android 串口通信 ，系統(tǒng)休眠后，有概率出現(xiàn)數(shù)據(jù)丟包，在網(wǎng)上找到一篇文章，將串口讀數(shù)據(jù)部分代碼采取下面的方式，解決了該問題。

    /**
      * 串口讀數(shù)據(jù)線程

    public void run() {
        byte[] buf = new byte[6];
        while (!isInterrupted()) {
            try {
                if (null == mInputStream) {
                    return;
                }

                if (mInputStream.available() <= 0) {
                    continue;
                }else {
                    try {
                        Thread.sleep(50L);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }

                int read = mInputStream.read(buf);
                if (read > 0) {
                    byte[] readBytes = new byte[read];
                    System.arraycopy(buf, 0, readBytes, 0, read);
                    onDataReceived(readBytes);
                    Log.i(TAG, "run: readBytes = " + byte2hex(readBytes));
                }

                try {
                    Thread.sleep(10L);
                } catch (Exception e) {

            }
        }
        Log.e(TAG, "read thread over");
