Summary
👤
Senior🎓
Top SchoolTengfei Chang is an Assistant Professor at HKUST (GZ) with 13 years of experience building and standardizing low-power wireless IoT systems across academia and industry. He holds a PhD from the University of Science & Technology Beijing and spent a formative semester at UC Berkeley developing synchronized hybrid networks and later contributing low-level firmware to the widely used OpenWSN platform. At Inria he benchmarked and ported 6TiSCH stacks to novel single-chip micro-motes, authored RFC9033 and repeatedly served as a technical expert for ETSI 6TiSCH plugtests, bridging standards, testing, and implementation. As co-founder and network architect of MonoLets and later Principal Scientist at Butlr, he turned research ideas into product-grade network architectures for high-traffic sensing and real-time tracking. His work uniquely combines protocol design, embedded firmware, and hands-on silicon-scale IoT experience, giving him a rare end-to-end perspective from RF transceivers to Internet standards.

OpenWSN firmware: stuff that runs on a mote
Role in this project:
Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:12 releases, 1871 commits, 396 PRs in 10 years
Contributions summary:Tengfei's contributions focused on low-level firmware development for the OpenWSN platform. They made several modifications to the firmware's timer and radio driver, including implementing a new timer with periodic functionality and integrating the radio with a sub-GHz transceiver (AT86RF215) to enable beacon sending and reception. Further commits included setting up a dedicated cell for minimal communication with the parent node and the implementation of a protocol for traffic adaptation with the parent.
