Question

我一直在尝试使用蓝牙RFCOMM连接Google Glass和Nexus设备，其中在Nexus设备上运行的应用程序充当服务器，并且The Glass尝试将客户端连接到同一个UUID。

答案：https://stackoverflow.com/posts/20414642/非常有用，虽然我无法获得所需的功能。连接部分没有问题，但基本上我想a）将一些数据传输到Android设备b）获取对Glass的响应。所以这是我想要的双向沟通。

我遵循了Android开发者网站上的蓝牙指南，我认为处理程序用于管理现有连接的方式需要进行修改。

Glass App上的处理程序

public Handler mHandler = new Handler(){
    @Override
    public void handleMessage(Message msg) {
        // TODO Auto-generated method stub
        Log.i(TAG, "in handler");
        super.handleMessage(msg);
        switch(msg.what){
            case SUCCESS_CONNECT:
                //read and write data from remote device
                unregisterReceiver(mReceiver);
                ConnectedThread connectedThread = new ConnectedThread((BluetoothSocket)msg.obj);
                connectedThread.start();
                Toast.makeText(getApplicationContext(), "CONNECTED", 2).show();
                //setContentView(R.layout.activity_main);
                break;
            case MESSAGE_READ:
                byte[] readBuf = (byte[]) msg.obj;
                int bufferContent = ByteBuffer.wrap(readBuf).getInt();
                String string = new String(readBuf);
                break;
        }
    }
};

在Glass App上运行的ConnectThread的run（）函数

public void run() {
            // Cancel discovery because it will slow down the connection
            mBluetoothAdapter.cancelDiscovery();
            Log.i(TAG, "connect - run");
            try {
                // Connect the device through the socket. This will block
                // until it succeeds or throws an exception
                mmSocket.connect();
                Log.i(TAG, "connect - succeeded");
            } catch (IOException connectException) {
                Log.i(TAG, "connect failed");
                // Unable to connect; close the socket and get out
                try {
                    mmSocket.close();
                } catch (IOException closeException) { }
                return;
            }
            // Do work to manage the connection, the handler will send the connecting successful message with the socket back to the pool
            mHandler.obtainMessage(SUCCESS_CONNECT, mmSocket).sendToTarget();
            // manage connected socket
            // manageConnectedSocket(mmSocket);
        }

套接字管理在Android设备上运行的连接

private void manageConnectedSocket(BluetoothSocket socket) {
        // start our connection thread
        mConnectedThread = new ConnectedThread(socket);
        mConnectedThread.start();
        // Send the name of the connected device back to the UI Activity
        // so the HH can show you it's working and stuff...
        String devs = "";

        for (BluetoothSocket sock : mSockets) {
            devs += sock.getRemoteDevice().getName() + "\n";
        }
        // pass it to the pool....
        Message msg = handle.obtainMessage(STATE_CONNECTION_STARTED);
        Bundle bundle = new Bundle();
        bundle.putString("NAMES", devs);
        msg.setData(bundle);
        handle.sendMessage(msg);
    }

方法的命名方案遵循官方文档中提到的方案 - http://developer.android.com/guide/topics/connectivity/bluetooth.html

我的问题是，这些方法/或任何其他允许将TextView的文本从Glass传输到Nexus设备的textView并返回的任何其他方法需要进行哪些更改。
