Supported Targets	ESP32-C2	ESP32-C3	ESP32-S3

ESP-IDF Periodic Sync Example

This example supports the periodic extended scan to scan the extended advertisement.

To test this demo, we can run the periodic_adv_demo, which can start extended advertisement with supported param.

Please, check this tutorial for more information about this example.

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-C3 SoC, ESP32-S3, ESP32-C2, ESP32-H2 and BLE5.0 supported chips (e.g., ESP32-C3-DevKitC-1, 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.
