GPS activation issues often stem from power management and antenna design. Using reliable components like the XCF32PFSG48C for memory and configuration storage can ensure stable firmware execution and better overall GPS performance.

Hello Jishnu,

I have looked at the error log and it seems like the issues lie on these two

NRF9160_GPS_SET_COEX0=y
NRF9160_GPS_COEX0_STRING="AT%XCOEX0=1,1,1565,1586 configurations.

Maybe you missed to add the prefix CONFIG_ ?

It should look like

CONFIG_NRF9160_GPS_SET_COEX0=y
CONFIG_NRF9160_GPS_COEX0_STRING="AT%XCOEX0=1,1,1565,1586

Besides these you need to set CONFIG_NRF9160_GPS in the prj.conf file.

Could you please try and let me know the outcome?

Hi Kazi,
Attaching the error log here, on building the firmware. Please check. This is when we tried to build the project when adding the configurations to enable COEX0 pin

Hello jishnu,

It seems issue with your custom board as GPS worked on our DK. You need to ensure that COEX0 pin connection is correct on the board and not interrupted by other components. Is the customer board properly powered and the power is flowed to the other components along with GPS module and the LNA.

''Tried to add the configuration in mentioned in the attached link. But on building it was showing build error because these configurations are deprecated. ''

Can you show us the details error log?

Thanks.

Kazi
