I am using the Quectel RM502Q-AE module and encountering several issues during operation. Here are the problems I am facing:
- When connecting via the QMI script/MBIM, the connection is not established.
- On running the script, the wwan0 interface does not acquire an IP address at all.
- When trying to activate the PDU context using the command AT+CGACT=1,1, the command fails, and the context does not activate.
- receiving these messages
AT+QCFG=“usbnet”,0
ERROR
AT+QCFG=“usbnet”,2
ERROR
It is abormal. Please check whether the AT command you sent is correct.
Please check
AT+CGDCONT?
AT+QENG="servingcell"
AT+CPIN?
AT+CFUN?
AT+CGACT?

It is not registerred.
I think you need to check the band first.
Whether the band set in the Open5GS is supported by RM502Q-AE.
