Summary
👤
Senior🎓
Top SchoolXianjun Jiao is a Senior Researcher based in Ghent with 12 years of R&D experience at the intersection of software-defined radio and wireless systems, currently working on SDR projects at imec. He previously developed RF and wireless firmware at Apple, Microsoft, Nokia and other research labs, and is the author of openwifi—the first open source WiFi chip—demonstrating deep expertise in low-level radio stacks and hardware-software integration. His open-source BTLE work implements BLE packet sniffing and transmission using HackRF/BladeRF, including GFSK modulation and raw-bit packet support, reflecting hands-on SDR and protocol-level skills. Trained as an electrical engineer with doctoral study at Peking University and a BEng from Nankai, he blends rigorous academic grounding with practical industry impact. Colleagues describe him as a pragmatic researcher who turns complex RF theory into reproducible open tools and testbeds.

Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:28 commits in 1 year 3 months
Contributions summary:Xianjun primarily worked on the `btle` repository, focusing on Bluetooth Low Energy (BLE) packet transmission and reception using a Software Defined Radio (SDR) and HackRF/BladeRF devices. They implemented packet format parsing, GFSK modulation, and sample generation for different packet types like RAW, iBeacon, and ADV_IND. Their work included setting frequencies, configuring the HackRF/BladeRF, and transmitting packets.
