java，BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();，BluetoothDevice device = bluetoothAdapter.getRemoteDevice(address);，BluetoothSocket socket = device.createRfcommSocketToServiceRecord(MY_UUID);，socket.connect();，OutputStream outStream = socket.getOutputStream();，File file = new File("path/to/file");，FileInputStream fis = new FileInputStream(file);，byte[] buffer = new byte[1024];，int bytes;，while ((bytes = fis.read(buffer)) != -1) {， outStream.write(buffer, 0, bytes);，}，outStream.close();，fis.close();，socket.close();，``java，new Thread(() -> {， while (true) {， try {， // 创建 socket 连接， Socket socket = new Socket("服务器地址", 端口号);， BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));， String line;， while ((line = reader.readLine()) != null) {， // 处理从服务器接收到的数据， System.out.println(line);， }， reader.close();， socket.close();， } catch (IOException e) {， e.printStackTrace();， }， // 间隔一段时间后再次尝试连接， try {， Thread.sleep(轮询间隔时间);， } catch (InterruptedException e) {， e.printStackTrace();， }， }，}).start();，``，，这段代码会不断尝试连接到服务器并读取数据，每次读取完成后等待一段时间再进行下一次连接。请根据实际情况调整服务器地址、端口号、轮询间隔等参数。Powered By Z-BlogPHP 1.7.3
