RE: Issues to build GNSS sample while using SUPL server for A-GNSS

Hi Charlie,

Thank you so much for your support, you have been so helpful with your replies.

I managed to have the SUPL server A-GNSS work, apparently I was making two errors:

Error1: Not adding the Extra Kconfig overlay-supl.conf

Error2: Extracting the SUPL client library in the wrong file

Best regards
Saad

Hi Saad,

I did a try then successfully build the GNSS sample with SUPL. Here are the steps.

1) Referring to docs.nordicsemi.com/.../README.html

Downloading and installing

You can download the SUPL client library from the nRF9160 DK product page.

Download the nRF9160 SiP SUPL client library zip file and extract it into the nrf/ext/lib/bin/ folder. Make sure to maintain the folder structure that is used in the zip file.

2) Set building configuration, adding overlay-supl.conf. I also added "CONFIG_GNSS_SAMPLE_SUPL_HOSTNAME="supl.google.com"" as you did.

Here is the building log:

Hi Charlie,

Thanks for your reply,

the only change I did is to configure assitance data to SUPL server as shown:

In matter of building I don't have to run any command visual studio do it for me:

Thanks,
Best regards,
Saad

Hi Saad,

Could you describe the changes you made to the gnss sample and share the whole building log including the building commands used?

Best regards,

Charlie
