A few questions all related: I fly FPV drones which require to use betaflight to configure them over the serial port. This has been working ok in the past and is getting more and more confusing. The timeline is far from accurate but in short:
Everything used to work fine a few Fedora releases ago (not so many)
dmesg now requires sudo
Yes, that change happened recently. Do something like https://unix.stackexchange.com/a/401626.
Thank you all for clarifying. I guess I'll keep sudo for dmesg for security reasons.
- Serial port also requires sudo ( /dev/ttyACM0 ) for betaflight to be
able to access it
Add your user to dialout group. Something like:
sudo usermod -a -G dialout fmuller
Likewise thank you for that one too!
- dmesg doesn't show the serial port connection happening anymore since
about after Monday 12th and therefore I can't do anything anymore.
Sounds unusual.
Yeah.. I figure it out, put on my "close-view" glasses, realized it was not a USB C cable connecting, tried another one and... it worked! Obviously I was using one of those non-data capable cable and no data was going through that port. My bad.
At least I've fixed the com port access and understood why dmesg requires sudo now.
Thank you everybody.
