it logs the same thing 2 more times (3 trys of connecting) and then gives:

i am using the newest flatpack version of the app on debian. any help would be appreciated! thanks.

Interesting, looks like your Q30 is running firmware version 03.50, but the newest available for mine is 02.30. I guess it's probably a newer model or something with slightly different behavior. Looking into it.

FWIW I just installed the latest Windows build to see what would happen, and it's working for me.

Mine came with 03.50 from factory.

@Mrnofish Thanks, that's useful to know and possibly leads me to the answers to all my questions.

The Q30 does not have a custom transparency mode (vocal mode/fully transparent) and custom noise canceling strength setting, so those values are usually valid but ignored. None of the valid values for those settings exceed 0x0A, but @matanton666's Q30 is reporting 0xFF for the noise canceling mode, custom transparency mode, and custom noise canceling settings.

I assumed 0xFF was supposed to be null essentially, and the device would override whatever its actual value is and report 0xFF when the setting is not applicable. However, it's possible that the device just accepts whatever value you throw at it, and 0xFF just happened to end up getting set for whatever reason and it's unrelated to the firmware version. I'll check if this is the case later.

Should be fixed in v1.10.5. https://github.com/flathub/com.oppzippy.OpenSCQ30/pull/13 is merged, so it shouldn't be too long until it's available on flathub. Please let me know if the issue still occurs.
