Hello,
I have been working on mesh the last week. Now I have created a program with a working LPN that reads sensor data. Now I need to make a working Friend Node.
I base my code of the sensor client example and the light switch server. I want the functionality of the sensor client but including friend functionality. however I can't seem to find what enables Friend funcionality on the light switch server.
I use SDK for Mesh V5.0.0
When I try to enable Friend in nrf_mesh_config_core.h and compile it gives these errors. What Do I need to add or what am I missing?

What enables the friend functionality on the light switch server?
And what do I need to implement in the Sensor client program to be able to friend it?
