解析從藍牙HDP設備接收的原始數據
[英]Parsing raw data received from bluetooth HDP device
問題描述
我正在嘗試從連續健康聯盟認證的歐姆龍708-BT血壓監測儀中讀取數據。 我正在關注這個藍牙HDP應用程序的例子。 我正在設法連接到設備並以字節格式檢索數據，但無法解析數據以獲取所需的值。 我正在嘗試遵循本PDF第19頁中指定的IEEE血壓規范。
以下是已添加到上面鏈接的示例代碼中的代碼。

數據的十六進制表示如下。 我相信這些數據可以保持血壓值的值，但可能是錯誤的。 我認為這是唯一的原因是因為在上面鏈接的PDF中，數據將以十六進制值e7開始。

我設法解決了這個問題。 我遇到的主要問題是我只接受了一次血壓讀數，然后繼續按下上傳。 這會上傳一些有關顯示器的信息，但不包括血壓讀數。 一旦我知道了這一點，我就有其他一些較小的錯誤要解決，但沒有太復雜。 最終工作服務的代碼如下。

afaik你必須在自動或推送上傳之間進行選擇。
如果自動工作並且您可以讀取數據，則只需禁用自動上傳並在測量后直接通過上傳按鈕將數據推送到您的設備...
問候

您可能應該將data_AR中正確的設備地址發送回設備 - 在您的情況下：002209225835c328
因此你應該交換：
(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,
有：
(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,
並且還使用0x00 0x03 result = accepted-unknown-config類的
final byte data_AR[] = new byte[] {
(byte) 0xE3, (byte) 0x00,
(byte) 0x00, (byte) 0x2C,
(byte) 0x00, (byte) 0x03,
編輯：
我犯了一個錯誤 - 地址不是您的BPM-DEvice而是您的電話...要從48位MAC地址中獲取EUI 64位地址，只需在中間拆分並添加0xFF 0xFE，如： BT 48bit MAC [00:11:22:33:44:55]變成了
EUI 64 Bit [00:11:22:FF:FE:33:44:55]
我很抱歉

我從這里讀IEEE： IEEE 11073-20601-2008
請查看CLause 7.4.4的第57頁：
代理發起的測量數據傳輸由代理發送，例如，作為采取的新測量的結果。 管理者通過發出命令（即，MDS-數據請求）來指示代理開始或停止發送測量數據來明確地請求管理者發起的測量數據傳輸。 取決於代理的能力，該報告模式活動時的時間段是可配置的（例如，固定時段或始終在關聯時）。 經理應支持從代理收到代理和經理發起的測量數據傳輸。 代理可以支持代理和管理器發起的測量數據傳輸中的一個或兩個的生成。 在代理和管理器發起的測量數據傳輸中，事件報告用於攜帶測量數據。
