GNSS antenna not able to latch to the satellite

[Ares123]

I am working on project using thenRF9151 board and I require the GNSS functionality to work for the same.
However, my board is not able to latch on to a satellite network even when kept in open environments for large amounts of time.

I used the following sequence of AT commands:

AT%XSYSTEMMODE = 0,0,1,0 // enabling only GNSS

AT+CFUN=31

AT#XGPS=1,0,0,0 //indefinite timeout

And I'm getting the following output:
#XGPS: 1,1

Its not progressing further.

Can someone please help in establishing a GNSS connection?

Hi

Please share some details on what SDK version you're using and what project you're using to reproduce this issue on your end. 

If it's the GNSS sample, please follow the testing section of the sample and please show what it outputs.

Best regards,

Simon

Hi
I am using nRF Connect for Desktop v5.2.0.
Right now, before flashing any customized firmware to the board for the project, I am just trying to using the GNSS functionality to get the location details, etc. from it.

Its not a GNSS sample that I am using as of now, I am just flashing the SLM firmware and using basic AT commands to enable the GNSS functionality. (The sequence of AT commands used is given in the above post)

Please let me know further steps.

Thanks!

Hi Parth

nRF Connect for Desktop is the desktop app you're running, the nRF Connect SDK is only at v3.0.1 yet, so there should be a different version of the SDK and toolchain you're running (probably in VS Code).

Best regards,

Hellow, Simon. I think I have the same problem. When using the “Quick Start” (v1.3.0), I chose the AT Commands option and it downloads the 2.0.2 version of the Modem core. I tested for 30 minutes outdoors with the commands Ares posted and did not manage to get a fix. When testing the NRF CONNECT in VS Code, I chose the GNSS sample (the cellular commands one, not the Zephir) and managed to connect.
