Thingy:91 not getting GPS data from asset tracker example

[fabocode]

Location: Utah.

Well, I was testing a Thingy:91 board here with the very first boot and test with the iBasis SIM card which comes with the product.

Everything goes well, except that I'm not able to get GPS data in the nRF Cloud, currently in the terminal I can tell that the GPS module is started but the process to find the location is elapsed, just again and again. I've followed the procedure that states that you need to push the button for over 10 seconds until you see a purple LED light from the Thingy 91 but it simply keeps there until is reseted after 360 seconds. 

I've found that I can check if the iBasis SIM card is able to get into PSM mode over some AT commands like AT%MONITOR and AT+CEREG. 

This is the output:

AT+CEREG? +CEREG: 2,5,"0D0A","00340902",7

OK

AT+COPS=3,2

OK

AT+COPS? +COPS: 0,2,"311480",7

OK

AT%XCBAND

%XCBAND: 13

OK

AT+CGDCONT? +CGDCONT: 0,"IP","ibasis.iot","10.160.64.112",0,0

OK

AT+CGACT ?+CGACT: 0,1

OK

AT%XMONITOR

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

OK

From what I can tell, the current information that provides the AT commands says that everything is well. However. I wanted to ask here first before I made any other test (with a new firmware from the product page).

 

I have no tested outsied, is it possible for my signal strenght? do you think that I need anything else to do before I made a firmware update?

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

Please try Didrik Rokhaug's suggestion in this post. 

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"

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.
