Can you please share the Linux drivers?
I’m running on Ubuntu 20.04.
I assume your Linux driver supports wwan0 to send data to the host PC over USB3.1.
Could you also provide instructions how to bring up data between the modem & PC? Any connection manager is available for Linux?
The Linux driver is composed by usb serial driver and usbnet driver.
There is no difference with other modules such as EC25, just need to add VID and PID in option.c.
For the usbnet driver, I will provide the qmi_wwan_q.c.
If the RM520N is connected with the Ubuntu, please check the connection and driver installation by lsusb and lsusb -t
