Unable to get OctoPrint connection to 3D printer working on /dev/ttyAMA0 after upgrading from Mate 20.04 to Mate 22.04. (Fresh install of everything done twice already) Hardware is a Creality CR6-SE with community firmware connected to Pi4 with 8GB in Argon case with 250GB SSD (Kernel Linux 5.15.0-1013-raspi aarch64)
Any help would be greatly appreciated. * * *
ERROR Log Info:
Connecting to port /dev/ttyAMA0, baudrate 115200
Serial detection: Handshake attempt #3 with timeout 2.0s
M110 detected, setting current line number to 0
Changing monitoring state from "Detecting serial connection" to "Error"
Changing monitoring state from "Error" to "Offline after error"
Same results running Octoprint in Safe Mode
User is a member of tty & dialout groups
Have also tried deleting tty & ttyAMA0 from the /dev directory
(Appears to have most the of same issues that accompanied having the brltty.service (Braille service) running in version 20.10, but 22.04 doesn't load the brltty.service.)
I am no expert at reading dmesg data, but nothing jumps out as a problem to me.

YOU ARE 100% CORRECT in your POST!!!
I finally got there myself before reading your answer by unplugging and plugging the printer and looking at sudo dmesg results.
Looks as if your solution WORKS as suggested. But, I had tried to do `sudo systemctl disable brltty.service' and with service at the end it failed to find the service and failed to correct my problem.
The FIX I used is found at: [usbfs: interface 0 claimed by ch34x while 'brltty' sets config #1 路 Issue #18 路
From the comments it appears several others have used it successfully also.
