[OpenWrt-Devel] Advice needed - Proper approach to port 5G/LTE modem into OpenWRT

[Jeonghum Joh]

Hello Bjørn,

What an honor to talk to you!
You are the author of the usbnet adapter kernel module!
Thank you for replying to me.

With your suggestions, I tried to search documents from openwrt documents
and found several:
https://openwrt.org/docs/guide-user/network/wan/wwan/ltedongle
https://openwrt.org/docs/guide-user/network/wan/multiwan/mwan3
https://openwrt.org/docs/guide-user/network/wan/wwan/start
https://openwrt.org/docs/guide-user/network/wan/wwan/modemmanager

And the last one from above is for about ModemManager. And I thought this
would be something that I can use instead of the modem provider version of
CM. But from the menuconfig, the ModemManager is not found at all. Maybe
it's because of my OpenWRT is out-dated?
I will try to find it from the latest openwrt.

I am so glad that you are in this mail list.

I want to share the information about my board, modem and openwrt version.
But I am not sure if I can share it in public domain. Maybe it would be no
problem but I will check it with my company first.

Thank you and you have a good day!
Jeonghum
