Freematics Forum

Email stanley directly. I think he only uses github as a repository.

Won't the freematics unit have to be powered all the time in order for this to work? I've killed cars leaving OBD2 stuff plugged in that were low power consumption. Dunno about the freematics unit.

Google ELM327. You'll find the AT commands there. That is the chip the freematics unit uses to read OBD2 data. for GSM/GPS, it's in the code. You'll have to figure that out.

The sketch is already on it (I guarantee that much). But the repository to get the latest code is here: m somewhere in there anyway. The rest is arduino stuff you'll have to figure out and learn. You really need to hook up the serial connection and debug to see what's going on. I don't know much abo...

Your original post said you got the SD card with it. That's odd, usually stanley preloads the SD card with at least a sample log.

There should be something on it. Or did you not buy the SD card with the arduino? If not, it only supports up to a certain size SD card.

The power is likely always on in your car. So unless you wire it to a switch, I wouldn't advise leaving the unit plugged in.

The SD card shouldnt be empty. Stanley always puts at least a folder into it. What year/model is your car?

Some cars leave the OBD2 port hot all the time so if its on when the car is off, its most definitely draining about batter.

Is that a motorcycle specific think? I've had a few kwp issues in the past with cars. Maybe this would help fix them.

I would unplug the freematics unit and THEN turn off the car. Otherwise, the values being read are junk.

On the product page, you can pick your GPS unit. The code is already made to detect and log if it's there.
