Apologies in advance for incorrect terminology, this is my first time using Modem Manager.
I have a Raspberry Pi Compute 3+ Module running Bookworm OS (64-bit) connected to a Quectel EC25-AF modem. I need to disable Modem Manager from accessing the TTY USB ports (0-3) because it interferes with other hardware connected to the Pi.
On Raspberry Pi Bullseye (which ran Modem Manager v1.14), the following udev rule would allow the modem to connect over QMI.
However, on Raspberry Pi Bookworm (which runs Modem Manager v1.20), the QMI protocol fails and it tries to connect using the AT port (which is disabled due to the above udev rule)
Has anyone had success connecting to a cell network through the QMI protocol on a Raspberry Pi running Bookworm?
