Bluetooth 120: Bluetooth LE Development with Zephyr

Overview

This curriculum provides a practical introduction to developing Bluetooth LE applications using Zephyr on Silicon Labs wireless microcontrollers.

The series builds a complete key finder application based on the Bluetooth SIG Find Me Profile, progressing from a simple peripheral device to a fully featured system. Each step builds on the previous one, showing how the different parts of Zephyr and Bluetooth LE fit together in a real application.
