# Certification Test Example
(See the README.md file in the upper level 'examples' directory for more information about examples.)
This example shows how to use the Certification test APIS.
## 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-C3/ESP32-S3/ SoC.
* A USB cable for Power supply and programming
### Configure the project
Open the project configuration menu (`idf.py menuconfig`).
In the `Example Configuration` menu:
* Enable RF certification test functions.
* Disable Interrupt Watchdog.
* Disable Task Watchdog Timer.
### Build and Flash
Build the project and flash it to the board, then run the monitor tool to view the serial output:
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 all the steps to configure and use the ESP-IDF to build projects.
* [ESP-IDF Getting Started Guide on ESP32-C3](https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/get-started/index.html)
* [ESP-IDF Getting Started Guide on ESP32-S3](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/get-started/index.html)
