nRF9160 dk + serial lte modem + gps

Question

I am using a nRF9160 DK. I'm using a Windows 10 system and setup the SDK using nRF Connect.

I've started to experiment with the serial_lte_modem project -- version 1.3.1 using whatever the default settings are. Once I built the fw, I loaded it to the nRF9160 dk using the programmer tool. I also uploaded the modem fw 1.2.1.

I am trying to get GPS working. I have read through the link: https://devzone.nordicsemi.com/f/nordic-q-a/55578/nrf-9160-serial-lte-modem#permalink=542581

Whenever I try to run one of the GPS commands subsequent commands do not seem to work. For example, one I enter something like:

AT#XGPSRUN?

then any command entered later on has no response. The response given for the gps command doesn't match the other post. I'm not sure how to proceed.

Regards,

Hi fe-hadella The command name was changed in NCS v1.3.x. It is now called AT#XGPS=[,] which you can see here . There have been a number of changes to the command names for the other commands as well in NCS v1.3.x. Here is an example sequence of commands from the boot up of the example: AT%XSYSTEMMODE=0,0,1,0 AT%XMAGPIO=1,0,0,1,1,1574,1577 <-- This command is for DK v0.9.0 AT+CFUN=1 AT#XGPS=1,3 <-- 3 as the mask shows the satellites in view If you have not enabled LTE on the board, then you do not need to go into PSM or eDRX to use GPS. Here is an example of the commands running on my board and obtaining a fix: I was using DK v0.9.0 with modem firmware v1.2.1 and NCS v1.3.1 Regards, Akash
