Hello everyone, I have tried to use a ELM327 OBD scan tool to talk to my Czero. During my tests, I have fixed the protocol of Czero to CAN 11 bits @500 K and my ELM327 tool responds correctely my AT commands, such as "AT CRA+ID" or "AT MA", but when I sent a simple OBD request like "01 00", "03"...
