In an OpenThread application, how can one shut down/power on all IEEE 802.15.4 radios during runtime?

Thanks Marte!
In our needs, we need to turn off all the radios not just for reducing power cycles; therefore, using nrf_802154_init() and nrf_802154_deinit() is suitable for us.
Additionally, we can also try utilizing nrf_802154_sleep() and nrf_802154_sleep_if_idle(). If there are any other questions, I'll keep in touch.
Thanks again for your reply!

Hi,

You can use otThreadSetEnabled() to enable or disable Thread:

// Enable
otThreadSetEnabled(GetInstancePtr(), true);

// Disable
otThreadSetEnabled(GetInstancePtr(), false);

For the nRF 802.15.4 radio, you can use nrf_802154_init() and nrf_802154_deinit() to enable or disable the radio, or you can make the radio enter sleep mode with nrf_802154_sleep() or nrf_802154_sleep_if_idle(). With the latter, you do not have to do time-expensive deinitialization and initialization of the radio.
For example:

Depending on how long the radio will be powered off, it might be better to use Thread sleepy end device instead. With this, the device will sleep most of the time, and the radio will sleep when idle. With this, the device will stay connected to the Thread network so that it does not have to connect every time it wakes up to send or receive anything. For more information, see Sleepy End Device types in Thread.

Marte

Hi,

I have started looking into your problem and will get back to you on Monday.
