How to include library in nRF9160?

[Yusuke]

I want to include GetWifiAPs.c and GetWifiAPs.h files, which I developed by myself, in my project.

How do you include them?

I'm using SEGGER Embedded Studio.

I include header file(.h) in the following path and I think It is successful.

/Users/username/Documents/nRF9160/ncs/nrf/include

<main.c>

#include "GetWifiAPs.h"

However, when I build and run the project. an error happens.

Hi there,

How do you include them?

All files which are to be included in an nRF9160 project must be included in the CMakeLists.txt

Have a look at the CMakeLists.txt of \samples\nrf9160\lte_ble_gateway. Add your files to the src folder in the samples\nrf9160\uart_2 folder, then add them to the CMakeLists.txt

Kind regards,
Oeyvind
