I struggle using the companion app.

When I start it without tangara plugged in, I get a window that tells me to plug tangara in.
However, when I do, nothing changes.

When I start it with tangara plugged in, I get a completely empty window.
Not sure, what to do.



Any idea, what I'm doing wrong?


(Just installed the latest flatpak version on my debian system.)

Just learned how to open a flatpac from command line.

Ok, it seems to drop some errors:

Code:

flatpak run zone.cooltech.tangara.Companion

Seems to be some permissions missing.
Will try to run it with some sudo rights. Not sure if that one is a good idea...

edit: I seems that sudo doesn't work with flatpaks ...

Seems I have to add me to the group "dialout"

as:

Code:

sudo usermod -a -G dialout $USER

Took from here: https://github.com/haileys/tangara-compa...2620456509

Finally, seems that the group "dialout" was the key.

Now I could update the firmware.
