分析来自android hdp设备的数据（API 15）

我使用的是HDP样本，我有一个血压传感器(http://www.andonline.com/medical/products/details.php?catname=&product_num=UA-767PBT-C）。我从中获取数据，但我不知道如何将其解析为人类可读的内容

这就是我迄今为止一直尝试的方法，比如：

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);

我得到的结果是：

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);
