summary

Zephyr’s native IEEE 802.15.4 L2 now handles SubG, SUN O‑QPSK, FSK, OFDM and initial HRP UWB support and is running TSCH on TI CC13/26xx hardware with a cleaned-up driver, corrected CCA/backoff and channel page handling. A TSCH prototype achieves zero dropped packets over a weekend and schedules radio on/off to cut power while meeting sub-microsecond precision timing for distributed clocks. Work remains on net_time APIs, Linux interoperability and broader UWB (Corvo/Decawave) hardware support.
