The multi-core aspect can cause interesting challenges, especially if you’re using Arduino libraries that assume single core usage. Fortunately there’s really great synchronization primitives that you can use but if you come from an Arduino world it can be a shock. You have to be a lot more careful with interrupts and such to avoid causing crashes.

I’ve also found Espressif’s documentation to be exceptionally good which has been a big help.

If you’re doing any ESP32 dev work I strongly recommend getting a FT232H which can be used as a JTAG debugger if you don’t have a board with native capabilities otherwise debugging is really, really painful.
