Infineon has built quite the Bluetooth resume over the years, and with the launch of support for the Zephyr OS in our latest Bluetooth^® LE MCU, the AIROC™ CYW20829, we are opening the door even wider for developers. And with the number of applications growing almost daily, such support is welcome. Applications today include game controllers, PC peripherals, wearables, electronic shelf labels, asset tracking, and automotive applications such as car access, tire pressure monitoring, and battery management systems.

Hello Embedded Engineers, Developers and Makers! Welcome to In Case You Missed it: Embedded Insights, the weekly news show all about Embedded technologies and solutions from Embedded Computing Design.

Bluetooth^® has found its way into far more applications than anyone could have imagined when the spec was first introduced, decades ago. To be fair, the specification has evolved with higher range, more bandwidth, and with less power consumption than what was originally possible, paving the way for all these new and cool applications.

Distance measurements via Bluetooth are getting a big improvement with the upcoming Channel Sounding feature. This explainer video gives a quick, high-level overview of existing Bluetooth distance measurement techniques and the working principles behind the new Channel Sounding feature.

Smart Home is a thorny problem. What is a Smart Home? Nearly every home has Wi-Fi now, and most have additional connected, or IoT-enabled, devices. Whether those be smart locks with cameras, connected light bulbs, power meters and thermostats, or all the way to home hubs or assistants controlling all of the above, Smart Home tech is finally starting to become part of many people’s home life.

Bluetooth Low Energy (LE) is a variation of the Bluetooth wireless standard that’s designed for short-range data exchange with minimal power consumption. Introduced as part of the Bluetooth 4.0 specification, it enables devices like wearables, sensors, and smart home products to operate efficiently on small batteries. Bluetooth LE supports features like quick device discovery, secure connections, and in newer versions (5.0+), extended range, and higher data rates.

Eko Health revolutionized the traditional stethoscope and turned it into an AI-powered disease detection platform. They needed a Bluetooth product that combined high-end processing power with low power, and Infineon's PSoC 63 Bluetooth LE MCU provided exactly that.
