34th Workshop – Bluetooth: Technology Innovations & Applications

VIRTUAL EDITION – WEBINAR : Tuesday 29 June 2021, 12h30-14h15


In this virtual workshop we will address technology innovations that have been adopted in the latest versions of the Bluetooth standards, such as mesh networking, low-power features, and LE Audio.

Speakers from industry will then zoom in on the possibilities and challenges that these innovations offer for their applications in assets tracking/monitoring, and smart audio systems.

12h40A digital communication twin for managing a QoS-enabled heterogeneous Bluetooth mesh network
Jeroen Hoebeke, Professor, imec-IDLab-UGent
slides (members only, login required)

With the release of the meshing specification, Bluetooth Low Energy made the transition from a star-based topology to a true mesh networking topology, now offering a standardized way to achieve multi-hop communication. Following a short introduction to the Bluetooth Mesh specification, we will present two innovations designed within the ICON BLUESS project, which can turn a smart light mesh backbone into a trustworthy carrier for diverse sensing and actuation devices: QoS extensions for Bluetooth meshing and autonomous network management using a digital communication twin.
