How to Develop and Use Matter (formerly CHIP) on ESP32
Matter (formerly known as CHIP project) is a unified smart home connectivity standard, initiated and led by the Connectivity Standards Alliance (formerly known as Zigbee Alliance), and jointly developed by a number of leading IoT companies, committed to building a safe, reliable and IoT devices that can be used seamlessly. Matter is designed with safety as its fundamental principle and aims to improve compatibility between smart home products. Espressif joined the Matter program at the beginning of its launch and focused on the ease of developing and using Matter on Espressif SoCs. Espressif engineers recently published a blog on how to easily build Matter applications on ESP32.
The Matter SDK is an open source code library for implementing the Matter specification, which is still under active development. ESP32 has implemented support for it since its release. The ESP32 is the only platform that supports both Wi-Fi and Bluetooth LE connectivity among the platforms that support the Matter SDK. It supports provisioning (initial device configuration) via Bluetooth LE and Wi-Fi SoftAP, and supports business communication via Wi-Fi.
You can try the following example to build a Matter application on the ESP32:
-
- ESP32 all-clusters-app : ESP32 all-clusters-app: Developers can use ESP32-based development boards (including ESP-WROVER-KIT , ESP32-DevKit-C , M5Stack Core1) to try all Matter features on this example ; You can also configure the network and control the device through the Matter controller. all-clusters-app is the default application used by many Matter developers for development and testing.
- Footprint-optimized app: The ESP32 temperature-measurement-app is specially optimized to allow users to analyze the impact of footprint.
The above examples can all be tested with the Matter controller. The Matter SDK provides reference implementations for the following controllers:
