Supported Targets	ESP32-C6	ESP32-H2

BLE Multiple Connection Peripheral Example

(See the README.md file in the upper level 'examples' directory for more information about examples.)

Please check the 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

• At least two development board with ESP32-C6/ESP32-H2 SoC (e.g., ESP32-C6-DevKitC, ESP32-H2-DevKitC, etc.)
• 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.
