Very nice :)
One more thing, we forgot to add some examples (and then also to CI). These 2 should be working?

Here, in both of these, WiFi.firmwareVersion(); is used, which is not available for our port. I can comment out those lines and add those.

Yes, if you see the other examples, I have removed those as well, and adapt a bit to the returns we have in our WiFi class.
Anything that is not necessary we can remove. But all this can be also taken in a new ticket.
