qrtools don't decode a router wifi code

Hello!

Sorry for the long delay. Could you please attach the QR code if possible so I can debug better the problem?

Also, please try using the latest version from the Daily PPA and check if the problem persists.

Thanks!

[Expired for QR Tools because there has been no activity for 60 days.]

This bug keeps qtqr failing when scanning WIFI qr codes generated by FritzBox. Attached a PNG of the failing QR Code. Its content is:

"WIFI:S:WifiName;T:WPA;P:605234075537023465159873240561365314585632096534;;"

$ qtqr --version
QtQR version 2.0

$ zbarcam --version
0.23.1

Actually the current code differs from original post, so my stack trace looks different as well:

Traceback (most recent call last):
  File "/usr/bin/qtqr", line 837, in decodeWebcam
    if qr.data_decode[qr.data_type](qr.data) == 'NULL':
  File "/usr/lib/python3.9/site-packages/qrtools.py", line 110, in <lambda>
    'wifi' : lambda data: re.findall(u"WIFI:S:(.*);T:(.*);P:(.*);[H:]+(.*);", data, re.IGNORECASE)[0],
IndexError: list index out of range

Looks to, as if "[H:]+(.*)" may be empty (missing "H:"), but regEx does not match in that case.

Changing "[H:]+(.*)" to "[H:]*(.*)" helped in my case, Will create a pull request on GitHub :)

Hi!

Yes, the regex fix looks ok. The H (used for hidden networks) field is
optional.

Please be aware that the official repo is here on launchpad. If you found
something on GitHub is not official.

Thanks!

Indeed. I first found an old fork on github, which confused me. I am currently trying to crate an push a new branch with bazaar, but I am completely new to this. Its a one-character fix. Do you need a branch (not even shure if you have Pull requests in bazaar)?

finally pushed my branch to https://code.launchpad.net/~pokulo/qr-tools/bugfix_wifi_code_hidden_flag

Thank you Pokulo. I've merged your branch into trunk. The fix should be available in the Daily PPA soon.

Have a merry Christmas and a happy new year.

Thanks, same to you! Which Version will contain that bugfix? (I have arch linux actually, so I have to wait for our maintaner here https://archlinux.org/packages/community/any/qtqr/).

Sorry for the delayed answer. The version should be qtqr-2.1-0~rev43.

The deb packages are here if it helps somehow:
https://code.launchpad.net/~qr-tools-developers/+archive/ubuntu/daily/+packages

Sadly I don’t control the packages for different OS.

Best regards,

Ramiro

Thanks! I flagged the arch linux packages as out-of-date with reference to this bug-thread.

Thank you!
