Hi @lrdrdn
If it's the same, I'll add the modem in the next package release.
@lrdrdn commented on GitHub (Jan 22, 2023):
I copied file 2c7c0800 to 2c7c0801, but modem type & protocol not display properly.
@4IceG commented on GitHub (Jan 22, 2023):
Commands similar, but scripts need fixing anyway. Ok, I will write here when I add the modem.
@4IceG commented on GitHub (Jan 23, 2023):
Hi @lrdrdn , replace with this file and see if it will be better.

@lrdrdn commented on GitHub (Jan 23, 2023):
working correctly

@4IceG commented on GitHub (Jan 25, 2023):
The modem is already added to 3ginfo-lite, with the compilation I am waiting for the update of the modemband package by Cezary.
@pedroo84 commented on GitHub (Jul 25, 2023):
Hello guys, recently I got a RM520N-GL, but it is locked to "mbim" this way I can't access the AT commands to change it to ECM, any idea how can I do this? in order to have read outs on 3g-info?
@4IceG commented on GitHub (Jul 25, 2023):
Hi @pedroo84 , I don't know in the end if you want to use mbim or ecm modem. My modem works in mbim and I'm not complaining. Do you have the kmod-usb-serial kmod-usb-serial-option packages installed?
@pedroo84 commented on GitHub (Jul 25, 2023):
Hi Rafal, actually mbim works with modem manager here too, the problem is that the USBtty port won't show up on my modem, therefore I can't access AT Command and also 3G-Info can't read the data too. Do you think my module needs a firmware update to solve this?
I own other Quectel modems and never encountered such issue.
@4IceG commented on GitHub (Jul 25, 2023):
First of all, uninstall modem manager. Then check if you have the required packages listed above. Finally, set the modem to work in mbim and configure the connection. Important! my packages don't work with MM.
