Supported Targets	ESP32-C6

OpenThread Sleepy Device Example

The example demonstrates the Thread Sleepy End Device (SED), the device will enter Light Sleep mode during idle state.

How to use example

Hardware Required

• Prepare an ESP32-C6 development board as an OpenThread Sleepy End Device (SED).
• Connect the board using a USB cable for power supply and programming.
• Choose another ESP32-C6 as the OpenThread Leader.

Configure the Openthread Dataset

• Run ot_cli on another ESP32-C6 device to create openthread dataset configuration and start an openthread network as the leader.
• Configure the Openthread dataset (CONFIG_OPENTHREAD_NETWORK_DATASET) in ot_power_save, ensuring that the device's dataset matches the dataset of the leader.

Erase the ot_storage

If desired, erase the ot_storage by running idf.py -p <PORT> erase-flash before flashing the board to remove previous examples or other project data.

Build and Flash

Build the project and flash it to the board. Use the following command: idf.py -p <PORT> build flash monitor.

Example Output

As the example runs, you will see the log output indicating the initialization and operation of OpenThread, including the device joining the OpenThread network as a Sleepy End Device (SED) and periodic polling of the leader.
