BLE Current Time Service Example
(See the README.md file in the upper level 'examples' directory for more information about examples.)
This example creates GATT server demonstrating standard Current Time Service.
It advertises support for the Current Time Service(0x1805) as primary service UUID.
It uses ESP32's Bluetooth controller and NimBLE stack based BLE host
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 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.
