When working with the nRF 802.15.4 Radio Driver, you should be aware of the following limitations. In addition, see Known issues for temporary issues that will be fixed in future releases.

IRQ priority limitations

Application and device drivers (excluding those compliant with Multiprotocol Service Layer) must not use IRQ priority higher than NRF_802154_SWI_PRIORITY and NRF_802154_SL_RTC_IRQ_PRIORITY.

KRKNWK-11204: Transmitting an 802.15.4 frame with improperly populated Auxiliary Security Header field will result in assert

Workaround: Make sure that you populate the Auxiliary Security Header field according to the IEEE Std 802.15.4-2015 specification, section 9.4.

KRKNWK-12482: Reception of correct frames will occasionally end in failure with error NRF_802154_RX_ERROR_RUNTIME

This issue can occur for the nrf5340dk_nrf5340_cpunet target if a custom application (other than nRF5340: Multiprotocol RPMsg sample or nRF IEEE 802.15.4: Serialization RPMsg sample) is used.
