GC closes unexpectedly after connecting to arduino in Win8 64 bit

[raynerzed]

GC 1.19 closes immediately upon connection to the arduino. Everything was setup correctly. Doesn't happen when changed version to GC 1.18

Thanks for opening an issue on this. In the GroundControl folder within the GroundControl-Windows.Portable.v.1.19 folder you'll find a file log.txt. It would greatly aid troubleshooting if you could zip that and attach it to a post here. It should contain information about the cause of the crash.

log.txt
Here you go :)

Well_that's_ disappointing 🙁, no smoking guns... Here's something to try - disconnect the Arduino and start GC1.19 - does it stay running until the Arduino is connected, or crash before then?

Good news, kind of - 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 #749 . When the new groundcontrol.ini file is created, the section for propweightz in [Computed Settings] is not created.

The quick-and-dirty workaround is to add this line to groundcontrol.ini at the end of the [Computed Settings] section.
'''
propweightz = 1

'''

Darn, sorry for really causing a mess here! I'll start looking into why this is happening right now. Any thoughts on what I did differently with this setting than the others?

Edit: I can reproduce the issue with traceback:

That PR looks like it is 'reversed' - the variable should not be deleted?

[BarbourSmith]

I'm not sure I understand, which variable is it that is deleted?

[blurfl]

Sory, shouldn't be responding from up onm a ladder 😁
PR#747 changed main.py:199 to remove the propWeightZ. Could this be the cause of this issue?

[BarbourSmith]

Directing software development from up on a ladder 😁

I think you are 100% correct. I've opened #753 to put the missing variable back in
