uConsole

I’ve received and assembled my uconsole with RPI compute module 4 and 4G module. How do I configure/use it?

uconsole-4g-cm4 enable didn’t work for me :frowning:
When I try to do mmcli -L, I get no modems found…

Okay so after a while it shows the modem but there is an error with the service & the AT command thing does still not work.

Here’s the otput of mmcli:

dave@raspberrypi:~ $ mmcli -L
    /org/freedesktop/ModemManager1/Modem/0 [SIMCOM INCORPORATED] SIMCOM_SIM7600G-H

I should note that I’m not sure the SIM card is active (got 2 with my contract, maybe need to somehow activate the second one first), but the AT commands with the modem should still work, regardless, right?

I just realized: my SIM card is PIN-locked. Could that be the issue? How do I enter my PIN? :smiley:

The setting if the PIN is required, is in the SIM itself. Put it in some barbones/burner cellphone that is reset (so you won’t leave your numbers etc. in there) and go to the respective SIM settings. You should be also seeing some settings regarding the pin. Most likely you will have a switch to disable the sim-pin request. This setting will be written into the SIM itself and from here on out won’t be bothering you until you enable it in the described fashion.

So I was able to enter the PIN, I believe using this command:
sudo mmcli -i 0 --pin=1234

I’ll check my terminal history later and edit if needed.
