 The single-chip solution has a combined RFIC (the IEEE 802.15.4 in case of Zigbee) and processor.
 Both the Zigbee stack and the application layer run on the local processor.
+The ZBOSS stack uses the nRF 802.15.4 radio driver directly; no Zephyr networking (L2) layer is used for the radio path.
 
 This design has the following advantages:
