TSCH@Zephyr: IEEE 802.15.4 SubG IIoT in the Making

Explore the potential of Zephyr's native IEEE 802.15.4 L2 in this informative conference talk. Dive into the TSCH@Zephyr project, which aims to leverage the extensive capabilities of Zephyr's L2 for industrial use cases. Learn about the wide range of supported SoCs, vendors, and PHYs, including SubG support across regional bands and initial support for HRP UWB. Discover how TSCH (Time Slotted Channel Hopping) compares to proprietary standards like WirelessHART and its relevance to wireless industrial automation, TSN, and distributed battery-driven IIoT sensor networks. Examine the current state of TSCH, SubG, and distributed clocks in Zephyr, including challenges faced in implementing a precision TDMA protocol on the TI CC13/26xx driver. Gain insights into related driver API changes and the conceptual work behind precision distributed clocks, which are crucial for various timing-sensitive applications in embedded RTOS environments.
