Question

你好

我有一个疯狂的想法，试图以编程方式从我的Android设备连接到我的Apple AirPods，并尝试“记录”传入的信号（例如，当AirPod连按两次，从耳朵拿出，电池报告等时）。）由于我之前从未尝试过任何Android蓝牙产品，因此我研究了一些文档，观看了一些教程并编写了以下代码：

//In my main activity, this gets called when my AirPods have been successfully connected to my Android device
private void connectedToDevice(BluetoothDevice device)
{
    mLog("Attempting to read data...");
    BTConnectionService mConnection = new BTConnectionService();
}

这是BTConnectionService类：

private static final UUID MY_UUID = UUID.fromString("0000110E-0000-1000-8000-00805F9B34FB");

private final BluetoothAdapter mBluetoothAdapter;

private AcceptThread mAcceptThread;
private ConnectedThread mConnectedThread;

public BTConnectionService(Context context)
{
    mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
    start();
}

private class AcceptThread extends Thread {

    private final BluetoothServerSocket mServerSocket;

    public AcceptThread()
    {
        BluetoothServerSocket tmp = null;

        try
        {
            tmp = mBluetoothAdapter.listenUsingInsecureRfcommWithServiceRecord(APP_NAME, MY_UUID);
            Log.d(TAG, "AcceptThread: BluetoothServerSocket established."); 
        }
        catch (IOException e) { e.printStackTrace(); }

        mServerSocket = tmp;
    }

    public void run()
    {
        BluetoothSocket socket = null;

        try { socket = mServerSocket.accept();
            Log.d(TAG, "run: mServerSocket.accept()"); }
        catch (IOException e) { e.printStackTrace(); cancel(); }

        if(socket != null)
        {
            mConnectedThread = new ConnectedThread(socket);
            mConnectedThread.start();
        }
    }

    public void cancel()
    {
        try { mServerSocket.close(); } catch (IOException e) { e.printStackTrace(); }
    }
}

private class ConnectedThread extends Thread {

    private final BluetoothSocket mSocket;
    private final InputStream mInStream;

    public ConnectedThread(BluetoothSocket socket)
    {
        mSocket = socket;
        InputStream tmpIn = null;

        try { tmpIn = mSocket.getInputStream(); }
        catch (IOException e) {e.printStackTrace();}

        mInStream = tmpIn;

        Log.d(TAG, "ConnectedThread: set up");
    }

    public void run()
    {
        byte[] buffer = new byte[1024];
        int bytes; //bytes returned from read()

        while(true)
        {
            try
            {
                bytes = mInStream.read(buffer);
                Log.d(TAG, "READ: " + bytes);
            }
            catch (IOException e) { break; }
        }
    }
}

public synchronized void start()
{
    Log.d(TAG, "BTConnectionService started.");
    if(mAcceptThread == null)
    {
        mAcceptThread = new AcceptThread();
        mAcceptThread.start();
    }
}

我的问题是mServerSocket.accept()从不返回任何内容。我是否必须以某种方式将传递给listenUsingInsecureRfcommWithServiceRecord方法的“名称”和“ uuid”与目标设备进行匹配，否则我做错了什么？我对此很陌生。我的代码对我来说似乎太模糊了，根本没有考虑连接的设备，但这是我唯一可以在网上找到的东西。预先非常感谢。
