Mini Mainboard and ESP32 CAN Web Interface

Post by ChristerE »

I just bought a Mini Mainboard and ESP32 CAN Web Interface & datalogger - community edition. I thought I could communicate with the Mini Mainboard via ESP32 CAN, that's possible, right?
Does the Mini Mainboard need to be updated or does it come with software out of the box?
Because I'm only getting 'Communication problem between ESP and STM'

Is there anyone who can guide me? That makes me happy!

Also if you only have the two on the bus close the solder jumper on the ESP32 to enable the 120 Ohm termination
