All notable changes to this project are documented in this file. See also Limitations for permanent limitations.
The callout function
nrf_802154_energy_detected()now takes a parameter of type
nrf_802154_energy_detected_tand provides the ED result in dBm. This change in public API can be enabled by setting the
NRF_802154_ENERGY_DETECTED_VERSIONto 1. (KRKNWK-17141)
Include files with API common for both driver and serialization interfaces are now available in the
commondirectory. This change only affects users who are not using the CMake build system. (KRKNWK-17186)
nrf_802154_timestamp_phr_to_shr_convert()that can be used to convert the timestamps used by the driver to the timestamp of the first symbol of frame’s PHR. (KRKNWK-17153)
Added support for
nrf_802154_pan_coord_get()through serialization (disabled by default via
Added the possibility to perform multiple CCA attempts before a delayed transmission in case the first CCA attempt detects busy channel. (KRKNWK-17304)
Fixed an issue causing CSMA/CA procedure to not be terminated correctly in certain Wi-Fi Coexistence scenarios. (KRKNWK-17422)
Fixed an issue causing data corruption when transmitting frames and ACKs containing IE elements. (KRKNWK-17627)
Fixed an issue causing an incorrect driver state after transmission setup failure resulting in failing subsequent calls to the 802.15.4 driver. (KRKNWK-17628)
Changed the value of
4for the nRF5340 and nRF52833. (KRKNWK-16902)
Improved the modulation filtering when using an external power amplifier on the nRF5340, fixing potential certification issues. (KRKNWK-16949)
Removed deprecated functions
nrf_802154_wifi_coex_disable()and accompanying configuration option
Improved frame filtering routine which reduces the likelihood of encountering
NRF_802154_RX_ERROR_RUNTIMEerror during heavier loads. (KRKNWK-15525)
Delayed transmissions and receptions are triggered by a hardware timer what makes them more immune to software latencies. (KRKNWK-8615)
Fixed an issue causing the notification about transmission failure to be generated twice what led to a crash on the nRF5340 network core. (KRKNWK-16825)
Fixed an issue with the receive filter, which led to the receiver not being able to receive a frame shorter than 5 bytes in promiscuous mode. (KRKNWK-16977)
NRF_802154_DISABLE_BCC_MATCHINGconfig option. Setting this option to
NRF_802154_DISABLE_BCC_MATCHING=1had been not functional for multiple releases. (KRKNWK-15525)
NRF_802154_TX_STARTED_NOTIFY_ENABLEDconfig option. (KRKNWK-16364)
The total times measurement feature is turned off. (KRKNWK-16189)
NRF_802154_TOTAL_TIMES_MEASUREMENT_ENABLEDconfig option and support for the total times measurement feature. (KRKNWK-16374)
CSL Phase is calculated assuming that provided CSL anchor time points to a time where the first bit of MAC header of the frame received from a peer happens. (KRKNWK-16647)
Added the possibility to disable the continuous and modulated carrier functions by setting the
The CSL phase calculation method now depends on the anchor time instead of the nearest scheduled reception window. (KRKNWK-15150)
Implemented a workaround for the YOPAN-158 errata for nRF5340. (KRKNWK-15473)
Fixed an issue where the channel for the delayed transmission on the nRF5340 SoC when passing NULL metadata would be set to 11. This was inconsistent with the behavior on nRF52 Series’ SoCs and the channel now defaults to the value in the Personal Area Network Information Base (PIB). (KRKNWK-13539)
Fixed an issue causing the calculated CSL phase to be too small. (KRKNWK-13782)
Fixed an issue causing the nRF5340 SoC to prematurely run out of buffers for received frames on the application core. (KRKNWK-12493)
Fixed an issue causing the nRF5340 SoC to transmit with minimum power when the requested transmit power was greater than 0 dBm. (KRKNWK-14487)
Reworked the implementation of the internal timer to support 64-bit timestamps. (KRKNWK-8612)
The transmit power is now expressed as antenna output power, including any front-end module used.
The transmit power can be set for each transmission request through the transmit metadata. (KRKNWK-13484)
The use of runtime gain control of the front-end module is now provided by the MPSL library. (KRKNWK-13713)
Fixed a stability issue where switching the GRANT line of the coexistence interface could cause a crash. (KRKNWK-11900)
Fixed an issue where the setting
NRF_802154_DELAYED_TRX_ENABLED=0would make the build fail.
Fixed an issue where the CSMA-CA procedure was not aborted by pending operations with higher priority.
Fixed an issue where a notification about an HFCLK change could be delayed by a high priority ISR and could cause a crash. (KRKNWK-11466)
Fixed an issue where canceling a delayed time slot (for CSMA-CA, delayed transmission, and delayed reception operations) after the preconditions were requested could cause a crash. (KRKNWK-13175)
Fixed an issue where a coexistence request would not be released at the end of the time slot while operating in multiprotocol mode.
Fixed an issue where the reported ED values with temperature correction were imprecise. (KRKNWK-13599)
Disabled the build of CSMA-CA when using the open-source service layer.
Removed the files
Delayed transmission and reception feature support for nRF5340. (KRKNWK-12074)
Backforwarding of transmitted frames to support retransmissions through serialization for nRF5340. (KRKNWK-10114)
Serialization of API required by Thread 1.2 (KRKNWK-12077) and other API for nRF5340.
Fixed an issue where interleaving transmissions of encrypted and unencrypted frames could cause memory corruption. (KRKNWK-12261)
Fixed an issue where interruption of a reception of encrypted frame could cause memory corruption. (KRKNWK-12622)
Fixed an issue where transmission of an encrypted frame could transmit a frame filled partially with zeros instead of proper ciphertext. (KRKNWK-12770)
Fixed stability issues related to CSMA-CA occurring with enabled experimental coexistence feature from Multiprotocol Service Layer. (KRKNWK-12701)
Incoming frames with Header IEs present but with no payload IEs and with no payload do not need IE Termination Header provided anymore. (KRKNWK-11875)
Fixed an issue where the notification queue would be overflowed under stress. (KRKNWK-11606)
Fixed an issue where
nrf_802154_transmit_failedcallout would not always correctly propagate the frame properties. (KRKNWK-11605)
Adopted usage of the Zephyr temperature platform for the RSSI correction.
Support for the coexistence feature from Multiprotocol Service Layer.
Support for nRF21540 FEM GPIO interface on nRF53 Series.
Modified the 802.15.4 Radio Driver Transmit API. It now allows specifying whether to encrypt or inject dynamic data into the outgoing frame, or do both. The
nrf_802154_transmitted_frame_props_ttype is used for this purpose.
Fixed an issue where it would not be possible to transmit frames with invalid Auxiliary Security Header if
CONFIG_NRF_802154_ENCRYPTIONwas set to
Fix an issue with the IE Vendor OUI endianness. (KRKNWK-10633)
