Introduction

Apple Notification Center Service (ANCS) is applied to intelligent Bluetooth-enabled devices, such as wristbands and smart watches that connect to iOS devices. Through a Bluetooth Low Energy (Bluetooth LE) link, the Bluetooth devices can access media notifications from iOS devices, and send ANCS-related control commands to iOS devices.

This document introduces how to implement ANCS Client based on a GR55xx SoC.
