Freematics Forum

Hi,

I'm using my freematics and almost finished my project for remote EV monitoring when, during a long term test something strange happens.

Normally I receive a timeout or response data to my PIDs, but this time I always instantly receive $OBDNO Data (enabled headers)

the normal AT commands respond OK, like expected.

Do you still have this issue?
I have noticed that datalogger will happily record OBD data during the first run after booting.
When I park the car and later restart the engine, only the GPS data is recorded, not my selected PIDs.
