With the rapid iteration of consumer electronics and smart hardware, ব্লুটুথ অডিও has evolved from “single connection” to “multi-device collaboration, high-definition audio, and low power consumption.” While classic ব্লুটুথ অডিও 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 ডিভাইস, 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, দ ব্লুটুথ Special Interest Group (ব্লুটুথ বলুন) launched the অডিও স্ট্যান্ডার্ড, reconstructing the audio transmission experience with three core features: কম শক্তি খরচ, কম বিলম্ব, and Broadcast Audio.

কোয়ালকম কিউসিসি 3086 chip supports the Bluetooth 5.4 প্রোটোকল, is compatible with a variety of high-definition audio codecs, and features high integration, making it a core component for building next-generation ব্লুটুথ অডিও সমাধান.

Based on this chip, ফ্যাসিককম offers two targeted solutions: দ FSC-BT1114QI ব্লুটুথ লে অডিও transmitter SoC Module and the FSC-BP411 অডিও Bluetooth USB dongle transmitter. তাদের মধ্যে, 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.

অ্যাপ্লিকেশন

  • 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 ব্লুটুথ লে অডিও’s Broadcast Isochronous Stream (বিস) প্রযুক্তি, 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.

ফ্যাসিককম’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. অতিরিক্তভাবে, 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) অথবা এন্টারপ্রাইজগুলিকে LE অডিও ক্ষমতা সহ বিদ্যমান ডিভাইসগুলিকে আপগ্রেড করতে হবে৷ (FSC-BP411 নির্বাচন করুন), তারা একটি উপযুক্ত সমাধান খুঁজে পেতে পারেন.
