Supported Targets	ESP32-C3	ESP32-S3

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
• ESP-IDF Getting Started Guide on ESP32-S3

Example Output

The command and output logs for each test are as follows:

PHY Commands Format

For BLE test, if you want to use fcc_le_tx and rw_le_rx_per legacy commands for tx/rx test, you need to enable ESP_PHY_LEGACY_COMMANDS in menuconfig, otherwise, the new format commands esp_ble_tx and esp_ble_rx are supported.

Troubleshooting
