I have two cars (both use CAN11B/500K, manufactured in 2009 and 2012) and two OBD dongles (clone ELM327 and Freematics ONE).
Car A
Both ELM327 and Freematics ONE are working fine.
Car B
ELM327 is working fine,
Freematics ONE is not working -> no response.
When I enable debug options, STM32 responde from ATZ, ATE0,. but not from 0100,...
I have specified OBD protocol to CAN11/500K instead of AUTO but nothing changed.
It looks similar to https://github.com/stanleyhuangyc/Freematics/issues/7 .
Since ELM327 is working, I suspect there's a compatibility issue. I read several posts in forum discussing the same issue.
I have logic analyzer, oscilloscope and National Instrument CAN device. Do you have any recommendation to solve the problem, or do you want more information?
