Yeah that looks good to me. What I would suggest is that you use a sample that sends your location and just take the DK outside with you running on the battery to verify that it works. If it for some reason do not work then we have to dig deeper

Hi runsiv,

yes i followed the steps mentioned, the configs i added should do it i guess

CONFIG_LTE_NETWORK_MODE_LTE_M_GPS=y
CONFIG_MODEM_ANTENNA_GNSS_EXTERNAL=y

CONFIG_MODEM_ANTENNA_GNSS_ONBOARD=n
CONFIG_MODEM_ANTENNA_AT_COEX0="AT%XCOEX0=1,1,1560,1580"

but i guess as you said, since i'm indoors this isn't guaranteed to work.

thank you for your time,

Regards.

Hi Saif

I would presume the issue is that you are inside and even with an external antenna it can be difficult to get GNSS to work indoors. Building material, line of sight issues and other obstacles can be an issue. If possible I would suggest to try to take the DK outside, or at least if it is possible, take it to a windows and try there. When you tested, did you follow the steps found here?
