## ESP-IDF GATT SERVER SPP Example
For description of this application please refer to [ESP-IDF GATT CLIENT SPP Example](../ble_spp_client/README.md)
## 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
2022-10-19 03:57:24 -04:00
* A development board with ESP32/ESP32-C3/ESP32-S3/ESP32-C2/ESP32-H4 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.
