You can just include the API without config. See NFC: Tag reader sample, which uses APDU reader and writer API.

Thank you, surely I will review the course that covers the SDK configuration.

Since the writable ndef tag example is already working, I believe that my project configuration is already OK.
My difficulties are related to the APDU API.
Is there a small guide to show the philosophy of them? the intended usage?
I am asking this because looking at the automatic documentation you pointed, I understood that it has nothing to do with the writable_ndef api logic. Init functions, callbacks... all different.

So I am stuck.

Do you have some hint?

You can take a look at this course https://academy.nordicsemi.com/courses/nrf-connect-sdk-fundamentals/lessons/lesson-3-elements-of-an-nrf-connect-sdk-application/

Thank you Amanda,

Now the link to the doc has been fixed and I read it: I am seeing that these pages are the usual docs automatically generated from the source code. It is good to have it.
Anyway a simple use case example would be of great help!
Usually, for these kind of application, there should be a setup-config sequence to follow to initialize the peripheral and the involved libraries, and then some method and callbacks to handle the message exchanges....
And, very important, when using nRFConnect SDK, a detailed description of the required CONFIG_XXX=Whatever (to me the prog.conf area is the second most frustrating aspect of the SDK).

Can you kindly share some hint in writing the correct sequence of functions to call?

Hi,

I can open the link in the API documentation for APDU reader and writer
