Freematics Forum

Also updated to the latest code as of today.

Even when it appears working, most ELM commands just return a question-mark, which is frustrating -- does this mean that the ELM327 emulation in the Freematics ONE is hobbled compared to the one's in the UART and I2C versions? Even the extended AT commands don't work (e.g., ATTEMP), although ATRZ co...

If it matters, it's the IDE on macOS. I don't think that should matter though.

I have a Smart ForTwo. If I run the EMU327 software, I can ATZ and ATDP shows "AUTO, ERROR" even though I'm pretty sure the car uses 11/500 CANBUS. So I can ATSP6 (Ok) and ATDP shows, "AUTO, ISO 15765-4 (CAN 11/500)", but any commands respond with CAN ERROR or "SEARCHING...U...
