种方法来做的！但是我们在进行android开发的时候这种方法是不支持的，所以我就来演示一下关于蓝牙安卓软件开用发第三方.NET组件（inthehand）来将其实现。

接下来我们初始化核心代码，作为客户端的pc机它需要通过手机蓝牙MAC地址实现通信！

/// <summary>
        /// 打开端口
        /// </summary>
        /// <param name="Name">端口名称</param>
        /// <returns>成功否</returns>
        public bool OpenPort(string Name)
        {

            InTheHand.Net.Bluetooth.BluetoothRadio.PrimaryRadio.Mode = InTheHand.Net.Bluetooth.RadioMode.Connectable;
            InTheHand.Net.Sockets.BluetoothClient cli = new InTheHand.Net.Sockets.BluetoothClient();
            InTheHand.Net.Sockets.BluetoothDeviceInfo[] devices = cli.DiscoverDevices();
            foreach (InTheHand.Net.Sockets.BluetoothDeviceInfo device in devices)//设备搜寻
            {
                device.Update();
                device.Refresh();
                MessageBox.Show("设备已找到");
                break;
            }

 


            BluetoothDeviceInfo bd = new BluetoothDeviceInfo(devices[0].DeviceAddress);
            bluetoothClient = new BluetoothClient();


            Guid mGUID = Guid.Parse("fa87c0d0-afac-11de-8a39-0800200c9a66");
            bluetoothClient.Connect(devices[0].DeviceAddress, 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

            ReceiveThread = new Thread(ReceiveMethod);
            ReceiveThread.Start();

 

            return true;
        }

接下来用手机接受pc的链接请求：

 if (connected)
              {
                   return;
                }
              try
                 {
                     mBThServer = myBluetoothAdapter
                              .listenUsingRfcommWithServiceRecord(NAME_SECURE,
                                      MY_UUID_SECURE);
                 } catch (IOException e)
                 {
                     // TODO Auto-generated catch block
                     e.printStackTrace();
                 }
 
                 try
                {
                    mBTHSocket = mBThServer.accept();
                 } catch (IOException e)
                 {
                     // TODO Auto-generated catch block
                     e.printStackTrace();
                 }
                 try
                 {
                     mBufferedReader = new BufferedReader(new InputStreamReader(
                             mBTHSocket.getInputStream()));
                } catch (IOException e1)
                 {
                     // TODO Auto-generated catch block
                     e1.printStackTrace();
                 }// 取得输入、输出流
                 try
                {
                     mPrintStream = new PrintStream(
                            mBTHSocket.getOutputStream(), true);
                     connected = true;
                 } catch (IOException e)
                {
                     // TODO Auto-generated catch block
                     e.printStackTrace();
                 }

通过手机来发送数据：

接下来是pc端的接受代码：

到这里代码基本完成，但是我们需要注意的是：

我们一定要注意库函数的版本，版本不对是一件很麻烦的事情。

手机中的蓝牙设备也一定要打开。

好了 就到这里！！！
