Freematics Forum

I have received Freematics One + a month ago as a replacement for Freematics One that has never worked properly in my car.
My car is Seat Altea and uses the KWP2000 5Kbps protocol.
For example, I have not been able to read the entire VIN from the car. Neither from Freematics One nor FreematicsOne ...

I have exactly the same problem. But when I switch speed to 57000Baud, it works 3 out of 5 times to connect and upload firmware.

Hi Stanley

The latest updates to Freematics One 4 can not compile. Errror shows mssing datalogger.h.

Cann´t upload the zip.

Hi Stanley

Just so you know.
The last 6-8 updates of the library have meant that the KWP ISO 14230-4 KWP 5 baud has not worked with Freematics One

Hi,

I'm having trouble to get GPS to work. Data logging to SD works fine and stable without GPS but when I try with GPS, logging stops after <1 min. and the LED stops flashing and lights instead constantly.
The GPS is a M8030 and is set to 11500 and 10Hz
Connection is K-line slow.

Any suggestions?

I have the same problem. The UBX-M8030 only works with 38400 baud, but the data logger only works for approx. 2 min and go to sleep. The UBX-M8030 can be programmed to another baud rate - 115200, but are there some who can help with a sketch?
