SIM7600 responds with internal error
I have a SIM7600 that I have used successfully with ModemManager but am having difficulties with at the moment. I ran MM with --debug and noticed the following "internal error". I don't know that this is fatal but thought it worthwhile to raise here in case it leads to a fix:

I tried a
--simple-connectand it aborted due to another internal error.

@tve can you run qmicli's --nas-get-system-info and --nas-get-system-selection-preference for me?
-
Sure! I ran MM with debug and issued the simple-connect. Verified that it ended in the internal error shown in the original post. Then ctrl-c'ed MM to run qmicli below. Running qmicli while MM is still running doesn't work. NB: I could give you SSH access to this box if you think that would be useful. Would probably take a day or two. If you happen to run a tailscale vpn client it would be easier. LMK.
