Hi,
Please forgive me if this list is not an appropriate venue for my question. I'm trying to get an integrated
Sierra Wireless MC7750 Modem (Verizon 4G LTE) up and running using the latest ModemManager (0.7/0.8), libqmi,
and NetworkManager 0.9.8.
The modem works reliably on Windows. I have also successfully gotten it to work (once!) on Linux, but the
configuration failed to survive a reboot. It currently gives the following error when I try to connect using
NetworkManager:
kma bree ~ $ !nmcli
nmcli con up uuid 7a80b6d4-a52d-40c7-b279-7533422ff01e
Error: Connection activation failed: The connection was not a 3GPP2 connection.
This occurs very quickly, *as if* somehow Network Manager isn't even attempting to ask ModemManager to make
the connection (but I don't actually know this). It certainly doesn't cause ModemManager to spit out its own
errors simultaneously. (Both are logging debug level info). I would expect to see complaints from
ModemManager as well, but all I get is the NetworkManager error.
Any ideas how I managed to actually get a completely working configuration after installing updated package
builds --- but before rebooting --- and nothing but this 3GPP2 connection activation error since?
Unfortunately, one of the many things I tried doing after the reboot was deleting and re-creating the 4G LTE
connection in nm-connection-editor.
As an aside, how can I tell if we're trying to go through QMI or AT commands? Is there a way to force either
one? Is there a way to force a connection to a particular device in the system-connections directory? Is it
possible some USB devices got shuffled around after rebooting?
I have also managed to get the the WWAN network up once or twice without Network Manager as follows:
bree kma # more wwan_up.sh
#!/bin/sh
mmcli -m /org/freedesktop/ModemManager1/Modem/0 --set-allowed-modes=ANY --set-preferred-mode=3G
mmcli -m /org/freedesktop/ModemManager1/Modem/0 -e
qmi-network /dev/cdc-wdm0 start
dhclient -d -4 wwan0
bree kma # ./wwan_up.sh
successfully set allowed modes in the modem
successfully enabled the modem

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd reload
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the reload(8) utility, e.g. reload smbd
bound to 10.171.246.73 -- renewal in 3169 seconds.

However, this method is not reliable.
Modem Manager is clearly talking to the modem, as a sample of the following debug output indicates:
