Freematics Mega Kit - OBD-II UART Ver. 1.0 update?

[bino29]

Hi there,

I bought a Mega Kit and can't get any connection via OBD to my car. I saw the Firmware should be 2.1 for my OBD-II UART Adapter, but on the Arduino Display it shows Ver. 1.0.

Could this be my problem? How can I make a Firmware-Update?

Thanks

1.0 is the firmware version and 2.1 is the hardware version. That is fine. What car do you have?
