连接/配对蓝牙耳机和Android

问题描述：

我想创建一个简单的程序，扫描蓝牙耳机（我正在测试一个PS3耳机），然后连接到它。我正在使用bluetooth chat program example中的代码。但是我无法将它连接到任何东西。当它到达connect（）时它给我一个I/O异常。连接/配对蓝牙耳机和Android

private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");

此线程在尝试与设备建立传出连接时运行。它贯穿始终;连接成功或失败。

private class ConnectThread extends Thread { 
    private final BluetoothSocket mmSocket; 
    private final BluetoothDevice mmDevice; 

    public ConnectThread(BluetoothDevice device) { 
     mmDevice = device; 
     BluetoothSocket tmp = null; 

     // Get a BluetoothSocket for a connection with the given BluetoothDevice 
     try { 
      tmp = device.createRfcommSocketToServiceRecord(MY_UUID); 
     } catch (IOException e) { 
      Log.e(TAG, "create() failed", e); 
     } 
     if (tmp == null){ 
      Log.i(TAG, "tmp is NULL"); 
     } 
     mmSocket = tmp; 
    } 

    public void run() { 
     Log.i(TAG, "BEGIN mConnectThread"); 
     setName("ConnectThread"); 

     // Always cancel discovery because it will slow down a connection 
     mAdapter.cancelDiscovery(); 
     Log.i(TAG, "discovery is cancelled"); 

     // Make a connection to the BluetoothSocket 
     try { 
      // This is a blocking call and will only return on a successful connection or an exception 
      mmSocket.connect(); //Doesn't like something here??? 
     } catch (IOException e) { 
      Log.e(TAG, "IO error, ", e); 
      connectionFailed(); 
      // Close the socket 
      try { 
       mmSocket.close(); 
      } catch (IOException e2) { 
       Log.e(TAG, "unable to close() socket during connection failure", e2); 
      } 
      // Start the service over to restart listening mode 
      newTBluetoothService.this.start(); 
      return; 
     } 

     // Reset the ConnectThread because we're done 
     synchronized (newBluetoothService.this) { 
      mConnectThread = null; 
     } 

     // Start the connected thread 
     connected(mmSocket, mmDevice); 
    } 

    public void cancel() { 
     try { 
      mmSocket.close(); 
     } catch (IOException e) { 
      Log.e(TAG, "close() of connect socket failed", e); 
     } 
    } 
}

这里是logcat的：

任何帮助深表感谢。

谢谢克里斯

我正在使用2.2更新版和PS3蓝牙耳机在Droid X上进行测试。它正在配对，但不会连接。当我进入蓝牙设置时，我可以手动连接耳机。 – 2010-10-14 17:02:27

我想你不应该指定一个特定的UUID作为连接PARAM除非你知道这是你的耳机提供确切的GUID。我不确定。但我希望它能帮助你。

祝你好运！

@CHRIS嘿，我其实只是想通了这个问题。您用connectThread敲打头部，但是您需要使用UUID（“00001108-0000-1000-8000-00805F9B34FB”）作为耳机配置文件。我使用的是Jabra耳机，适用于我。让我知道你是否有疑问！谢谢！

某些蓝牙耳机可能不提供此配置文件UUID，尽管它是用于此目的的基本配置文件。但是，随着车载套件使用的“更高”级别配置文件增加了一些有趣的功能（重拨最后的号码等），您应该首先尝试使用UUID为“0000111E-0000-1000-8000-00805F9B34FB”的HandsFreeProfile（HFP）。 – Schlangi 2013-07-17 11:56:12

我正在研究类似的问题以及... - 如何连接耳机配置文件的APP。然后，我在这里看到了这样的回答： https://stackoverflow.com/a/5711736/769556

基本上这个耳机的水平轮廓连接是通过的Android内部完成（有没有应用级访问建立连接）

左右。 .. @ Chris Mattmiller你有没有找到不同的答案？
