Hi - sorry, but we don't support CAN on ESP32 via Espruino at the moment. If you wanted to use it with Espruino you'd have to build your own firmware with some C code in, as shown in https://www.espruino.com/Extending+Espruino+1.
I'm afraid it's not something that is very high up our priority list for ESP32 at the moment so it's likely not something I would work on - but if someone added it and sent a PR I'm happy to merge it!
