ESP-IDF Gatt Server Service Table Example

This example shows how to create a GATT service with an attribute table defined in one place. Provided API releases the user from adding attributes one by one as implemented in BLUEDROID. A demo of the other method to create the attribute table is presented in gatt_server_demo.

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/ESP32-C3/ESP32-H2/ESP32-C2 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.
