Microchip Information

3.1.2 Peripheral

BLE Peripheral devices send advertisement packets and accept connection requests from another central device. Connected BLE devices, enable bi-directional data transfer using the profiles and services. There are certain use cases where a connection between the devices (Peripheral & Central) is not essential and advertisement feature (transmit only, no receive) is sufficient.

SDK Setup

Getting Started with Software Development

Note: SDK Setup is mandatory step before users start developing app examples based of Building Blocks.

Tip: It is recommended that new users of MPLAB Code Configurator go through the overview.

Blocks

Create FreeRTOS project and configure BLE stack using MPLAB X Harmony Code Configurator 3
- Create a new MCC Harmony project.
- Configure components like FreeRTOS and BLE Stack
- Init BLE Stack
Adding UART
- Print Hello World
Legacy Advertisments
- Transmit Data Payload using BLE Legacy Adv(no BLE connection)
Extended Advertisment
- Transmit Data Payload using BLE Extended Adv(no BLE connection)
Connection
- Configure stack for Peripheral Functionality
- Connection between Peripheral and Central Device
Profiles and services
- Transparent UART Peripheral (Legacy Adv + Connection + Data Exchange)
  - Data Exchange between 2 devices(peripheral and central) after a BLE connection using Microchip Transparent UART profile and service
- Custom Service Peripheral (Legacy Adv + Connection + Data Exchange)
  - Data Exchange between 2 devices(peripheral and central) after a BLE connection using Custom Service
