Android的BluetoothServerSocket和BluetoothSocket无法连接

发布于 2025-01-11 06:51:46 字数 12713 浏览 0 评论 0原文

我尝试开发一个蓝牙服务器客户端应用程序。但我在作为客户端连接时遇到问题。客户端不连接到服务器，它只是等待或尝试连接。设备未配对，我知道我们可以使用BluetoothServerSocket 来通信两个未配对的设备。

这里我的服务器端代码

    BluetoothServerSocket bluetoothServer;
    BluetoothAdapter mBluetoothAdapter;

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //displayText = (TextView) findViewById(R.id.display_text);
        //bluetoothServer = new BluetoothServer(handler, updateUI);
        //bluetoothServer.start();
        mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
        mBluetoothAdapter.enable();
        Log.i("bluetooth", "connecting<--------------");
        try {
            bluetoothServer = mBluetoothAdapter.listenUsingInsecureRfcommWithServiceRecord("helloService",
                    UUID.fromString("00001101-0000-1000-8000-008099999999"));
            bluetoothServer.accept();
            Log.i("bluetooth", "connected<--------------");
        }catch (Exception e){
            Log.e("error", String.valueOf(e));
        }

    }

服务器端代码的控制台输出：

如您所见，连接已写入，但未连接。

这是我的客户端代码：

        super.onCreate(savedInstanceState);

        bAdapter = BluetoothAdapter.getDefaultAdapter();
        bAdapter.enable();
        IntentFilter filter = new IntentFilter();

        filter.addAction(BluetoothDevice.ACTION_FOUND);
        filter.addAction(BluetoothAdapter.ACTION_DISCOVERY_STARTED);
        filter.addAction(BluetoothAdapter.ACTION_DISCOVERY_FINISHED);
        registerReceiver(mReceiver, filter);
        bAdapter.startDiscovery();
        Log.d("tag","######connecting########");
        try {
            BluetoothSocket socket = device.createInsecureRfcommSocketToServiceRecord(UUID.fromString("00001101-0000-1000-8000-008099999999"));
            socket.connect();
            Log.d("tag","######connected########");

        }catch (Exception e){
            Log.e("tag", String.valueOf(e));
        }


    }

这是我的客户端输出：

正如您再次看到的，连接文本已写入，但未连接。

虽然服务器端是 anroid 7，客户端是 android 11，

但应用程序的权限相同，如下所示：


    <uses-permission android:name="android.permission.BLUETOOTH_ADVERTISE" />
    <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
    <uses-permission android:name="android.permission.BLUETOOTH"/>
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
    <uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.LOCAL_MAC_ADDRESS"
        tools:ignore="ProtectedPermissions" />
    <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION"/>

I try to develop a bluetooth server-client application. But I have a problem about connecting as client. The client does not connect to server it just waits or trying to connect. The devices are not paired, I know we can use BluetoothServerSocket to communicate two no-paired devices.

Here my server side codes

    BluetoothServerSocket bluetoothServer;
    BluetoothAdapter mBluetoothAdapter;

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //displayText = (TextView) findViewById(R.id.display_text);
        //bluetoothServer = new BluetoothServer(handler, updateUI);
        //bluetoothServer.start();
        mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
        mBluetoothAdapter.enable();
        Log.i("bluetooth", "connecting<--------------");
        try {
            bluetoothServer = mBluetoothAdapter.listenUsingInsecureRfcommWithServiceRecord("helloService",
                    UUID.fromString("00001101-0000-1000-8000-008099999999"));
            bluetoothServer.accept();
            Log.i("bluetooth", "connected<--------------");
        }catch (Exception e){
            Log.e("error", String.valueOf(e));
        }

    }

console output of the server side codes:

As you see connecting is wroten but connected not.

Here my client side codes:

    BluetoothAdapter bAdapter;
    BluetoothDevice device;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        bAdapter = BluetoothAdapter.getDefaultAdapter();
        bAdapter.enable();
        IntentFilter filter = new IntentFilter();

        filter.addAction(BluetoothDevice.ACTION_FOUND);
        filter.addAction(BluetoothAdapter.ACTION_DISCOVERY_STARTED);
        filter.addAction(BluetoothAdapter.ACTION_DISCOVERY_FINISHED);
        registerReceiver(mReceiver, filter);
        bAdapter.startDiscovery();
        Log.d("tag","######connecting########");
        try {
            BluetoothSocket socket = device.createInsecureRfcommSocketToServiceRecord(UUID.fromString("00001101-0000-1000-8000-008099999999"));
            socket.connect();
            Log.d("tag","######connected########");

        }catch (Exception e){
            Log.e("tag", String.valueOf(e));
        }


    }

Here my output of the client side:
