With the rapid iteration of consumer electronics and smart hardware, Bluetooth-аудио has evolved from “single connection” to “multi-device collaboration, high-definition audio, and low power consumption.” While classic Bluetooth-аудио has long supported devices such as headphones and speakers, it has gradually revealed pain points in practical applications: a single source can connect to a maximum of 2 устройства, there is a certain amount of latency, power consumption is relatively high, and compatibility is limited during high-definition audio transmission. These issues are particularly prominent in scenarios such as multi-room audio, общественное вещание, in-car entertainment, and education and training.

 

To break through industry bottlenecks, тот Bluetooth Special Interest Group (Bluetooth СКАЗАТЬ) launched the Аудио стандартный, reconstructing the audio transmission experience with three core features: низкое энергопотребление, низкая задержка, and Broadcast Audio.

Qualcomm QCC3086 chip supports the Bluetooth 5.4 протокол, is compatible with a variety of high-definition аудиокодеки, and features high integration, making it a core component for building next-generation Bluetooth-аудио решения.

Based on this chip, Физиком offers two targeted solutions: тот FSC-BT1114QI Bluetooth LE Аудио transmitter SoC Module and the FSC-BP411 Аудио Bluetooth USB dongle transmitter. Среди них, the FSC-BP411 requires no complex configuration, supports a wide range of scenarios, and delivers stable performance, making it ideal for ordinary users and enterprises to quickly upgrade their Bluetooth audio experience.

Приложения

  • Classic Bluetooth Mode: Point-to-point connection, paired with a single audio receiver, compatible with traditional Bluetooth audio protocols (A2DP/HFP), and widely adaptable to various Bluetooth headphones and speakers.
  • BIS Broadcast Mode: One-way broadcast, based on Bluetooth LE Аудио’s Broadcast Isochronous Stream (БИС) технология, enabling one-to-many, low-latency synchronous audio distribution.
  • CIS Low-Latency Mode: Two-way connection, establishing a stable, low-latency bidirectional link between the аудио передатчик and receiver.

  • Дальность передачи до 70 метры (В условиях отсутствия помех).
  • 35ms minimum latency (CIS mode).
  • Similarly supports multiple codecs including LC3, СБК, aptX, aptX-HD, aptX-Adaptive, and aptX-LossLess.

 

Физиком’s two QCC3086 solutions essentially provide a “full-scenario solution” for the Bluetooth audio industry: they not only address the pain points of classic Bluetooth such as “few connections, high latency, and high power consumption” but also ensure high-definition sound quality through the aptX series of codecs. Additionally, the “module + Dongle” combination covers the entire chain from hardware development to end-user applications. Whether developers need to quickly integrate Bluetooth functionality (choose FSC-BT1114QI) or enterprises need to upgrade existing devices with LE Audio capabilities (choose FSC-BP411), they can find a suitable solution.
