I'm sure it's not the message itself that is interrupting your download. The message indicates that the wifi reconnects during your download and therefore the download fails. I don't know the reason for this. But you could try disabling wifi sleep according to https://docs.micropython.org/en/latest/...

Yes, that is the workround. You can't install V3 by copying Python files because it relies on C modules. You have to have a firmware build which supports it. The c file is optional last time I checked and it works in Unix by copying the files. Of course it would impact performance and ram usage if ...

For retrieve uasyncio v3.0 lib version, i can download it at https://github.com/micropython/micropyt ... d/uasyncio) and put inside "/lib/" directory as module on ESP8266.. Or frozen it before compile new custom firmware, right? This might be one way but the better way would be to enable uasyncio b...

@kevinkk525 I have but I don't know what these sizes tell you about fitting on small boards as I have no experience of them: Not completely sure but I always assumed that the size of firmware-combined.bin is the actual firmware size. The difference between the module size and the firmware would be ...

You can try to build the firmware yourself with uasyncio included.
My firmware builds were always a lot smaller than 1M so I'm not sure why uasyncio would be dropped for the 1M firmware but I haven't yet built a firmware for the esp8266 with the new uasyncio.

The Unix port of micropython does not have that because it has no hardware pins.
If you want to use the Unix build for debugging, you will have to provide a "fake" machine module implementation.

Easy example: mqtt uses sockets but multiple asyncio tasks can send messages. Each send operation might need multiple steps with "await" in between but the currently sending task has to prevent other asyncio tasks from using the socket until the transmission is finished. Therefore a lock is used.

However, once number of devices increased to 11 I started to get no readings from several sensors.
