Using RAIL for IEEE 802.15.4 Applications with EFR32#

Note: This section replaces AN1365: Using RAIL for IEEE 802.15.4 Applications with EFR32. Further updates to this application note will be provided here.

This application note describes how to use RAIL and the Radio Configurator for IEEE 802.15.4 development on EFR32 Wireless parts. It includes supported features and limitations, using the Radio Configurator and supplied software components, and examples.

Proprietary is supported on all EFR32FG devices. For others, check the device's datasheet under Ordering Information > Protocol Stack to see if Proprietary is supported.

Overview#

RAIL provides numerous hardware-accelerated IEEE 802.15.4 compliant MAC features, such as format filtering, address filtering, Auto-ACK, and frame-type filtering.

Silicon Labs provides some fully IEEE 802.15.4-compliant PHY configurations, but not all that is defined by the standard. It is possible to define additional PHYs in the Radio Configurator that are fully or just partially compatible with the IEEE 802.15.4 standard supporting these MAC features.
