Embedded Open Source Summit 2023

Ultra-wideband radio technology, due to its unique physical characteristics, has enabled numerous use cases for systems which require precise distance measurement between some devices. One of these cases is a Real Time Positioning System (RTLS), whose task is to precisely track 3D positions of some objects with a tracker attached. In this presentation, Aleksander presents a open source RTLS solution based on Zephyr RTOS and Decawave's (now Qorvo) MDEK1001 Ultra-wideband devkit. The presentation begins with the generic introduction into RTLS, followed by the description of the designed system. In the second part, Aleksander shares his experience on using Zephyr as a beginner and its unique features that have enabled him to rapidly implement the software for embedded devices. Finally, he'll speak about work that needs to be done to transform the solution into a generic Zephyr module, and how Zephyr facilitates the process of making code portable to numerous hardware platforms.
