Hi, I am looking for Arduino OBD2 adapter. Something like "Freematics OBD-II Adapter" but this adapter must support ISO9141-2 protocol. Exist something adapter with this ISO? Thanks.
As far as I know the ELM327 supports ISO9141, so the Freematics adapter should work. Or you could try low level hardware and do the software yourself as this guy did: rvmiller.com/tag/iso9141/
Thank you for your response. Yes Freematics adapter should work but I read on the forums that does not work with ISO9141 :-/ I need an adapter to support at least ISO and KWP2000
I found this project Hack an ELM327 Cable.Do you think it would work?
I would think so. Give it a try.
