Hello,
I am using the modemmanager on openwrt (master).
While playing around, I noticed that it might be useful to trigger
an event after the modemmanager has detected a modem.
We already use '/usr/lib/ModemManager/connection.d' one a successful
connection.
There's already such interface, but it is not one provided by
ModemManager, but ModemManager re-uses one from Freedesktop. You can
watch for new modems by using the Freedesktop ObjectManager:
https://www.freedesktop.org/software/ModemManager/api/latest/ref-dbus-standard-interfaces-objectmanager.html
Background:
I use an APU3 with an EC25, which supports one SIM slot.
However, the APU3 has two sim slots that are switched via a GPIO pin.
After switching, I have to restart the modem so that it recognizes the
new SIM.
Now it would be good if I could change the SIM credentials after the
modemmanager
has been detected the rebooted modem and tell the netifd to reestablish
the connection with an 'ifup wwan'.
So far I only see the event in the syslog.
