In the Bluetooth audio product market. The Qualcomm platform is the high-end choice in this field. As an indicator to lead the direction of market development. Recently, Qualcomm S7 Pro Gen1 is the first new generation flagship platform that combines high-performance, low-power computing, end-side AI and advanced connectivity. Start a new era of audio innovation and create a breakthrough user experience. Setting a new benchmark for high-performance audio with ultra-low power consumption.

The first-generation Qualcomm S7 and S7 Pro platforms leverage unmatched levels of end-side AI to deliver advanced, personalized, and responsive audio experiences.

The new platform delivers 6 times the computing performance and nearly 100 times the AI performance of its predecessor, and brings a whole new level of ultra-flagship performance with low power consumption.

The Qualcomm S7 Pro is the first audio platform to support Qualcomm Extended Personal Local Area Network (XPAN) technology and ultra-low power Wi-Fi connectivity, extending the audio transmission distance in the home, building or campus, and supporting lossless music quality up to 192kHz.

Quan Ding Group also launched the Qualcomm S7 Pro Gen 1 platform TWS headset solution at the fastest speed for customers to choose applications.

The S7 Pro platform consists of two ics, QCC7226 and QCP7321. Among them, QCC7226 is the main control running user application, Bluetooth protocol,DSP audio data processing,AI algorithm platform. The QCP7321 provides WIFI transmission as a coprocessor and sends and receives master data through the SPI interface.

FAQ

1. What is special about development?

All operations must be performed after activate python venv is selected

2. How do I obtain the ADK doc?

Run the build_all_docs command and view it in the ADK Toolkit directory docs

3. Do you support external flash?

Currently, there is no relevant design support, and the built-in flash can meet most application scenarios

4. Can Wifi be used for other applications?

No, it can only be used as audio transmission. 1. What is special about the development?
