Sounds like the problem may actually be that the kernel modules are missing, or the M.2/pcie interfaces are not set up yet.  Is this for a new board or a fully supported board?

Best,

Nicholas

After I created two interface, still same problem. I did notice some message in system log. Thank you for your help. This is my first time compile openwrt package with modemmanager.

You need one for the modem, which uses the modemmanager protocol, and one DHCP client interface which gets the IP from the modemmanager interface after it connects to the cellular network.  Check alexander0m’s bitbucket profile with the modemmanager-openwrt repository, there is an example config there.  After you get that all set up, assuming your wwan0 interface is in raw_ip mode, which I think is required for 7455’s in QMI mode, then you should simply be able to connect using ifup broadband && ifup wwan.
