Hi there! This is a pretty horrendous, beta quality (should be alpha) parser. 😃

I added some code to allow it to grab more fields. It's not pretty and I'm not sure how much more time I'll spend on this parser since so many of the fields are unknown. I hope this helps!

This update will make it into the v1.25.4 release. You can test it in the meantime by copying the parser file to your plugin directory:

https://github.com/kellyjonbrazil/jc/blob/dev/jc/parsers/iw_scan.py

  • Linux/unix: $HOME/.local/share/jc/jcparsers
  • macOS: $HOME/Library/Application Support/jc/jcparsers
  • Windows: $LOCALAPPDATA\jc\jc\jcparsers

Let me know how it goes!
