whatever I install needs to be compatible with MicroPython if websocket doesn't work, I have no idea why it's throwing an error
also i just doxxed myself rofl woopsies
IP:port is a working ip and port with a websocket server listening for connections

So TLDR the docs are fubar and the internet is unhelpful, contradictory, and flat wrong
The flattening of the error message appears to be due to stack traces being off for memory and performance reasons
If you're upset with thonny pycharm has a plugin for this
The internet suggests MicroDot for a library to use for this
It appears microdot is the more modern alternative to what used to be done more manually with uasyncio. Microdot uses the functioning asyncio library so it should be less janky.
I see you're using urequests
the relevant websockets library that comes itwh that is uasyncio.websocket.server
Hopefully that's all helpful

also I'm using Thonny if you couldn't tell
using MicroPython (RP2040) for the Raspberry Pi Pico W

anyway tldr websockets doesnt micropython
rotund tulip
they have a built in library called websocket and there absolutely has to be a way to do this
the whole point of the pico W is wifi connectivity I dunno how you can really use that effectively without websockets
I'm not giving up on this if I find something I'll put it here but it's not looking promising
so I'm starting to think bluetooth might be the way to go
bleak umbra
the relevant websockets library that comes itwh that is uasyncio.websocket.serve...
see this
you have some options
rotund tulip
oh my messages were incredibly delayed and I didn't see any of that
does usyncio have a client? the pi is supposed to be the client
its seeming like the only way to do this is either use socket and manually set up the actual websocket stuff or use microdot and do essentially that minus a little bit of the work
I am so confused on why websocket exists if it doesn't work
bleak umbra
It works on other devices. It's unfortunately designed for systems that don't mind a bit of heavier weight for more convenient development.
