为 android (API 15) 从 hdp 设备解析数据答案

【问题标题】：Parsing data from hdp device for android (API 15)为 android (API 15) 从 hdp 设备解析数据
【发布时间】：2012-05-01 18:26:41
【问题描述】：

我正在使用 HDP 样本并且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。

这是我到目前为止尝试过的类似：

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);

我得到类似的东西：

请问有人知道如何解析它吗？

PS：很抱歉把所有东西都放在了 logcat 中，但也许有人发现了任何联系

【问题讨论】：

能否至少告诉我们血液传感器的品牌和型号？
我刚刚在问题中添加了它。很抱歉没有意识到这是必要的:)
看看这对你有没有好处：wiki.eclipse.org/OHF_SODA_Stepstone
你好 Diana C，我也在开发相同的模块来从血压和脉搏信息医疗保健设备中检索信息。我能够与设备连接，但无法从设备中检索数据。我也使用过 BLE 和 GATT，所以它只适用于 Android 4.4+。如何从设备中检索信息以及如何使其与所有 android 设备兼容？你能帮我么？你能发给我任何演示吗？我也发布了问题。 stackoverflow.com/questions/29531224/…

【解决方案1】：

我找到了解决方案。我需要传感器发送的确切字节数+传感器发送信息的方式。

我将把解析数据的部分用于我的血压计。

 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 + "";
          }

为了理解此代码，您还必须阅读 IEEE 11073 规范。每种传感器都有自己的字节数。

这段代码不是我做的，有人给我的。如果他要求我删除它，我会:)

【讨论】：

您能否详细解释您的答案，因为我一直在解析来自 hdp 设备的数据。请帮帮我，你是怎么解决的。
非常感谢......我会用我的设备检查......并让你知道。
@Diana C 我也需要实现这个。你能告诉我 IEEE 11073 规范仅在 IEEE 网站或任何其他来源上可用。我的意思是它们是否可以作为开源提供？
