I want to try this module for my Sierra Wireless 7455 LTE modem so I read this tutorial. Installed all modules and this is the network config:
config interface 'broadband' option device '/sys/devices/platform/101c0000.ehci/usb1/1-1/1-1.3' option proto 'modemmanager' option apn 'internet.it'
All seems ok but this what the new interface sais:
Anybody use ModemManager and know if my config is right?
