Testing a Wireless IoT Product: Things We Wish Someone Told Us Before

Discover key insights for testing wireless IoT products in this informative conference talk by Andreas Müller and Reto Schneider from Gardena (Husqvarna Group). Learn about the challenges and solutions in automated testing using physical devices, with a focus on Zephyr-based implementation of a proprietary sub-GHz wireless protocol. Explore techniques for shielding testbeds from RF interference and reintroducing it deterministically. Gain valuable knowledge on hardware tools, including cost-effective alternatives to expensive test equipment. Delve into the software aspects of IoT testing, covering Zephyr's useful features, pytest implementation for physical device testing, and the application of open-source tools like GNU Radio and Scapy. Understand how to overcome the complexities of testing physical products in noisy RF environments using various tools and open-source solutions, making the process more accessible for developers and testers in the IoT field.
