2022, WIZwiki-W7500P, VSCode, PlatformIO, Getting Started???

Is there any good guide, blogpost, wiki, or article in getting started with the Internet features of the WIZwiki-W7500P? I have been able to get a blinking LED and also some text on a 16x2 character LCD, but moving to actually using the ioLibrary and getting a simple MQTT demo up and running is mystifying so far.

PlatformIO has several libraries, as does the wiznet github page, but they seem to overlap or be partial. PlatformIO does not seem to have the ioLibrary at all.

I should mention that I’m trying to use the mbed framework, and I understand that this dev board is not Mbed 6 compatible, which is fine, I guess.

Can someone help me understand how to get going on a MQTT demo (or similar)?

Thanks!
