How to get list of cell towers using EM9293?

IoT Modules MC/EM Series
1

My current approach has been to do at!lteinfo and see all the towers for each band, so I have to set each band individually and then check the towers via at!lteinfo.

Is there a way I can get a full list of all cell towers (just need the EARFCN, PCI) without having to go through each band?

can your AT!LTEINFO show InterFreq (sane frequency) and IntraFreq (different frequency) ?

How about using this?

Yes, my AT!LTEINFO can show interfreq and intrafreq. It mostly matches the information from lite-qmi-nas.

4

then is it ok for your test case?

5

Yes, should work. I guess the more robust test case is to still go through each band and doing AT!LTEINFO or using that lite-qmi-nas
