读取蓝牙设备数据并打印

Question

任何人都可以告诉我如何在 LogCat 中显示蓝牙设备（MyGlucoHealth 仪表）数据。以下代码：

InputStream is = btSocket.getInputStream();

如何从“is”中读取数据并打印出来。 ?

谢谢， 陈娜

查看BluetoothChat 示例。 ConnectedThread.run() 从 InputStream 读取数据。

    public void run() {
        Log.i(TAG, "BEGIN mConnectedThread");
        byte[] buffer = new byte[1024];
        int bytes;

        // Keep listening to the InputStream while connected
        while (true) {
            try {
                // Read from the InputStream
                bytes = mmInStream.read(buffer);

                // Send the obtained bytes to the UI Activity
                mHandler.obtainMessage(BluetoothChat.MESSAGE_READ, bytes, -1, buffer)
                        .sendToTarget();
            } catch (IOException e) {
                Log.e(TAG, "disconnected", e);
                connectionLost();
                break;
            }
        }
    }
