# ESP32 SDK for LiveKit

![API Reference](https://img.shields.io/badge/API_Reference-blue?link=https%3A%2F%2Flivekit.github.io%2Fclient-sdk-esp32%2F)
![Latest Release](https://img.shields.io/github/v/release/livekit/client-sdk-esp32?include_prereleases&label=Release)
![CI Status](https://img.shields.io/github/actions/workflow/status/livekit/client-sdk-esp32/ci.yml?label=CI)

[![Component Registry](https://components.espressif.com/components/livekit/livekit/badge.svg)](https://components.espressif.com/components/livekit/livekit)
[![CI Status](https://img.shields.io/github/actions/workflow/status/livekit/client-sdk-esp32/ci.yml?label=CI)](https://github.com/livekit/client-sdk-esp32/actions/workflows/ci.yml)

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

> [!WARNING]
> [!IMPORTANT]
> This SDK is currently in Developer Preview mode and not ready for production use.
> There will be bugs and APIs may change during this period.
> There may be bugs and APIs are subject to change during this period.

## Features

- **Supported chipsets**: ESP32-S3 and ESP32-P4
- **Supported chips**: ESP32-S3 and ESP32-P4
- **Bidirectional audio**: Opus encoding, acoustic echo cancellation (AEC)
- **Bidirectional video**: *video support coming soon*
- **AI Agents**: interact with agents in the cloud built with [LiveKit Agents](https://docs.livekit.io/agents/)
- **Real-time data**: data packets, remote method calls (RPC)

## Examples
## Getting Started

One of the best ways to get started with LiveKit is by reviewing the examples and choosing one as a starting point for your project:
Before you begin, please ensure you have ESP IDF v5.4 or higher installed on your system (see installation guide for [macOS/Linux](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/get-started/linux-macos-setup.html) or [Windows](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/get-started/windows-setup.html)).

### [Voice AI Agent](./examples/voice_agent/README.md)
### Examples

Conversational AI voice agent that interacts with hardware based on user requests.
One of the best ways to get started with LiveKit is by reviewing the [examples](./examples) and choosing one as a starting point for your project:

## Basic usage
- [**Voice AI Agent**](./examples/voice_agent/README.md): Conversational AI voice agent that interacts with hardware based on user requests.
- [**Minimal**](./examples/minimal/README.md): Basic example of connecting to a LiveKit room with bidirectional audio.

Once you have chosen an example to be your starting point, create a fresh project from it locally using the following command:

```sh
idf.py create-project-from-example "livekit/livekit=0.3.0:<example>"
```

Substitute *\<example\>* for the example's directory name.

### Installation

In your application's IDF component manifest, add LiveKit as a Git dependency:
If you would like to add LiveKit to your existing application, add it as a dependency using IDF:

```yaml
dependencies:
livekit:
git: https://github.com/livekit/client-sdk-esp32.git
path: components/livekit
version: <current version tag>
```sh
idf.py add-dependency "livekit/livekit=0.3.0"
```

Please be sure to pin to a specific version tag, as subsequent 0.x.x releases may have breaking changes. In the future, this SDK will be added to the [ESP component registry](https://components.espressif.com).
> [!IMPORTANT]
> Be sure to pin to a specific version as shown in the command above, as subsequent v0.x.x releases may have breaking changes.

## API Overview

# LiveKit Example Utilities

Common functionality required for example applications, used by the [LiveKit ESP32 SDK](https://github.com/livekit/client-sdk-esp32) for its examples.

**Important**: this component is intended to reduce boilerplate in examples; it only handles basic use cases and and does not provide robust error handling. Therefore, use in production applications is not recommended.

## Network Connection

Establish a network connection with a single function call, configured via _Kconfig_.

### Supported Interfaces

- [x] WiFi
- [ ] Ethernet (*TODO*)

### Usage

1. Configure network connection method and credentials using _Kconfig_
2. Include the _livekit_example_utils.h_ header
3. Invoke `lk_example_network_connect()` in your application's main function
