Hello,
The "nrf_modem_at_cmd"-function is in "nrf_modem_at" library: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/nrf_modem/doc/at_interface.html#initialization
Can it be that you're using the wrong function name?
I believe that method of searching only searches the workspace, ie the folders you have open. I don't think it searches the entire ncs installation.
Hope this helps!
Kind regards,
Torje
Hello
What is the program you are trying to compile? Is it your own or is it a sample?
Perhaps you want to use nrf_modem_at_printf or nrf_modem_at_cmd?
Best regards,
