#include <nrf_802154/common/include/nrf_802154.h>

Changes the radio state to the RADIO_STATE_SLEEP state if the radio is idle.

The sleep state is the lowest power state. In this state, the radio cannot transmit or receive frames. It is the only state in which the driver releases the high-frequency clock and does not request timeslots from a radio arbiter.

Note

If another module requests it, the high-frequency clock may be enabled even in the radio sleep state.

Return values

NRF_802154_SLEEP_ERROR_NONE	The radio changes its state to the low power mode.
NRF_802154_SLEEP_ERROR_BUSY	The driver could not schedule changing state.
