連接/配對藍牙耳機和Android

我想創建一個簡單的程序，掃描藍牙耳機（我正在測試一個PS3耳機），然後連接到它。我正在使用bluetooth chat program example中的代碼。但是我無法將它連接到任何東西。當它到達connect（）時它給我一個I/O異常。連接/配對藍牙耳機和Android

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

此線程在嘗試與設備建立傳出連接時運行。它貫穿始終;連接成功或失敗。

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); 
     } 
    } 
}

這裏是logcat的：

任何幫助深表感謝。

謝謝克里斯

我正在使用2.2更新版和PS3藍牙耳機在Droid X上進行測試。它正在配對，但不會連接。當我進入藍牙設置時，我可以手動連接耳機。 – 2010-10-14 17:02:27

我想你不應該指定一個特定的UUID作爲連接PARAM除非你知道這是你的耳機提供確切的GUID。我不確定。但我希望它能幫助你。

祝你好運！

@CHRIS嘿，我其實只是想通了這個問題。您用connectThread敲打頭部，但是您需要使用UUID（「00001108-0000-1000-8000-00805F9B34FB」）作爲耳機配置文件。我使用的是Jabra耳機，適用於我。讓我知道你是否有疑問！謝謝！

某些藍牙耳機可能不提供此配置文件UUID，儘管它是用於此目的的基本配置文件。但是，隨着車載套件使用的「更高」級別配置文件增加了一些有趣的功能（重撥最後的號碼等），您應該首先嚐試使用UUID爲「0000111E-0000-1000-8000-00805F9B34FB」的HandsFreeProfile（HFP）。 – Schlangi 2013-07-17 11:56:12

我正在研究類似的問題以及... - 如何連接耳機配置文件的APP。然後，我在這裏看到了這樣的回答： https://stackoverflow.com/a/5711736/769556

基本上這個耳機的水平輪廓連接是通過的Android內部完成（有沒有應用級訪問建立連接）

左右。 .. @ Chris Mattmiller你有沒有找到不同的答案？
