Company’s Qualification and Analysis Platforms Enabling Development of Next-Generation Bluetooth Audio
Ellisys, a leading worldwide provider of test and analysis solutions for Bluetooth, Wi-Fi®, Universal Serial Bus (USB), and other wired and wireless communications technologies, has announced the availability of qualification testing and protocol analyzer features supporting the latest version of the Bluetooth Core Specification. In January, the Bluetooth Special Interest Group (SIG) approved the adoption of version 5.2 of the Bluetooth Core Specification and at CES in Las Vegas, introduced LE Audio as the next generation in Bluetooth audio. This latest version of the specification defines the underlying isochronous capabilities needed to support audio on the Bluetooth Low Energy (LE) radio. The Bluetooth SIG also released qualification testing documentation and associated requirements based on the updated specification. Tests defined in this documentation are supported by the Ellisys Bluetooth Qualifier™ (EBQ) dual-mode radio controller qualification test system, enabling a Day One qualification of Bluetooth 5.2 radio controllers.
“ While our statement today publicly announces the availability of support for LE Audio and Bluetooth Core Specification 5.2, we’ve actually been engaged since the conceptual phases, enabling radio controller manufacturers and stack developers with early support for test and protocol analysis,” said Mario Pasquali, Ellisys president and CEO. “This involvement included complex updates to our qualification tools and to our analyzer products that allowed our customers to conduct testing and characterizations far in advance of official, public updates to the core specification, related ancillary specifications, and new qualification test requirements. Being engaged, and indeed being ready at the initial stages of development with critical tools significantly compresses the time needed to create reliable, market-ready products and drives better interoperability between devices from different manufacturers. ”
New Specification Addresses Three Major Areas
This latest iteration of the Bluetooth Core Specification defines three major updates for Bluetooth, each aimed for implementation over the Low Energy radio. These include the addition of an isochronous framework, power-versus-signal quality optimizations, and protocol enhancements to enable multi-device access to a common software stack.
Low Energy Audio to Enable a New Wave of Applications and Development
Bluetooth audio has historically operated solely over the Bluetooth Classic (BR/EDR) radio, but with the release of version 5.2, Bluetooth LE will now support traditional BR/EDR audio use cases and enable interesting applications, which are expected to drive development of a new wave of audio products. Making it possible for Bluetooth LE to transfer audio and support these new applications is the addition of LE Isochronous Channels, a complex feature set that underpins LE Audio by providing the framework needed to support features like audio sharing and synchronized multi-streaming. A new codec is added, Low Complexity Communications Codec (LC3), which delivers high quality audio at a bit rate much lower than SBC, resulting, quite importantly, in lower power requirements.
“ The Bluetooth community continues to drive the technology forward to meet evolving market needs and create new opportunities,” said Mark Powell, CEO of Bluetooth SIG. “LE Audio is a prime example. Not only will it enhance the performance of existing Bluetooth audio products, it introduces Audio Sharing, a new audio use case poised to transform the way we experience audio and connect with the world around us. ”
Ellisys Bluetooth Solutions Support
Ellisys Bluetooth test and analysis solutions are used by developers worldwide, including radio and controller manufacturers, IP companies, including software stack creators, makers of consumer electronics, cyber security services, automotive companies, test labs, and others. The company’s solutions include the Ellisys Bluetooth Qualifier (EBQ) platform, and several protocol analyzer tools supporting both Bluetooth radio types – Low Energy and Classic (BR/EDR). EBQ is a comprehensive compliance, validation, and development system for Bluetooth technology, targeting the behaviors of the lower communications layers, including implementation of more than a thousand test cases defined by the Bluetooth SIG. Ellisys protocol analyzers include the ubiquitous Tracker™, Explorer™, and Vanguard™ systems, offering deep features sets designed to meet a variety of customer requirements.
The EBQ is available from stock to Bluetooth SIG-recognized test labs, known as Bluetooth Qualification Test Facilities (BQTF) and Bluetooth Recognized Test Facilities (BRTF), and to Bluetooth SIG member companies involved with radio controller and IP development. Ellisys protocol analyzer systems are available from stock either direct from Ellisys or from authorized distributors worldwide.
