When running an example from the microdot_asyncio module I get the following error. Only change I made to the example code was to replace the example code from 'import asyncio' to 'import uasyncio as asyncio'. Traceback (most recent call last): File "/lib/microdot_asyncio.py", line 245, in dispatch_...

Thanks @bulletmark, I'll give your suggestions a try. I see you're from Brisbane. My most fond memory of Australia was getting to work briefly at the US Navy VLF (very low frequency) transmitter site in Exmouth, Australia. Exmouth is in the NW corner. Very cool setup, VLF is used to transmit to subm...

@jbar, what you have above seems fine so what you are actually running must be different. Copy the second example code here to main.py on your ESP32. Make sure you set up wifi (e.g in boot.py) and then reset. You should be able to connect to the IP address of the ESP32 on port 5000 and see Hello Wo...

Nico were you able to get your Microdot program to run? I'm trying to do something similar - turn relays on/off depending on temperature. I've got the relay control part programmed, but having issues using Microdot; as you said there are very few examples out there. If you could share your Microdot ...

@jbar, the microdot framework I referred to is first class quality. It is created by Michael Grinberg who is a renowned Python/Flask developer so we are very lucky he has contributed this package to the MicroPython community. You can use it in threaded or asyncio modes. I use it for my own asyncio ...

OP, the REPL is really for development use, not for your application. E.g. I use the Wifi REPL to copy my python and data files remotely to my devices (all around my house) and to watch diagnostic output as my program is running. For what you want to do, I would use an asyncio app which reads and w...

My answer to a recent similar post is appropriate to you also. Tried Asyncio, as you referred me to in other post. Actually for micropython it's uasyncio. Very neat module, and it works well on functions that complete themselves. ie no wait forever for acivity...like someone loading a webpage. As s...

Working to program an ESP32, to control a greenhouse fan by monitoring temperature and setting a relay to on/off as needed. Also want to be able to view webpage within my LAN showing temperature and fan (relay) status. For the webpage generation I'm using some code from a random nerd tutorial that p...

I don't have the answer but am interested in knowing the answer, hopefully someone answer your question..

You did not tell which board you use. Is it an ESP32? Or RPi Pico? And you could show the error message which you get.

The following message pops up in the shell:
Warning: I2C(-1, ...) is deprecated, use SoftI2C(...) instead

I'm using an ESP32.
