Hi,

Have you checked this?
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/include/supl_os_client.html

The SUPL client library is released under a different license than the nRF Connect SDK. Therefore, you must download and install it separately to be able to use this module. Before you download the library, read through the license on the webpage. You must accept the license before you can download the library.

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/supl/ folder. Make sure to maintain the folder structure that is used in the zip file.

That zip file doesn't exist on DK downloads so I think you have to contact your Regional Sales Manager if you want the library.

Regards,
Tero

Hi Bala,
Please make sure you are using the latest modem firmware version.
You may also need to add these two configs in your prj.conf:

CONFIG_LTE_NETWORK_MODE_NBIOT_GPS=y
CONFIG_LTE_LEGACY_PCO_MODE=y

Best regards,
