I have an RM520N-GL on an OpenWRT box.
I have enabled the MHI kmods and I can see that the modem is recognized and I get a /dev/wwan0at0 port along with the /dev/wwan0mbim0 and /dev/wwan0qdcm0 ports. If I configure the modem with the MBIM protocol, I can get it online.
I would like to use it in QMI mode for efficiency but I’m not getting the /dev/wwan0qmi0 port. Can anyone assist in understanding what do I need to do to get it working?
Thank you.
