GR551x Bluetooth Low Energy Stack User Guide

2021-03-08
●Purpose:
This document introduces the layers and basic layer functions of a GR551x Bluetooth Low Energy (Bluetooth LE)Protocol Stack. It discusses how applications interact with the protocol stack using APIs on the stack, aiming to enable developers to efficiently use the APIs in developing Bluetooth LE applications.
●Introduction:
The Bluetooth LE software architecture of a GR551x SoC comprises the Application/Profile layer, a Software
Development Kit (SDK), and a BLE Protocol Stack (BLE Stack).
In this architecture, the Application/Profile layer interacts with the BLE Stack through APIs provided by the SDK.
Developers can invoke APIs of GAP, GATT, SM, and L2CAP layers on the BLE Stack during application development.
This document focuses on the composition and functions of the BLE Stack as well as how user applications
interact with the BLE Stack. In addition, the document introduces code examples contained in the GR551x SDK
