Klassischer Bluetooth & LE Audio Dual-Mode Solution Based on Qualcomm QCC5181
- Überblick
In the era of continuous innovation in wireless audio technology, Die Qualcomm QCC5181 chip has become a flagship solution for high-performance Bluetooth audio devices with its outstanding performance.
The FSC-BT1058 Bluetooth module is built around the QCC5181 chipset. It is a dual-mode Bluetooth 5.3 module that supports both classic Bluetooth and LE Audio, combining industry-leading audio technology, flexible connectivity, and easy integration, making it an ideal choice for developers and manufacturers building a wide range of wireless audio products.
- Classic Bluetooth Audio + Der Audio
Designed based on the QCC5181 chip, FSC-BT1058 supports dual 240 MHz Kalimba audio DSP, delivering strong audio processing and system control capabilities to efficiently run complex algorithms.
The module’s key highlight is its simultaneous support for LE Audio and classic Bluetooth audio protocols, meeting both current and future demands of audio devices.
In classic Bluetooth mode, the module supports standard audio profiles including A2DP, AVRCP, and HFP, enabling stable music playback, volume control, and phone call functions.
The firmware also supports classic Bluetooth master-slave integration: the module can switch to A2DP Source for transmitting Bluetooth audio, or switch to A2DP Sink for receiving Bluetooth audio signals.
In LE Audio mode, with support for LC3 codec, ISO channels, and Auracast broadcast audio, the module achieves low power consumption, geringe Latenz, and multi-device synchronized playback.
Like classic Bluetooth, the module can switch profiles to act as a BIS Source or BIS Sink.
