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 devices, 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, öffentliche Rundfunk, in-car entertainment, and education and training.

 

To break through industry bottlenecks, Die Bluetooth Spezialinteressengruppe (Bluetooth Sagen) launched the Der Audio Standard, reconstructing the audio transmission experience with three core features: Niedriger Stromverbrauch, geringe Latenz, 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 Lösungen.

Based on this chip, Feasycom offers two targeted solutions: Die FSC-BT1114QI Bluetooth Le Audio transmitter SoC Module and the FSC-BP411 Der Audio Bluetooth USB dongle transmitter. Darunter, 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.

Anwendungen

  • 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) Technologie, 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 -Sender and receiver.

FSC-BP411 LE Audio Bluetooth USB Dongle

  • Design of 34.4mm×16.7mm×9mm for easy portability.
  • Unterstützt Bluetooth 5.4, mit Rückwärtskompatibilität für Bluetooth 5.3/5.2/5.1/5.0/4.0/3.0/2.1/2.0.
  • Driver-free support for Windows/Android/iOS/HarmonyOS.
  • Unterstützt Le Audio/HFP/A2DP -Protokolle, und mehr.
  • Kann mit Bluetooth -Lautsprechern verwendet werden, Headsets, Mobiltelefone, Tablet -PCs, und andere Geräte.
  • LE Audio arbeitet im Synchronstream von Broadcast (BIS) Modus, supporting multiple LE Audio headphones without a specific limit on the number.
  • Übertragungsabstand von bis zu 70 Meter (Unter störungsfreien Bedingungen).
  • 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. Zusätzlich, 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.
