Thanks. Looks like there's some work done although it is not as easy as the OTA solution provided in loboris port for esp32.

Well you definitely need a way of uploading/downloading the new firmware (WLAN, I2C, some bus, GSM, ...) and an OTA module. ESP32 (at least loboris port) has an OTA module that can be used with WLAN and ethernet. I don't know about the pyboard and esp8266 does not seem to have support for that yet.

For remotely updating firmware your device has to be networked in some kind (WLAN, i2c, ...).
I don't know if anything is done in that direction. Apparently not even OTA works for esp8266 yet.

If your device is not networked, how is this going to work and how is this different than connecting a pc to it and flashing a new firmware?

That's not possible in python, only in lua.
If you want to have accessible globals you have to declare those in a module e.g. "config.py" and then import that module in every other file/module that wants to access these.

If you don't need updating configuration during runtime after the initial configuration has been received (as this would be very difficult as you have to unload the initial configuration first), you can have a look at my smarthome framework: https://github.com/kevinkk525/pysmartnode Changing configu...

Yes the header part will get allocated as it will be saved as a variable but as the header is very small, it can be ignored. I was a lot more concerned about the data part of the message which could get quite big but this does not allocate additional memory. At least not as far as I can tell. Ujson ...

Thanks for the clarification and the example! More interesting than the sending direction the other way, receiving the string 'myheader{"a": 1, "b": 2}' and converting it into header and dict: >>> c='header{"hi": "ho", "hoho": "hi"}' >>> s=uio.StringIO(c) >>> s.read(6) 'header' >>> json.load(s) {'hi...

please give us more details: content of set.txt, content of v1 (printed in the program), v2 and what is tmp??
My guess is, v1 still contains a newline character.

Edit: simultaneous post.. sorry

what would be a stringstream-like object? ujson could probably be used with a normal stream but not with uasyncio StreamReader as far as I know. But as this network layer receives a string object, it's not an option anyway. I guess that could be done but I lack the knowledge and implementing things ...
