Hi Aleksander,
Thanks for your reply. I will check your advice. In addition, I find
that MM only show the primary AT port of the LTE module.
Is that related to the *without-udev or without-libqmi*? I have tried to
add the other ports to MM, but MM still only show the *ttyUSB2(at)*.
mmcli --report-kernel-event="action=add,subsystem=tty,name=ttyUSB2"
mmcli --report-kernel-event="action=add,subsystem=tty,name=ttyUSB0"
mmcli --report-kernel-event="action=add,subsystem=tty,name=ttyUSB1"
mmcli --report-kernel-event="action=add,subsystem=tty,name=ttyUSB3"
mmcli --report-kernel-event="action=add,subsystem=tty,name=ttyUSB4"
mmcli --report-kernel-event="action=add,subsystem=usbmisc,name=cdc-wdm0"
Best Regards,
Brian
