Setting up a new Raspberry Pi Zero 2 W with a Prusa printer (fresh install)
Flash OctoPi on to SD card for a Raspberry Pi Zero 2 W (with wifi config)
Connect Raspbery Pi Zero 2 W via the GPIO serial connection to prusa MK3
What did you expect to happen?
On OctoPrint connecting via the auto settings didn't work
What happened instead?
Only AUTO was listed and connection kept failing.
Steps that solved the issue:
Under Settings > Serial Connection I had to add /dev/ttyAMA* to the additional ports (already present on the pi when connected via ssh)
added dtoverlay=disable-bt on new line at end of /boot/config.txt
removed console=serial0,115200 from /boot/cmdline.txt
run sudo systemctl disable hciuart.servic
run sudo systemctl disable bluetooth.service
run sudo reboot
Then I was able to connect without issues. For me the problem is solved, I'm reporting it as it could help other or either improve documentation or setup scripts. Feel free to close the issue if this isn't the correct place to report it :)
I was wondering however if it would be possible to include these settings while flashing the card or in the base image?
Some might be specific to the pi zero 2 so it might not be possible to have a generic solution so maybe documenting them helps, not sure if octopi or octoprint is the right place (I searched there first and then eventually found the correct page on prusa).
Did the same happen when running OctoPrint in safe mode?
