Bluetooth is 20 years young in short range wireless technology, operating in the ISM band with over 30000 member companies worldwide. Support for Bluetooth in Zephyr OS is present since its initial releases, and a fully open source controller sub-system contributed and released in Zephyr OS v1.6 release in December 2016.

The presentation gives an introduction to Bluetooth Low Energy Controller implementation in the Zephyr OS, covering the aspects of scheduling a radio event, different types of radio events comprising the PHYs, states and roles in Bluetooth Low Energy Controller, and data flow within the controller sub-system.The presentation covers the topics of designing a multi-vendor capable sub-system, a new controller architecture, its implementation, real-time scheduling, maximizing radio utilization, higher overall throughput and an ultra low power race-to-idle execution of code.
