EM9191: 5G NSA cell does not show in PLMN scan

IoT Modules MC/EM Series
1

When doing the PLMN scan using EM9191, the 5G NSA cell is not visible in the scan result.

OK

The module is in NSA mode, which is confirmed by this.

OK

Also, when I do data download/upload test then too, I can see that system mode is getting changed to ENDC. So, 5G cell is available.

Please suggest how to see all the 5G cells available in PLMN scan.

I don’t see problem:

OK

Could this be old firmware issue? Also, in your output only 12(NG-RAN) is visible. Is it because in my case, I have 13(ENDC)? I.e the 5G cell is only meant to be secondary cell so not visible in PLMN scan?

no idea, you can double check new FW.

FYI, I am using GENERIC PRI with all band enabled in AT!BAND
