Silicon Labs Unveils BG29 Bluetooth LE Wireless SoC for Miniature Devices

Silicon Labs announced its new Series 2 BG29 family of wireless SoCs, designed to bring high compute and connectivity to the smallest form factor Bluetooth Low Energy (LE) devices without compromising performance. A highly efficient, high memory, low-power, and ultra compact SoC designed for secure and high performance wireless networking applications, this new BG29 SoC is ideal for today's most intensive Bluetooth LE applications in wearables, health and medical devices, asset trackers, and battery-powered sensors.

A Californian company that was instrumental in multiple pioneering efforts to run machine learning on-device, particularly for voice recognition, Edge Impulse has agreed to be acquired by Qualcomm, which is aiming to boost its own development ecosystem for edge AI applications. Edge Impulse, founded in 2019 with the mission to streamline the creation of AI and machine learning models in embedded systems, says it will remain open to other platforms, while accelerating integration with Qualcomm devices and development kits.

The next Bluetooth release is expected to be ratified soon. One important new feature is the Unified Test Protocol (UTP) Test Mode for Bluetooth Low Energy, that will complement existing test methods. The UTP Test Mode will additionally enable over-the-air (OTA) controlled device testing, which will simplify measurements of small and highly integrated devices enormously, since no direct wired connection to the tester is needed. Rohde & Schwarz and Ceva, in close cooperation, have developed a solution for this new test mode.
