BlueSync for Zephyr RTOS

BlueSync is a lightweight and energy-efficient time synchronization protocol designed for Bluetooth Low Energy (BLE) Mesh networks.
It enables accurate, multi-hop synchronization in resource-constrained environments such as linear sensor networks deployed in tunnels or industrial facilities.

This documentation describes the protocol design and implementation within the Zephyr RTOS framework.
