# OpenThread Sleepy Device Example
|
|
|
|
The example demonstrates the Thread Sleepy End Device (SED), the device will enter [Light Sleep mode](https://docs.espressif.com/projects/esp-idf/en/latest/esp32c6/api-reference/system/sleep_modes.html#sleep-modes) during idle state.
|
|
## How to use example
|
|
|
|
### Hardware Required
|
|
|
|
* Prepare an 802.15.4 SoC development board as an OpenThread Sleepy End Device (SED).
|
|
* Connect the board using a USB cable for power supply and programming.
|
|
* Choose another 802.15.4 SoC as the OpenThread Leader.
|
|
|
|
## Configure the Openthread Dataset
|
|
|
|
* Run [ot_cli](../ot_cli/) on another 802.15.4 SoC device to create openthread dataset configuration and start an openthread network as the leader.
|
|
* Configure the Openthread dataset using `idf.py menuconfig` in `Component config ---> Openthread ---> Thread Operation Dataset`, ensuring that the openthread sleepy device's dataset matches the dataset of the leader.
|
|
|
|
### Build and Flash
|
|
|
|
Build the project and flash it to the board. Use the following command: `idf.py -p <PORT> erase-flash 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.
