I'm currently trying to build a device that can read Car's VIN number and send it over Bluetooth connection to an Android phone..

Yes, I'm aware that not all car support this. So far what I'm aware of is by the ELM327 (to communicate data from car to bluetooth module) and the HC-05 (to communicate data from ELM327 to Android).

But, I'm quite unsure on how to make this works, since I have 0 (zero) experience with the OBD-II. I'd appreciate if anyone could help me with reference and stuff.
