Rayson Technology Launches Nordic-Powered Bluetooth LE Audio Module for Headphones, Speakers, and Audio Systems

Wireless communications company Rayson Technology has released a multiprotocol module based on Nordic Semiconductor’s nRF5340 System-on-Chip (SoC). The solution is designed for advanced Bluetooth LE Audio applications in consumer electronics as well as smart home. Measuring just 16.5 by 13.0 by 2.5mm, the BTM-N340X module supports LE Audio and its Low Complexity Communication Codec (LC3) for lower power wireless audio streaming applications.

In 2022, the Bluetooth Special Interest Group (SIG) announced the Auracast extension of the Bluetooth LE Audio specifications, combining audio sharing and broadcast audio into a new term that would make it easier to promote. The audio innovation promises to propel audio streaming forward by letting users share their audio or select from publicly available Auracast wireless audio streams. At Mobile World Congress (MWC) 2023 in Barcelona the technology was demonstrated in a practical manner for the very first time.

Following the publication of the full set of LE Audio specifications by the Bluetooth Special Interest Group (SIG), the industry is now putting together the building blocks that will enabling bringing products supporting the next generation of Bluetooth audio to market. This article explains what is needed and how to support Auracast broadcast audio, a new Bluetooth capability that enables an audio transmitter to broadcast to an unlimited number of nearby Bluetooth audio receivers.
