WizFi360-EVB-Pico

9 Aug 2022

When the RPi Pico W was announced in June I was very happy as I've wanted to get an inexpensive WiFi version of the RP2040. Unfortunately, to date, I haven't been able to get one.

fmilburn mentioned in a Comment on New Pico W that "Wiznet has RP2040 boards for both ethernet and WiFi."

I noticed that the WizFi360 EVB Pico is available in distribution (Digikey less than $7).

And more recently I noticed on Hackster that Wiznet was having a design contest and giving away free samples for projects (3 different modules including the one with the Pico).

I applied and received a free sample. It arrived this weekend, slightly worse for shipping - the exterior box was crushed (I plumped it up a bit), but luckily the board was not (love those padded envelopes).

The WizFi board has a couple of shortcomings relative to the Pico W. It retains the Pico footprint/pinout, but is longer because the WiFi module is just tacked on the end. And it only does WiFi, while the Pico W uses an Infineon CYW43439 chipset capable of WiFi/BLE (although to be fair - BLE has not been implemented in the firmware yet).

I have a number of sensors that I use WiFi only, so I'll probably make good use of the WiZFi board and best of all it's available...

Hi Nico , The person that created the WizFi360_arduino_library had posted a project on Hackster using the wizfi360-evb-pico-in-arduino . I noticed that they had used version 2.2.2 of the RP2040 board…

Good grief! Good luck. Hope you get everything working before I get started .

So many hurdles, LOL...

In case you run into this - the next problem was that it doesn't interpret .local names, so I had to use the IP address. That got me connected, and it's sending data that's being received by NodeRed, finally!!

But then it runs out of sockets

This all works 100% on the ESP-based boards, btw. I'm finding the WizFi library has a lot of other little quirks too, like the way the SSID and password are defined are not the same as the standard WiFi libraries (the proper libraries just use string constants).
So I stand by my earlier outburst of this board not being polished enough for general use!

ah ok. so you might need to remove that line from the samples too... in case it comes up.
This is the line that caused the problems for me, in the samples:
> IPAddress ip = WiFi.localIP();

And... where is that "facepalm" icon... I was connecting the WizFi board to my GUEST network, which is purposely isolated from seeing the rest of my network. sigh. So hopefully that will solve the last hurdles!

Sorry, mislead you a bit. I was able to connect and observe (on the router) that I had obtained an IP address. I was not able to use the WiFi.localIP function - that hung as you experienced. That is one of the things I wanted to look at.

ps, good that you were able to connect and print out your IP address and have things working... I don't know why that doesn't work for me

It's possible they've broken that in the last week or so... I updated everything yesterday.
