 ConfigParser.NoOptionError: No option 'propweightz' in section: 'Computed Settings'

Any idea's as to what's breaking it? Is there a way to remove the calibration cache and have it start with no previous calibration data?

Hardware is a raspberrypi 3B + touchscreen

ConfigParser.NoOptionError: No option 'propweightz' in section: 'Computed Settings'

That line sounds like the structure of the groundcontrol.ini file doesn't match what this version of GC expects; is this an old ini file with a much newer version of GC?
Here's something to try - rename your groundcontrol.ini file (save it for some of the numbers it contains). Then run GC. That will cause GC to create a new one with default values. If that works, you can transfer the values from the old file into the new one, either in a text editor of in GC's Settings and Advanced panels.

Good suggestions @blurfl . I tried to replicate this issue by deleting my .ini file and the issue didn't show up that way so I think @blurfl is right and renaming the .ini file should fix the issue

[sullit]

oh hi Bar, neat project :)

So that kind of worked, the python interpreter was still faulting with the same option error though so I appended an arbitrary 'propweightz = 20' into [Computed Settings] and it's at least now not breakpointing the python interpreter in the console output 🤷‍♂️

Thanks for the suggestions, is there any reference on the groundcontrol.ini file individual settings as they seem to be only generated by the calibrate function in the kivy app?

[BarbourSmith]

Thanks!

There isn't a documentation page for it but the code is fairly self documenting.

@BarbourSmith , PR #747 addresses this issue, right?

[BarbourSmith]

I think #747 caused the issue when upgrading, but I couldn't replicate it

[blurfl]

I'm able to reproduce this problem by flashing 'Blink.ino' and then the current firmware and removing groundcontrol.ini before starting GC.
This looks like the same issue as Issue #750 . When the new groundcontrol.ini file is created, the section for propweightz in [Computed Settings] is not created.

[BarbourSmith]

Thank you for the directions on how to reproduce this issue @blurfl, I was able to reproduce it in the same way. I have opened #753 to fix this issue

[sullit]

Cool i see you've traced it back to a missing function variable in main.py.

What's the git syntax to sync this PR or do you have to merge it with -master so we can update?

edit: oh nope, don't have to wait (how good is git?) so for the impatient it's git pull origin look-into-issue-750 from your local git controlled working directory

note: doing this will probably cause a version mismatch notification in the app, as both of Bar's working copies seem to be at v1.20

Warning, your firmware is out of date and may not work correctly with this version of Ground Control
Ground Control Version 1.20
Firmware Version 1.19

which should be ok to dismiss until 1.20 firmware has a release tag.

afaik there are no Python or Kivy specific flags to quieten this output with. so to diy you can quick-and-dirty your existing 1.19 to 1.20 in Maslow.h and reflash, or just wait for any significant upstream changes and a v1.20 tag in the firmware repo.
