Android到个人电脑RFCOMM频道

Question

所以即时通讯工作的应用程序，直接连接通过蓝牙接受来自RFCOMM通道的字符串命令并发送响应。

所以这些都是2类我目前正在与

Bluetooth_Manager

import android.bluetooth.*; 
import android.content.Intent; 

public class Reader_BluetoothManager { 

    protected Reader_MainScreen main; 
    protected BluetoothAdapter bAdapter; 
    private Reader_AcceptThread bAccept; 

    public Reader_BluetoothManager(Reader_MainScreen main) { 
     this.main = main; 
     initiate(); 
    } 

    public void initiate(){ 
     checkForBluetooth(); 
     enableBluetooth(); 
    } 

    public void log(String l){ 
     main.log(l); 
    } 

    public void checkForBluetooth(){ 
     bAdapter = BluetoothAdapter.getDefaultAdapter(); 
     if (bAdapter == null) { 
      main.log("No Bluetooth supported!"); 
      return; 
     } 
     main.log("Bluetooth supported..."); 
    } 

    public void enableBluetooth(){ 
     if (!bAdapter.isEnabled()) { 
      main.log("Bluetooth not enabled... requesting activation"); 
      Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE); 
      main.startActivityForResult(enableBtIntent, main.BLUETOOTH_ENABLE_CODE); 
     } 
    } 

    public void enableConnection(){ 
     main.log("Connecting..."); 
     if (bAccept != null) 
      bAccept.interrupt(); 
     bAccept = new Reader_AcceptThread(this); 
     bAccept.start(); 
    } 

    public void stopConnection(){ 
     if (bAccept != null) 
      bAccept.interrupt(); 
    } 
} 

而且AcceptThread

import java.io.IOException; 
import java.util.UUID; 

import android.bluetooth.BluetoothDevice; 
import android.bluetooth.BluetoothServerSocket; 
import android.bluetooth.BluetoothSocket; 

public class Reader_AcceptThread extends Thread{ 

    private BluetoothServerSocket serverSocket; 
    private BluetoothSocket socket; 
    private BluetoothDevice device; 
    private Reader_BluetoothManager main; 


    public Reader_AcceptThread(Reader_BluetoothManager main) { 
     this.main = main; 
    } 

    public void run(){ 
     try { 
      serverSocket = main.bAdapter.listenUsingRfcommWithServiceRecord("XXXXXX", UUID.fromString("00001101-0000-1000-8000-00805F9B34FB")); 
      main.log("checkPoint 1"); 
      socket = serverSocket.accept(); 
      main.log("checkPoint 2"); 
      device = socket.getRemoteDevice(); 
      main.log("checkPoint 3"); 
      main.log("connection established..."); 
      main.log(socket.toString()); 
     } catch (IOException e) { 
      main.log("error..."); 
      main.log(e.toString()); 
      main.main.stopConnection(); 
      interrupt(); 
     } 
     while (!isInterrupted()){ 
      try { 
       sleep(2000); 
      } catch (InterruptedException e) { 
       interrupt(); 
       break; 
      } 
      main.log("ping"); 
     } 
    } 
} 

工作，我这些根据谷歌文档指南构成。 同样在我的笔记本电脑，我正在做以下几点：

，这是，什么是发生在我的电话：

这里，发生了什么，当我尝试从连接我的Windows PC：

正如你可以看到在手机屏幕截图我卡在socket = serverSocket.accept()。

您所使用的UUID是该服务的UUID - 如果你想使用默认的RFCOMM通道，你应该使用SPP UUID "00001101-0000-1000-8000-00805F9B34FB"代替UUID.randomUUID();

serverSocket = main.bAdapter.listenUsingRfcommWithServiceRecord("Connection Test", UUID.fromString("00001101-0000-1000-8000-00805F9B34FB"));
