I wouldn't worry about flash cycles on an esp8266 (and not just because they are dirt cheap). During my development I often end up uploading the whole firmware 20 times a day. For every change I make, I compile and flash a new firmware (which is ~700kB). And none of my devices have had any problems ...

The only thing one has to be careful about is to use bytes and not strings. If the topics/messages are short, it will work either way. But if they are longer then the topics/messages will break the communication because they might get sent in multiple operations and therefore split into multiple par...

It's possible that the 1M still doesn't include the module uasyncio? It was not included earlier but I remember having had a discussion about it.

I have topics like home/binary_sensor/77c0b900/status/config and everything works just fine.

esp-idf has nothing to do with the repl, it's just the startup garbage and wifi debug messages and the likes. the repl comes from micropython and you can use the webrepl to control and program your device.

This should work for the esp8266 in the same way: https://forum.micropython.org/viewtopic.php?f=2&t=7844&p=44765&hilit=os.dupterm#p44765 (I'm sure I read posts about the esp8266 and esp32 too but can't find it at the moment) If you compile the firmware with no esp-idf output, the uart should be comp...

Alright, thanks for the info. (Just in case you or anyone reading this thread doesn't know this: The repl uart can be removed from the repl and used independently. For this alone, no micropython fork would be required)

I was using https://github.com/dmascord/micropython since I need a UART. I tried again, but failed. Damien (dmascord) is going to help me with the UART, so I have to get that running again. Can you explain the differences between this fork and the main micropython? The uart on the esp8266 is availa...

One question ... line 22 <make axtls> is just to confirm everything is OK or is this step absolutely required?

Unless the dependencies changed, this line is required. It might be possible to not need it if all tls/ssl modules are disabled but I'm not sure about that.

I have the esp8266 micropython build with the pfalcon esp-open-sdk working in this script: https://github.com/kevinkk525/pysmartnode/blob/dev/tools/esp8266/esp8266_get_repository.sh I should point out that this thread is only about the esp-open-sdk and has nothing to do with the pfalcon micropython ...
