Hi, @XiaoJun-username : Did you download the XDK? audio,UI and AI related functions are extension features. need download by “git clone --recursive --depth=5 [https://github.com/Ameba-AIoT/ameba-rtos.git“](https://github.com/Ameba-AIoT/ameba-rtos.git%E2%80%9C) Also you can refer this link [Realtek Wi-Fi & Bluetooth IoT Online Documentation — SDK Download](https://aiot.realmcu.com/en/latest/rtos/sdk/sdk_download/index.html) ```auto ```
