Five years of IEEE 802.15.4 Radio HAL & Co.: Challenges, Insights and Lessons Learned José Alamos (HAW Hamburg) https://summit.riot-os.org/2025/wp-content/uploads/sites/20/2025/09/s02-01.pdf --- This presentation revisits the original motivation behind reworking the 802.15.4 stack and takes the audience on a rollercoaster journey of achieving seamless IEEE 802.15.4 integration in RIOT. We will explore the ups and downs of this process, sharing both success stories and setbacks, while showcasing the current state of the Radio HAL and SubMAC. Additionally, we will offer a glimpse into future directions and share valuable lessons learned about designing hardware APIs and navigating community-driven decisions. These insights aim to provide best practices for tackling similar projects. --- José Alamos is a Ph.D. student in Computer Science and a research assistant at the Hamburg University of Applied Sciences. As part of his research, he is designing reliable and low-power LPWAN MAC
