NRF9160 Registration times

[Thomas]

Hi,

In the cops=0 state, how long does the modem take to scan each band of both cat-m1 and NB-IoT? How does a roaming sim affect these times for both technologies? In other words, how long should we be waiting to connect with all bands enabled before deciding there isn't a network available in the area, and powering down to save energy?

Unfortunately, I do not have any numbers for the time this can take.

You can greatly reduce the time for the band search by locking the modem to only search on specific bands using AT%XBANDLOCK.

You can test this out by running the at_client sample with the LTE Link Monitor.

How did you do your test?
