java - 解析从蓝牙 HDP 设备接收到的原始数据

Question

我正在尝试从经 continua 健康联盟认证的 Omron 708-BT 血压计读取数据。我正在关注这个蓝牙 HDP 应用程序的示例。我正在设法连接到设备并以字节格式检索数据，但无法解析数据以获取所需的值。我正在尝试遵循本PDF第 19 页指定的 IEEE 血压规范。

这是已添加到上面链接的示例代码中的代码。

//Variables in the class

数据的十六进制表示如下。我相信这些数据包含血压值的值，但可能是错误的。我相信这是因为在上面链接的 PDF 中，数据将以十六进制值 e7 开头。

我设法解决了这个问题。我遇到的主要问题是我只读取了一次血压读数然后一直按上传。这确实上传了一些关于显示器的信息，但不包括血压读数。一旦我知道这一点，我就有许多其他较小的错误要解决，但没有什么太复杂的。最终工作服务的代码如下。

数据缓冲区包含 2 字节值和 4 字节值。正如您在 pdf 中看到的那样，可能是短裤和整数。你对此负责吗？

0xE7 0x00           APDU CHOICE Type (PrstApdu)  
0x00 0x84           CHOICE.length= 132  
0x00 0x82           OCTET STRING.length = 130  
0x00 0x01           invoke-id (differentiates this message from any other outstanding)  
0x01 0x01           CHOICE (Remote Operation Invoke | Confirmed Event Report)  
0x00 0x7C           CHOICE.length = 124  
0x00 0x00           obj-handle = 0 (MDS object)  
0x00 0x00 0x10 0x15 event-time (set to 0xFFFFFFFF if RelativeTime is not supported)  
0x0D 0x1C           event-type = MDC_NOTI_CONFIG

@Jieqin - 太好了，你也明白了 :)

将此粘贴到您的阅读线程中

//work for legacy device...
if (data[18] == (byte) 0x0d && data[19] == (byte) 0x1d)  //fixed report

afaik 您必须在自动或推送上传之间进行选择。

如果自动工作正常并且您可以读取数据，则只需禁用自动上传并在测量后通过上传按钮将数据直接推送到您的设备......

问候

Answer 5

您可能应该将 data_AR 中的正确设备地址发送回设备 - 在您的情况下：002209225835c328

因此你应该交换：

(byte) 0x00, (byte) 0x08,  //bt add for phone, can be automate in the future

(byte) 0x3C, (byte) 0x5A, (byte) 0x37, (byte) 0xFF, 

(byte) 0xFE, (byte) 0x95, (byte) 0xEE, (byte) 0xE3,

和：

(byte) 0x00, (byte) 0x08,  //bt add for phone, can be automate in the future

(byte) 0x00, (byte) 0x22, (byte) 0x09, (byte) 0x22, 

(byte) 0x58, (byte) 0x35, (byte) 0xc3, (byte) 0x28,

也可以使用 0x00 0x03 result = accepted-unknown-config类似的

final byte data_AR[] = new byte[] {         
             (byte) 0xE3, (byte) 0x00,
             (byte) 0x00, (byte) 0x2C, 
             (byte) 0x00, (byte) 0x03,

编辑：

我犯了一个错误-地址不是您的 BPM-DEvice 而是您的手机...要从您的 48 位 MAC 地址中获取 EUI 64 位地址，只需将其拆分在中间并添加 0xFF 0xFE 如下： BT 48bit MAC [00:11:22:33:44:55]变成

EUI 64 Bit [00:11:22:FF:FE:33:44:55] 

我很抱歉

我从这里阅读了 IEEE：IEEE 11073-20601-2008

请参阅第 7.4.4 条第 57 页：

代理发起的测量数据传输由代理发送，例如，作为进行新测量的结果。管理器发起的测量数据传输由管理器通过发出命令（即，MDS-Data-Request）明确请求，以指示代理开始或停止发送测量数据。根据代理的能力，此报告模式处于活动状态的时间段是可配置的（例如，固定时间段或始终关联时）。管理器应支持从代理接收代理和管理器发起的测量数据传输。代理可以支持生成代理和管理者发起的测量数据传输之一或两者。在代理和管理者发起的测量数据传输中，事件报告用于携带测量数据。
