Thread Sleepy End Device help (CON-1285)

[pavel808]

Hello all,

I have an ESP32-C6 battery-powered device which works as a Thread end device.

I am now exploring the Thread Sleepy Device capabilities (SED or SSED) to preserve battery life.

My device is quite simple. It receives commands over Matter / Thread from time to time from a client / user (non periodically - it could be once every few seconds, or once every few hours). The device on reception of a command then sends data out on a GPIO pin to control another device.

I believe SSED would suit the best in this case?

How can I simply enable this in my build? I don't see options for this via idf.py menuconfig .

I see the flag in the code CHIP_DEVICE_CONFIG_ENABLE_SSED . Would it simply be enough to have this enabled? Or should other parameters be configured? Unfortunately I don't see a proper example on how to use this.

Thanks so much in advance for any help or guidelines.

You should call ConnectivityMgr().SetThreadDeviceType(ConnectivityManager::kThreadDeviceType_SynchronizedSleepyEndDevice) to make a Thread device be an SSED.

@wqx6 Thanks for your reply. Are there other configuration options involved? For polling times etc.
