Tuya AVS SDK Library

This topic describes the related dependencies of Tuya AVS SDK, including basic dependencies, network pairing, and multimedia.

Basic libraries

Wi-Fi, Bluetooth pairing, and A2DP support

By default, Tuya AVS SDK uses wpa_supplicant and bluez as the Wi-Fi management tool and Bluetooth protocol stack respectively. If you need to use other management tools and protocol stacks, see the Wi-Fi HAL and BT HAL in the SDK to implement the interfaces.
