# 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:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
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](https://www.espressif.com/en/products/devkits) 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](https://idf.espressif.com/) for full steps to configure and use ESP-IDF to build projects.
