ESP-IDF Eddystone Example

This example demonstrates Eddystone-compatible BLE scanning of eddystone frame, including UID and URL.

Eddystone is an open beacon protocol specification from Google aimed at improving “proximity-based experiences” with support for both Android and iOS smart device platforms.

How to Use Example

Before project configuration and build, be sure to set the correct chip target using:

idf.py set-target <chip_name>

Hardware Required

• A development board with ESP32/ESP32-C3/ESP32-H2/ESP32-C2/ESP32-S3 SoC (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.)
• A USB cable for Power supply and programming

See Development Boards for more information about it.

Build and Flash

Run idf.py -p PORT flash monitor to build, flash and monitor the project.

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
