如何从蓝牙条码扫描器读取数据符号CS3070到Android设备

在我的项目中,我必须使用条形码扫描器Symbol CS3070通过蓝牙阅读条形码.即;我必须通过蓝牙建立 Android设备和条码扫描器之间的连接.任何人都可以告诉我如何从条形码阅读器读取值,以及如何设置通信？我已经阅读了 Bluetooth Developer Guide,我不想在蓝牙键盘仿真(HID)模式下使用条码阅读器(我有一些可以使用软键盘和条形码读取器填充的文本视图,我无法控制焦点)

我会使用这样的线程与读者通信

private class BarcodeReaderThread extends Thread {
    private final BluetoothServerSocket mmServerSocket;

    public BarcodeReaderThread(UUID UUID_BLUETOOTH) {
        // Use a temporary object that is later assigned to mmServerSocket,// because mmServerSocket is final
        BluetoothServerSocket tmp = null;
        try {
            // MY_UUID is the app's UUID string,also used by the client code
            tmp = mBluetoothAdapter.listenUsingRfcommWithServiceRecord("BarcodeScannerForSGST",UUID_BLUETOOTH);
            /*
             * The UUID is also included in the SDP entry and will be the basis for the connection
             * agreement with the client device. That is,when the client attempts to connect with this device,* it will carry a UUID that uniquely identifies the service with which it wants to connect.
             * These UUIDs must match in order for the connection to be accepted (in the next step)
             */
        } catch (IOException e) { }
        mmServerSocket = tmp;
    }

    public void run() {
        BluetoothSocket socket = null;
        // Keep listening until exception occurs or a socket is returned
        while (true) {
            try {
                socket = mmServerSocket.accept();
                try {
                    // If a connection was accepted
                    if (socket != null) {
                        // Do work to manage the connection (in a separate thread)
                        InputStream mmInStream = null;

                        // Get the input and output streams,using temp objects because
                        // member streams are final
                        mmInStream = socket.getInputStream();

                        byte[] buffer = new byte[1024];  // buffer store for the stream
                        int bytes; // bytes returned from read()

                        // Keep listening to the InputStream until an exception occurs
                        // Read from the InputStream
                        bytes = mmInStream.read(buffer);
                        if (bytes > 0) {
                            // Send the obtained bytes to the UI activity
                            String readMessage = new String(buffer,bytes);
                            //doMainUIOp(BARCODE_READ,readMessage);
                            if (readMessage.length() > 0 && !etMlfb.isEnabled()) //Se sono nella parte di picking
                                new ServerWorker().execute(new Object[] {LEGGI_SPED,readMessage});
                        }
                        socket.close();
                    }
                }
                catch (Exception ex) { } 
            } catch (IOException e) {
                break;
            }
        }
    }

    /** 
     * Will cancel the listening socket,and cause the thread to finish
     */
    public void cancel() {
        try {
            mmServerSocket.close();
        } catch (IOException e) { }
    }
}

谢谢

解决方法

我刚刚收到我的设备,当我配对并连接设备时,会自动将数据发送到当前关注的EditText.您使用的是什么版本的Android,因为我在ICS和JB上尝试使用它,并且这样做.
我没有在任何早期的版本中测试它.

编辑：

我把手机降级到了姜饼,发现它不行,但是我有一个解决方案：

这个很重要！ >>首先,您必须扫描手册中的“串行端口配置文件(SPP)”中的条形码.

btAdapter = BluetoothAdapter.getDefaultAdapter();
if (btAdapter.isEnabled())
{
    new BluetoothConnect().execute("");
}

public class BluetoothConnect extends AsyncTask<String,String,Void>
{
    public static String MY_UUID = "00001101-0000-1000-8000-00805F9B34FB";

    @Override
    protected Void doInBackground(String... params)
    {
        String address = DB.GetOption("bluetoothAddress");
        BluetoothDevice device = btAdapter.getRemoteDevice(address);
        try
        {
            socket = device.createRfcommSocketToServiceRecord(UUID.fromString(MY_UUID));
            btAdapter.cancelDiscovery();
            socket.connect();
            InputStream stream = socket.getInputStream();
            int read = 0;
            byte[] buffer = new byte[128];
            do
            {
                try
                {
                    read = stream.read(buffer);
                    String data = new String(buffer,read);
                    publishProgress(data);
                }
                catch(Exception ex)
                {
                    read = -1;
                }
            }
            while (read > 0);
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onProgressUpdate(String... values)
    {
        if (values[0].equals("\r"))
        {
            addToList(input.getText().toString());
            pickupInput.setText("");
        }
        else input.setText(values[0]);
        super.onProgressUpdate(values);
    }
}

这是我工作代码的不完整版本,但你应该得到要点.我希望这个解决方案也适合你！
