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 उपकरण, 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, the Bluetooth Special Interest Group (Bluetooth SIG) launched the LE Audio standard, reconstructing the audio transmission experience with three core features: कम बिजली की खपत, कम अव्यक्ता, and Broadcast Audio.

क्वालकॉम QCC3086 chip supports the Bluetooth 5.4 शिष्टाचार, 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: the FSC-BT1114QI Bluetooth LE Audio transmitter SoC Module and the FSC-BP411 LE Audio Bluetooth USB dongle transmitter. उनमें से, 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.

  • 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 (बीआईएस) तकनीकी, 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.

  • Transmission distance of up to 70 मीटर की दूरी पर (Under Interference-Free Conditions).
  • 35ms minimum latency (CIS mode).
  • Similarly supports multiple codecs including LC3, एसबीसी, 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. इसके अतिरिक्त, 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.
