Introduction

OneSDK is an integrated development kit for AI applications on the client-side. It provides large language model (LLM) capabilities including voice conversations, text chats, and agents. It also offers device management, supporting interaction with IoT platforms via the MQTT protocol. The SDK is based on libwebsockets to implement protocols like HTTP, WebSocket, and MQTT. It runs on embedded platforms such as Espressif ESP32, FreeRTOS, and uc-OS2, as well as general-purpose platforms like Linux, macOS, and Windows.
