Setting up EM7430 internet connection on Linux


I’m trying to enable internet connectivity using an EM7430 connected to an LTE eNodeB. Testing on a Raspberry Pi, the EM7430 gives an eth1 and eth2 interface as well as /dev/qcqmi0 and /dev/qcqmi1. Which combination of these should be used to set up an active internet connection? Neither of the eth1 or eth2 interfaces have an IP address.

I’m a little confused on all the drivers and interfaces (GobiNet, GobiSerial, ppp, cdc_ether, option, usb_wwan, qmi_wwan, etc).

What is the process for connecting to the internet given a Linux installation and EM7430? If possible, I would like this to be scripted instead of using Modem Manager.



Check the attached out, it was written for the MC73 but the principles and commands remain the same.
