Hi,

Please see %XMONITOR set command. The two last values of the CEREG level 5 response are the ones related to PSM, Active-Time (the time after a transmit event when the device is reachable) and Periodic-TAU (the time between regular transmit events to keep the connection alive).

The meaning of the values can be found in 3GPP TS 24.008, section 10.5.7.4, but long story short, when they start with "111" the timers are not active, i.e. you do not have PSM activated.

You can check if PSM got activated by using AT+CEREG=5 or AT%XMONITOR. If the first three bits of the Active-time or Periodic-TAU is 111, PSM the related timer is not activated.

We know that on Verizon networks only PSM periods of >190 minutes are allowed. That's the reason to refer to that post.

Hi Amanda Hsieh

[quote userid="84523" url="~/f/nordic-q-a/53752/thingy-91-not-getting-gps-data-from-asset-tracker-example"][/quote]

AT%XMONITOR

%XMONITOR: 5,"Verizon Wireless","VzW","311480","0D0A",7,13,"00340902",388,5230,47,28,"","11100000","11100000"

According to this AT%XMONITOR output, am I able to set PSM with my asset_tracker application?

Because looks very familiar to the one from that post that you suggested and I get confused this time, specifically this is the AT%XMONITOR from that post.

%XMONITOR: 5,"Verizon Wireless","VzW","311480","6603",7,13,"018F8B03",68,5230,57,38,"0000","11100000","11100000"

Yes, you should try outside far away from the buildings.
