nRF 802.15.4 Radio Driver
The nRF 802.15.4 Radio Driver is a set of libraries that implement the IEEE 802.15.4 functionalities for the SoCs from the nRF52 and nRF53 families. The following functionalities are implemented:
Frame transmission.
Frame reception and filtering.
Acknowledgments. It allows sending and receiving acknowledgments according to the protocol specification and the timing requirements. Both
Imm-Acks
andEnh-Acks
are supported.Promiscuous mode.
Low power (sleep) mode.
Carrier transmission. It allows sending a carrier wave continuously, either modulated or unmodulated. This feature can be used for radio tests.
Multiprotocol support. It allows the concurrency of Bluetooth LE and 802.15.4 operations.
CSMA/CA support. It provides a built-in CSMA/CA mechanism, optimized for performance.
Delayed transmission and reception. It allows the scheduling of transmissions and receptions, to execute them at a predefined moment. It can be used for features like CSL, TSCH, and Zigbee GPP.
Timestamping. It provides precise frame timestamps.
PA/LNA. It allows the Radio Driver to control an external PA/LNA module to amplify the RF signal.
The 802.15.4 Radio Driver consists of the following libraries:
802.15.4 Radio Core
802.15.4 Service Layer
802.15.4 Serialization
The libraries are compatible with the following SoCs:
nRF52833
nRF52840
nRF5340
