RM500U-CNV not working with QCSuper

I’m trying to use QCSuper with RM500U-CNV module. Windows driver was installed and I can see COM ports:

  • Quectel USB AT Port
  • Quectel USB DIAG Port
  • Quectel USB LOG Port
  • Quectel USB NMEA Port

I can use AT Port with Teraterm. But when I try to use QC Super with the DIAG Port, it returned with the following error:
python.exe “qcsuper-master\qcsuper.py” -v --usb-modem COM10 --reassemble-sibs --decrypt-nas --info

Diagnostics port is enabled :
at+qcfg=“usbcfg”
+QCFG: “usbcfg”,0x2c7c,0x0900,1,1,1,1,1,0,0

I did not have this problem with the EG-25G modem. Can someone please help ?

Thanks.

I do not know what the QCSuper is. I guess it can open the DIAG port for Qualcomm modem.
But RM500U-CNV is not Qualcomm Chip and so that you failed to open it.

Dear Bean,
I see. Is there any Quectel 5G modem that uses Qualcomm chip ?

Alternately, is there a tool that I can use to capture the diagnostic port traffic at RM500U ? I’d like to capture the RRC commands.

Thanks.

You could try RM500Q/RM520N those based on Qualcomm chip.

RM500U is an Unisoc Chip you should use the Unisoc tool to catch the log.
