There are a couple other issues in the forum that are basically tied to the issue you described here. Glad to know I’m not the only one going crazy. I made a post showing my issue as well (Wio RP2040 Module wifi issues). I’m with you on the socket library issue. From what I saw, I would guess it’s a class syntax issue. I’ve done it a thousand times where I don’t include the reference back to the class object (self). Otherwise I can’t imagine why the function call to “bind” for my socket object would error out saying it doesn’t exist.
