nrf9160 AT%NCELLMEAS reports only 1 cell

Hi,

I do not get any neighboring cells reported using this command. Is one particular state required to receive information regarding neighboring cells?

Ok, thanks for the information.
I have another question regarding the neighboring cell IDs. For the Location APIs there is the  E-UTRAN cell ID, MCC, MNC required. However, NCELLMEAS only returns physical cellID of neighboring cells. How can this be used for Location APIs? 

Thanks. 
Kind regards, 

Manuel

In the webinar Nordic used the API's from the following thread: devzone.nordicsemi.com/.../webinar-on-nrf9160-modem-fw1-3-0

Hi, one more question  Didrik Rokhaug:

Do you mean SIB3 by "mobility SI" or SIB4/5? 

Kind regards,

The answer I got from the modem team was "SIB3 is minimum requirement for neighbor cell measurements. SIB4 includes additional information about intra neighbors but not mandatory for intra measurements. SIB5 (in addition to SIB3) is required for inter measurements."

Your trace had neither.

Hello Didrik Rokhaug

We enabled SIB3 now, but NCELLMEAS still does not work. I sent you another modem trace with activated SIB3. 

Kind regards,
