Supported Targets ESP32-C6 ESP32-H2

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

  • One 802.15.4 SoC (for example ESP32-H2) runs ot_cli example, and forms a Thread network.
  • A second 802.15.4 SoC runs this example.

Configure the project

Set the chip target: idf.py set-target <chip_name>, then configure the project via idf.py menuconfig.

There are two options to configure Openthread Dataset:

  • Auto start mode: Enable OPENTHREAD_AUTO_START under OpenThread Sleepy Example---> Enable the automatic start mode, and configure the dataset under Component config ---> Openthread ---> Thread Operation Dataset.
  • Manual mode: Disable OPENTHREAD_AUTO_START, use the CLI command to configure the dataset and start network.

Build and Flash

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

Configure the Openthread sleepy device

> mode -
> pollperiod 3000
> dataset set active <the same as dataset of the leader>
> ifconfig up
> thread start

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.

Note

Currently, UART wakeup is not enabled. Once the device joins the network as a child and enters sleep mode, the OT CLI will become inaccessible.
