Hi,
I would like to ask you question about OBD II library and ELM327 Bluetooth. My idea was to connect Arduino Uno HC-05 with ELM327 by bluetooth connection using AT Commands. The question is if it is possible to use those libraries after that: GitHub - stanleyhuangyc/ArduinoOBD: OBD-II library and sketches for Arduino or if they are only for freematics devices? If i can not maybe you know another library that i could use?
