============
|
|
|
|
|
|
Important notice
|
|
----------------
|
|
|
|
If you are using a mobile device with integrated WWAN module, a manual
|
|
configuration step is needed after installing or upgrading modemmanager,
|
|
otherwise the module might NOT be useable anymore.
|
|
|
|
Unfortunately, the logged error message will be slightly misleading.
|
|
So, if you see a message like
|
|
|
|
<warn> [modem0] couldn't enable interface: 'Invalid transition'
|
|
|
|
in your system logs or ModemManager keeps enabling and disabling the
|
|
module every second, you are probably affected by this change:
|
|
|
|
Starting with release 1.18.4, ModemManager does no longer enable the
|
|
automatic FCC unlock for certain types of modems by default.
|
|
|
|
THIS MAY BREAK EXISTING SETUPS
|
|
|
|
You can restore the old behaviour AT YOUR OWN RISK by creating symlinks
|
|
in /etc/ModemManager/fcc-unlock.d:
|
|
|
|
sudo ln -sft /etc/ModemManager/fcc-unlock.d /usr/share/ModemManager/fcc-unlock.available.d/*
|
|
|
|
See https://modemmanager.org/docs/modemmanager/fcc-unlock/ for details.
