Thanks for the reply. Yea, I guess I sort of expected that, and of course most of the time we want that! Is there a "factory reset" type of operation for esp8266? I will go look on google. Anyway, what I have here is working for me to reset. Thanks again! I can't say enough about how much I love uPy...

Ok, so I may have worked around it with this code snipped. Before I added the active false and active true calls right before the last while loop, it would sit in the while loop even though I had set the ssid/pass to blank strings. But seems maybe after you do that take it down and back up and it wi...

Hi, I have a sort of weird question. So I am using a file "creds" on the nodemcu to store my wifi ssid and password. I have a case where I do os.remove() of that file on boot up if a button is pressed down, and I see that the file does get removed, but it also seems that then the wifi connection/cre...

So what is your version number of Python? You mentioned using python3, but oddly from this site it seems that JSONDecodeError should exist for python three: https://www.peterbe.com/plog/jsondecodeerror-in-requests.get.json-python-2-and-3 Let me raise the issue on github for uPyLoader and discuss the...

Well I'm remote on my phone so can't test but if you want try to do this:

sudo pip install simplejson

And then change that import to simplejson:

from simplejson import JSONDecodeError

I'm not sure why you can't import that module. You might want to just start up a python REPL prompt (just type "python3" or "python") and then when you get the >>> prompt try typing: from json import JSONDecodeError That's the line that's breaking for you. Maybe also try "import json" at the python ...

Ok, read up (https://bytes.com/topic/python/answers/ ... mory-usage and others) and I think it's better to just call the full import:

import machine

instead of:

from machine import UART

df() (disk-free) shows free file space, free() shows available ram. Thanks so much @devnull This seems to work great, I'll start keeping an eye on things and see how they change over development of my project. At one point I did crash just outright when I was importing modules, so I started cleanin...

Sure, thanks. I'm going to give it a go to use docker (https://github.com/dockcross/dockcross) to cross compile mpy-cross for windows and see if I can get an updated mpy-cross.exe that works for the latest firmware. I'm not familiar though with the "Pycom" version that roberthh has on his github htt...

Maybe I should also mention I am using the cross compiler for windows called mpy-cross_pycom.exe. I actually just tried using the latest firmware based on your question, and now I get "imcompatible .mpy file"? Hmmmm
