android (API 15)의 hdp 장치에서 데이터 구문 분석

Question

HDP 샘플을 사용하고 있으며 혈압 센서가 있습니다 (http://www.andonline.com/medical/products/details.php?catname= & product_num = UA-767PBT-C). 나는 그것으로부터 데이터를 얻었지만 그것을 사람이 읽을 수있는 것으로 파싱하는 방법을 모른다.

이 내가 좋아하는 뭔가 지금까지 뭘하려 :

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); 

과 나는 같은 것을 얻을 :

사람은, 제발 구문 분석하는 방법을 어떤 ideea의있다?

추신 : 로그 캣에서 최선을 다하는 죄송합니다,하지만 어쩌면 누군가가 나는 해결책을 발견 모든 연결

Answer 1

를 찾습니다. 내 센서가 보내고있는 정확한 바이트 수 + 센서가 정보를 보내는 방식이 필요했습니다.

나는 혈압계의 데이터를 분석하는 클래스의 부분을 넣을 것이다.

     { 
      stmp = (java.lang.Integer.toHexString(b[n] & 0XFF)); 

      if (stmp.length() == 1) 
      {
