How to set up betaflight fc with Ubuntu

Betaflight for ubuntu

1. Create a rule for the DFU

$ (echo '# DFU (Internal bootloader for STM32 MCUs)' echo 'ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", MODE="0664", GROUP="plugdev"') | sudo tee /etc/udev/rules.d/45-stdfu-permissions.rules > /dev/null
 
 2. Monitor connection and find your model (unplug/plug the fc while this cmd is active)
 
$ udevadm monitor --environment --udev | grep ID_MODEL_ID
 
 3. Update the /etc/udev/rules.d/45-stdfu-permissions.rules file with your model. E.g, my MODEL_ID is 5740, and the .rules file
 ends up like this:
 
 # DFU (Internal bootloader for STM32 MCUs)
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", MODE="0664", GROUP="plugdev"

# ix5 
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="5740", MODE="0664", GROUP="plugdev"
 
4. Now reload rules

$ sudo udevadm control --reload-rules && udevadm trigger

5. You can then test the rule using when your FC is plugged in:

$ udevadm test $(udevadm info -q path -n /dev/ttyACM0)

Ensure line "MODE 0664 /etc/udev/rules.d/45-stdfu-permissions.rules" is present

6. Now check the group at which the device belongs to

You can then test the rule using when your FC is plugged in:

$ ls -lah /dev/ttyACM0 
crw-rw---- 1 root dialout 166, 0 mars  17 21:57 /dev/ttyACM0

Here it is in dialout, obviosuly thinking it is a modem. 

7. Stop the modem service

$ sudo systemctl stop ModemManager.service

8. Add yourself to the group plugdev and dialout (don't know which one is the "correct one")

$ sudo usermod -G plugdev -a <username>
$ sudo usermod -G dialout -a <username>

9. I had to reboot for this to work. 

Ubuntu 22.04.2 LTS

Firstly, for Betaflight Configurator to actually work with flight controllers, current user was added to "dialout" group:

sudo usermod -aG dialout $USER ($USER - system variable that contains the current user login);

Then, created low-priority rule for STM32 devices:

(echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ACTION=="add", MODE="0664", GROUP="dialout"') | sudo tee /etc/udev/rules.d/80-local.rules

Then - reloaded udev rules:

sudo udevadm control --reload

That solved the problem for me.
Much appreciated the authors effort; used

Dear NightCrack thank you very much!
