OrangePi4G-iot how to enable SIM modem?

lvleeuwen

I am attempting to connect to my SIM card on an OrangePi4G-iot with Linux running on it.

I have ModemManager installed, but when I have it list the modems, it says it can't find any. How do I get the modem connecting to the sim to come up?

Somewhere else I found that the files modem_1_ltg_n.img and modem_1_lwg_n.img, located in /etc/firmware should handle the sim card connection. Is this correct? If so, how can I run them?

Do I need to setup any GPIO specifically for this?
