How to Use Example

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

idf.py set-target <chip_name>

Test Scenario

ESP32 Module: ESP32-WROOM-32x
IDF version: 7c29a39d6f
Test case
Test APK: LightBlue V1.1.3
Test report

Hardware Required

A development board with ESP32/ESP32-C3/ESP32-C2/ESP32-H2/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.

Troubleshooting

For any technical queries, please open an issue on GitHub. We will get back to you soon.
