So I tried again yesterday with the Freematics One latest code on github. Here's the status: Works: SD card logging (MEMS data only) MEMS accelerometer Doesn't work: OBDII functionality GPS (no communications) Not tested: SIM800L SMS/GPRS functionality I was suspicious about the GPS. I hooked it up ...

Yeah, I was trying my Freematics One out with the new libraries last Wednesday and couldn't get anything beyond the accelerometer working. No ODBII (tried on 2 cars with compatible protocols) due to timeouts, no communication with the GPS (NO DATA NO DATA etc.) and a blank log file on the SD card (0...

We'll mount an RFID reader in the car, connect it to the Freematics One and use it to unlock the doors when t...
