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 enheter, 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 Special Interest Group (Bluetooth SIG) launched the LE Audio standard, reconstructing the audio transmission experience with three core features: låg effektförbrukning, låg latens, and Broadcast Audio.

Qualcomm QCC3086 chip supports the Bluetooth 5.4 protokoll, 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. Bland dem, 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 (Bis) teknologi, 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.
  • Stöder 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/Enndroid/iOS/HarmonyOS.
  • Supports LE Audio/HFP/A2DP protocols, och mer.
  • Can be used with Bluetooth speakers, headsets, mobiltelefoner, tablet PCs, and other devices.
  • LE Audio operates in Broadcast Synchronous Stream (Bis) läge, supporting multiple LE Audio headphones without a specific limit on the number.
  • Transmission distance of up to 70 mätare (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. Dessutom, 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.
