Supported Targets ESP32-C6 ESP32-H2

IEEE802.15.4 Command Line Example

This example demonstrates an IEEE802.15.4 Command Line. The IEEE802.15.4 CLI exposes configuration and management APIs via a command line interface.

How to use example

Hardware Required

To run this example, a board with IEEE 802.15.4 module (for example ESP32-H2) is required.

Configure the project

idf.py menuconfig

The example can run with the default configuration. IEEE802.15.4 Command Line is enabled with UART as the default interface. Additionally, USB JTAG is also supported and can be activated through the menuconfig:

Component config → ESP System Settings → Channel for console output → USB Serial/JTAG Controller

Build, Flash, and Run

Build the project and flash it to the board, then run monitor tool to view serial output:

idf.py -p PORT build flash monitor

Now you'll get an IEEE802.15.4 command line shell.
