In an era of rapid advancement in wireless audio technology, the arrival of Bluetooth 5.4 and LE Audio (Low Energy Audio) standards is fundamentally reshaping the audio experience from consumer electronics to professional equipment. Feasycom 's FSC-BT1104QI 블루투스 오디오 모듈, built around the Qualcomm QCC3095 core, is developed as a ready-to-use, easy-to-integrate complete solution, paving the way for developers to access high-end wireless audio applications.

  • Core Features

 

  1. Integration of Classic Bluetooth and LE Audio

The BT1104QI module fully supports the Bluetooth 5.4 사양, with its most revolutionary feature being complete support for LE Audio. LE Audio is not just an upgrade but an entirely new audio architecture. Through the efficient LC3 codec, it significantly reduces power consumption while offering better audio quality compared to the traditional Bluetooth SBC codec.

More importantly, LE Audio introduces Auracast broadcast audio functionality. A single audio source can broadcast to countless headphones or speakers simultaneously, enabling unprecedented applications such as museum guides, airport lounge TV audio sharing, and speech-assisted hearing.

 

  1. Full Range of Audio Codec Support

For applications demanding ultimate audio quality, BT1104QI supports a variety of audio codecs:

Qualcomm aptX series: Including aptX Adaptive (adaptive low-latency, high-quality audio) and aptX HD (high-resolution audio), ensuring the best wireless audio experience for Android devices.

LDAC: Supports bitrates up to 990 KBPS, meeting the needs of audiophiles.

AAC: Provides high-quality, efficient audio transmission for Apple iOS devices.

SBC: Ensures broad compatibility with all Bluetooth devices.

 

  1. 인터페이스

The module is powered by the Qualcomm QCC3095 chip, which integrates a 240 MHz high-performance Kalimba DSP, offering ample processing power for complex audio algorithms. Its rich interface options provide great design flexibility:

오디오 인터페이스: I²S digital audio interface for high-quality lossless audio data transmission; analog microphone input.

Control and data interfaces: UART (for AT command control), USB 2.0, I²C/SPI, 등., facilitating connectivity with host MCUs and other peripherals.

  • Application-Specific Requirements

 

Requirement 1: Consumer expectations for Bluetooth audio have shifted from “audible” 에게 “high-quality.”

The LDAC and aptX HD codecs provide music enthusiasts with high-definition wireless audio experiences of up to 24-bit/96 kHz, fully meeting the demand for superior audio quality.

 

Requirement 2: Connection Stability and Broad Compatibility

The module ensures reliable and robust connectivity in diverse environments, backed by its support for the latest Bluetooth 5.4 사양. 뿐만 아니라, it offers exceptional compatibility across a wide range of devices and platforms, thanks to its comprehensive support for both Classic Bluetooth and LE Audio standards, as well as a complete suite of audio codecs including SBC, AAC, aptX series, and LDAC. This guarantees a consistent and high-quality user experience, whether connecting to smartphones, tablets, 컴퓨터, or other audio sources.

 

Requirement 3: 오디오

The module supports LE Audio, enabling devices to receive broadcast audio via Auracast. Leveraging Auracast, a single transmitter (예를 들어, a tour guide’s microphone) can broadcast to countless receiving headphones within an area, making it ideal for applications like group tours, classroom hearing assistance, and group fitness classes. 또한, LE Audio’s Multi-Stream Audio feature allows a single headset to connect to both a phone and a computer simultaneously, seamlessly switching audio between the two devices without the hassle of manual reconnection.
