Is this with the "latest" version esp32 software? I remember improving the update a while ago and it is reliable here.

I don't know which version I have, but my last update attempt ended in disaster and I bought a new one.

Oh I remember now. That was in April in the last software change was in March. So you have the latest one.
Can you CAN(log)?

Hi,
I have a situation with a foccci / custom BMS, I've had the exact same setup in the past and it's working flawlessly. But the new one keep giving me can timeout error when charging CCS2 on a EcoFactor station.
I was able to do a screen grab just after the charging station stopped.

I should be sending the can messages at 250ms interval, what is the Timeout set at in Foccci ?
Does someone had a similar issue before ?

The wiki is talking about 2s or 3s timeout https://openinverter.org/wiki/Foccci
Any chance to log the CAN traffic, to understand whether there are such long gaps in the communication?

Both the params "ChargeCurrent" and "enable" needs to be received over CAN to reset the timeout, the time out is spotvalue "CanWatchdog"

I would like to install Foccci on our race car. Is there a DBC file coming with the board ?

Not how OI works, all spot values can be sent or recieved over CAN so its upto you to configure.
