When I will have usocket running with lwIP over USB, I will revisit the connected ESP01 and get hopefully "real" Wifi networking for the Pico.

Awesome, that was the long term goal I was hoping for!
Would be great if you get lwip over uart using an esp01/esp8266/Esp32 working.

This looks like a lot of development effort and it's great that it works, but I can't find a reason for this? Maybe you can explain it to me. What's the point of forwarding the network of a PC to the Pico? I could just do anything on the PC directly and any PC would be an expensive network adapter. ...

I'm still working on my implementation of a socket over uart with an Esp32 or esp8266 as the wifi module but it's going rather slow due to my personal situation. I have a small working code, it communicates fine with an echo server but it's far from good enough for mqtt because currently there is no...

If you use rshell to connect to the esp8266 then rshell sets the rtc to the PC time.

Maybe I'm missing something but my understanding is, that if anything should be missing, it's the end of the message, not the start? Wh, would "heart" disappear? Apart from that I never used readline() but would expect it to only return something when it had a full line (otherwise returning none?). ...

In V3 you can always clear down an event immediately after setting it: I think this is normally the best way to use the class as it keeps the set/clear logic in one place. This avoids risks of an event being set and not cleared. I would highly recommend not to do that. It's not a matter of how V3 w...

Don't clear the event in the reading method, let the main loop do that. As for the 2 seconds delay, you can change that by turning your main loop around a bit: async def update_display(display): # if needed wait a few ms on startup while True: print('Update display') display.fill(0) display.text('Te...

You can poll all events like: a=[event1,event2,event3] for event in a: if event.is_set(): # process LCD event.clear() await asyncio.sleep_ms(20) The downside is obviously that it checks all the events every 20ms and is therefore less efficient than awaiting a single event directly. Also it might tak...

ds.scan() is unlikely to throw an exception. In my application I catch oneWire errors on conversion and any type of error on reading: https://github.com/kevinkk525/pysmartnode/blob/0cd27d9aecdac334abbd70d939d03d68832e164b/pysmartnode/components/sensors/ds18.py#L148 https://github.com/kevinkk525/pysm...
