android - Android 用の hdp デバイスからのデータの解析 (API 15)

Question

私は HDP サンプルを使用しており、血圧センサー (http://www.andonline.com/medical/products/details.php?catname=&product_num=UA-767PBT-C) を持っています。私はそれからデータを取得しますが、それを人間が読める形式に解析する方法がわかりません。

これは私が今まで次のようなもので試したことです:

while(fis.read(data) > -1) {
    String value = null;
    BigInteger bi = new BigInteger(data);
//  for(byte b:data){
//  value+=b;
//  }

Log.d("read data binary", "the data "+bi.toString(2));

Log.d("read data decimal", "the data "+bi.toString());

Log.d("read data hexa", "the data "+bi.toString(16));

Log.d("read data pure", "the data "+data);

//  Log.d("read data in for", "the data "+value);

そして、私は次のようなものを取得します:

誰でもそれを解析する方法を知っていますか?

PS: logcat からすべてを入れて申し訳ありませんが、誰かが何らかの接続を見つけるかもしれません

Answer 1

解決策を見つけました。センサーが送信した正確なバイト数 + センサーが情報を送信する方法が必要でした。

血圧モニターのデータを解析するクラスの一部を配置します。

 public String byte2hex(byte[] b)
    {
     // String Buffer can be used instead
       String hs = "";
       String stmp = "";

       for (int n = 0; n < b.length; n++)
       {
          stmp = (java.lang.Integer.toHexString(b[n] & 0XFF));

          if (stmp.length() == 1)
          {
             hs = hs + "0" + stmp;
          }
          else
          {
             hs = hs + stmp;
          }

          if (n < b.length - 1)
          {
             hs = hs + "";
          }
       }

       return hs;
    }

    public static int byteToUnsignedInt(byte b) {
        return 0x00 << 24 | b & 0xff;
      }

    // Thread to read incoming data received from the HDP device.  This sample application merely
