Abstract

Client Sdk ESP32 is an open-source Internet of Things (IoT) project. LiveKit Client SDK for ESP32 series chips. Easily enable real-time audio, video, and data for embedded projects. Use this SDK to add realtime video, audio and data features to your ESP32 projects. By connecting to LiveKit Cloud or a self-hosted server, you can quickly build applications such as multi-modal AI, live streaming, or video calls with minimal setup. It is built using C, ESP32. Key capabilities include: Supported chips: ESP32-S3 and ESP32-P4; Bidirectional audio: Opus encoding, acoustic echo cancellation (AEC); Video publishing: H.264 encoding, subscribing coming soon. The complete source code is publicly available on GitHub under the Apache License 2.0, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

Use this SDK to add realtime video, audio and data features to your ESP32 projects. By connecting to LiveKit Cloud or a self-hosted server, you can quickly build applications such as multi-modal AI, live streaming, or video calls with minimal setup.

2. Objective

LiveKit Client SDK for ESP32 series chips. Easily enable real-time audio, video, and data for embedded projects.

This project demonstrates how C, ESP32 can be applied to a real-world Internet of Things (IoT) problem.

3. Key Features / Modules

  • Supported chips: ESP32-S3 and ESP32-P4
  • Bidirectional audio: Opus encoding, acoustic echo cancellation (AEC)
  • Video publishing: H.264 encoding, subscribing coming soon
  • AI Agents: interact with agents in the cloud built with LiveKit Agents
  • Real-time data: data streams, data packets, remote method calls (RPC)

4. Technology Stack

CESP32

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

  • Arduino IDE / PlatformIO or a C compiler (gcc)
  • Target board where applicable
  • Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/livekit/client-sdk-esp32.git
cd client-sdk-esp32
idf.py add-dependency "livekit/livekit=0.3.11"

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

  • Add a mobile dashboard using Blynk or Firebase
  • Store readings in a cloud database for history charts
  • Add alerts via SMS / Telegram when thresholds are crossed

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

  1. Which microcontroller / board and sensors are used and why?
  2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
  3. Where is the sensor data stored and visualised?
  4. How is power consumption managed?
  5. How would you secure the device and its communication?
