# ESP-IDF Periodic Sync Example
|
|
|
|
|
|
|
|
|
|
This example supports the periodic extended scan to scan the extended advertisement.
|
|
|
|
|
|
|
|
|
|
To test this demo, we can run the [periodic_adv_demo](../peroidic_adv), which can start extended advertisement with supported param.
|
|
|
|
|
|
|
|
|
|
Please, check this [tutorial](tutorial/Periodic_Sync_Example_Walkthrough.md) for more information about this example.
|

|
|
|
## 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-C3 SoC, ESP32-S3 and BLE5.0 supported chips (e.g., ESP32-C3-DevKitC-1, 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.
