With the rapid iteration of consumer electronics and smart hardware, Bluetooth audio has evolved from “single connection” to “multi-device collaboration, high-definition audio, and low power consumption.” While classic Bluetooth audio 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 デバイス, 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, public broadcasting, in-car entertainment, and education and training.

 

To break through industry bottlenecks, Bluetooth 特別関心事グループ (Bluetooth SIG) launched the LE Audio standard, reconstructing the audio transmission experience with three core features: 低消費電力, 低レイテンシー, and Broadcast Audio.

QUALCOMM QCC3086 chip supports the Bluetooth 5.4 protocol, is compatible with a variety of high-definition audio codecs, and features high integration, making it a core component for building next-generation Bluetooth audio solutions.

Based on this chip, Feasycom offers two targeted solutions: の FSC-BT1114QI Bluetooth leオーディオ transmitter SoC Module and the FSC-BP411 LE Audio Bluetooth USB dongle transmitter. その中で, 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.

アプリケーション

  • 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 Audio’s Broadcast Isochronous Stream (ビス) テクノロジー, 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 audio transmitter and receiver.

  • Similarly supports multiple codecs including LC3, SBC, Aptx, aptX-HD, aptX-Adaptive, and aptX-LossLess.

 

Feasycom’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. さらに, 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.
