nrf9160 AT%NCELLMEAS reports only 1 cell

Hi, I sent you a modem trace via private message. I triggered NCELLMEAS multiple times after the connection was established. 

Kind regards, 
Manuel

I have also sent a private message containing a modem trace for the NRF9160DK v0.9.0. It indicates that multiple networks can be found but NCELLMEAS only reports a single cell. I have also tried both before and after connecting to the network, without any change.

I have moved my test setup around a bit and I can report that indeed I get a single neighbor, but only sometimes, even when in open air. From the webinar from today I understand that the cells your can find using this functionality depends on some configuration of your network provider and may depend on the country you are active in.

It would be great to get cells from all networks from the various providers active in your country. In my case I would get at least 3 cells at any time in The Netherlands.

I have now sent you the modem trace in private message. 

Hi, and thanks for all the traces.

We see that the documentation for the command is a bit thin, and are working on improving it.

user101994: In your trace, the first NCELLMEAS is issued while in RRC connected and there are no measured neighbors available thus only own cell is reported.
Second NCELLMEAS is issued while in RRC idle but again no neighbors available.

user80090: In your trace, there are no mobility SI broadcasted in cell where NCELLMEAS is issued, only SIB1 and SIB2. In this case neighbor measurements are not possible.

And for completeness, in my test the first NCELLMEAS is issued while UE is in RRC connected mode and connected mode measurements are not configured. Results are available only from own cell.
Second NCELLMEAS is issued while UE is in RRC idle but mobility is not configured on cell by network (only SIB2 scheduled). Neighbor measurements are not possible, thus results are available only from own cell.
