With the rapid iteration of consumer electronics and smart hardware, Audio Bluetooth has evolved from “single connection” to “multi-device collaboration, high-definition audio, and low power consumption.” While classic Audio Bluetooth 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 прылады, 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, а Bluetooth Special Interest Group (Bluetooth Гаварыць) launched the Аўдыё стандарт, reconstructing the audio transmission experience with three core features: Нізкае спажыванне электраэнергіі, нізкая затрымка, 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 Audio Bluetooth рашэнні.

Based on this chip, Feasycom offers two targeted solutions: а FSC-BT1114QI Bluetooth le Audio transmitter SoC Module and the FSC-BP411 Аўдыё Bluetooth USB dongle transmitter. Сярод іх, 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.

Прыкладанне

  • 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 (BIS) тэхналогія, 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.

FSC-BP411 LE Audio Bluetooth USB Dongle

  • Design of 34.4mm×16.7mm×9mm for easy portability.
  • Падтрымлівае Bluetooth 5.4, with backward compatibility for Bluetooth 5.3/5.2/5.1/5.0/4.0/3.0/2.1/2.0.
  • Driver-free support for Windows/Аndroid/iOS/ЧarmonyOS.
  • Supports LE Audio/HFP/A2DP protocols, і больш.
  • Can be used with Bluetooth speakers, гарнітуры, Мабільныя тэлефоны, tablet PCs, and other devices.
  • LE Audio operates in Broadcast Synchronous Stream (BIS) метад, supporting multiple LE Audio headphones without a specific limit on the number.
  • Transmission distance of up to 70 метры (Under Interference-Free Conditions).
  • 35ms minimum latency (CIS mode).
  • 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. Дадаткова, 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.
