汽車OBD II 接口硬體+軟體與hack筆記
通用硬體為Elm327,現在普遍用電腦或手機走藍芽uart.
AT command指令集.插入車上OBD II接口.

CAN 2.0B規範包含Phy實體層跟資料連結層(Data Link Layer)，看狀況還需要高層協定(Higher
Layer Protocols, HLPs)。

有些儀器會"參考"(Sniffer)別人的診斷儀，甚至是原廠的
中國某汽車診斷設備廠商被趕出北美，就是因為Sniffer福特的原廠診斷儀，又被福特抓包了。不過即便如此，XX診斷儀在美國黑市上依然非常受歡迎。
而福特原廠抓包道通的方式，也是sniffer 道通的設備，發現了自己埋進去的無效指令竟然被照抄了...
資料救援設備大廠ACE Lab 也有做車用檢測儀.
現在資料救援設備都會加入無效指令集
來防範被同行抄襲

現在調表跟clone keyless都需要100%掌握行車電腦...

【空氣品質的監測與淨化，可以更細膩！】

上週我們探討過關於環境氣體的「質化」分析(https://www.facebook.com/lookcompotech/posts/1533589426740342)，若想進一步開拓相關應用，還須輔以「量化」分析。關注空氣清靜機的朋友，應該對 Honeywell 不陌生吧！但大家可知道它是如何智慧偵測 PM 2.5 濃度？又怎麼與物聯網 (IoT) 結合？

Honeywell PM 2.5 採用「光散射法」的雷射感測器，可對已知環境中、每立方公尺之 0～1000 μg 範圍內的微粒進行檢測，並即時計算出微粒濃度值，再將數據傳送給 IoT 模組並回傳至後台閘道器 (Gateway)——支援 USB、Wi-Fi 及乙太網傳輸介面，最後將感測器資訊上傳到雲端平台。

系統支援 AT Command 指令集，可以短字串指示撥號、斷線及改變通訊參數的動作，對感測裝置進行資料採集。當濃度值偏高時，清淨機的風扇轉速會拉高；反之，數值減低時會降速，動態維持良好空氣品質。除了居家環境，還能用於檢測大賣場等工商場域的二氧化碳 (CO2) 濃度，或部署於智慧路燈偵測戶外環境空氣品質；一旦有害氣體濃度過高，可示警以提早因應。

IoT 模組與 Gateway 使用 RISC 精簡指令集架構的 32 位元微處理器 (MCU)，RF 收發器有 FSK、GFSK、OOK 等調變方式，支援 2.4GHz / 868 MHz / 915 MHz / 433 MHz 頻段以及 6 LoWPAN、ZigBee、WirelessHART 等多種基於 IEEE 802.15.4無線通訊協議，最大連線節點數達上百個。它採用 Contiki 即時作業系統，尤其適合小型嵌入式聯網裝置；內建數據加密演算法，可阻絕惡意竊取感測數據。

特別一提的是，使用者可藉 Windows、Linux 作業系統的 Cross Complier Toolchain 與 SDK 開發套件進行二次開發。
