Your code doesn't even connect to wlan?

I've just build and flash the latest uPython firmware on my ESP32 board but I still can not see uasyncio.py to import . Could you explain more on how can I get asyncio.py modules from ?
appreciate in advance,

1. I don't know any mqtt server for micropython. Best to use a Pi Zero
2. The official uasyncio should be in your firmware already.
3. You can put any module into that directory to save RAM.

The log messages come from the ESP32 IDF. I think some of these messages can't be turned off due to bugs with the way the IDF log level checking works, but there is some control of this using esp.osdebug e.g. import esp esp.osdebug(esp.LOG_NONE) I don't normally use esp32 other than when I was work...

No, time.sleep() doesn't change the behaviour. It is just the recommended way. The messages in the repl are just debug messages, you can ignore them in your program. if you are writing to the repl, use wifi.active(False) to disable your wifi and they will go away. There should be a command for disab...

Apparently it doesn't find your AP so it never connects?
Therefore it doesn't stop printing those messages, unless you issue wlan.active(False)

A small note, use this instead of a busy loop:

If someone has access to #2 then it won't really matter if the key is stored on the device or retrieved and stored in RAM. He could still get it, the effort just gets bigger.

Because the leds on those boards might be low active, therefore active when the pin is pulled to ground.

well if that's not helpful to you then maybe try to ask your question again with correct spelling because I don't understand 80% of it.

Might want to try that to be sure the AWS IOT works as expected and doesn't need weird workarounds
