Guide for creating custom BLE service with Zephyr

[s23]

Greetings

I am looking for a conceptual guide to adding my own services to the BLE stack, with Zephyr. Is there any documentation or guide for this? I am working on the nrf5340.

Hi
I think the following is a good guide for this: 

lesson 4 of Bluetooth course in the Nordic DevAcademy cover data exchange, and services. 
https://academy.nordicsemi.com/courses/bluetooth-low-energy-fundamentals/lessons/lesson-4-bluetooth-le-data-exchange/

Then I suggest to do all the exercises
 
in particular, Exercise 1 is about 
"In this exercise, we will learn how to create our own custom service and characteristics. We will practice using the GATT API in nRF Connect SDK, which is again based on Zephyr RTOS, to create and add services and characteristics to our board’s GATT table."

hope it helps
