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.
- 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
- 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.
I´ve read that the serial port access problem could be due to group permissions so some guidance would help but in general I'd be happy to run both dmesg and the serial port from my user, and eventually understand why suddenly connecting the flight controller to the serial port (USB that is) doesn't seem to work anymore.
