This document covers the initial environment setup required for developing Matter applications on ESP32 platforms. It details the installation and configuration of ESP-IDF, the Matter SDK, and associated toolchains needed to build and flash ESP32 Matter examples. For information about building and commissioning ESP32 applications, see ESP32 Application Usage Guide. For VS Code-specific development setup, see Visual Studio Code Development (specifically the ESP32 VS Code page). For general Matter build system information, see Building Matter. ESP32 Matter development requires two primary software components: Espressif's ESP-IDF (IoT Development Framework) and the Matter SDK.

The ESP-IDF provides the underlying platform abstraction, RTOS, and toolchain, while the Matter SDK contains the protocol stack and example applications. These components are integrated through build system configurations and environment variables. Sources: platforms/esp32/setup_idf_chip.html1-500 Sources: platforms/esp32/setup_idf_chip.html100-300 Setting up IDF and Matter environment is one time setup. Building the example application requires the use of the ESP-IDF and the xtensa-esp32-elf toolchain for ESP32 modules or the riscv-esp32-elf toolchain for ESP32C3 modules.

The VSCode devcontainer has these components pre-installed, so you can skip this step. Clone ESP-IDF [v5.5.1 release](https://github.com/espressif/esp-idf/releases/tag/v5.5.1 To update an existing esp-idf toolchain to v5.5.1: Please refer the Release Notes to know more about the releases This section talks about setting up ESP-IDF. You should install drivers and support packages for your development host.

Linux and Mac OS-X are the supported development hosts in Matter, the recommended host versions: Additionally, we also support developing on Windows Host using WSL. Development on Windows is supported using Windows Subsystem for Linux (WSL). Please follow the below instructions to set up host. Please setup ESP-IDF and CHIP Environment and refer building and commissioning guides to get started. A prototype application that demonstrates dynamic endpoint with device commissioning and cluster control.

It adds the non-chip device as endpoints on a bridge(Matter device). In this example four light devices supporting on-off cluster have been added as endpoints The Bridge Example makes use of Dynamic Endpoints. Current SDK support is limited for dynamic endpoints, since endpoints are typically defined (along with the clusters and attributes they contain) in a .zap file which then generates code and static structures to define... To support endpoints that are not statically defined, the ZCL attribute storage mechanisms will hold additional endpoint information for NUM_DYNAMIC_ENDPOINTS additional endpoints. These additional endpoint structures must be defined by the application and can change at runtime.

To facilitate the creation of these endpoint structures, several macros are defined: This component contains platform-specific options for the ESP32 platform. variant (Optional, string): The ESP32 mcu/chip to use for this device configuration. One of esp32, esp32s2, esp32s3, esp32c2, esp32c3, esp32c5, esp32c6, esp32c61, esp32h2 or esp32p4. This must match the hardware in use, or it will fail to flash. board (Optional, string): The PlatformIO board ID that should be used.

Choose the appropriate board from this list (the icon next to the name can be used to copy the board ID). This only affects pin aliases and some internal settings; This setting is no longer recommended, variant should be used instead. At least one of board or variant must be specified. If variant alone is specified (the recommended practice), the board configuration will be automatically filled using a standard Espressif devkit board suitable for that variant. Both may be specified (for backwards compatibility) but they must define the same variant. flash_size (Optional, string): The amount of flash memory available on the ESP32 board/module.

One of 2MB, 4MB, 8MB, 16MB or 32MB. Defaults to 4MB. Warning: specifying a size larger than that available on your board will cause the ESP32 to fail to boot. Seeed Studio XIAO ESP32C6 is powered by the highly-integrated ESP32-C6 SoC, built on two 32-bit RISC-V processors, with a high-performance (HP) processor with running up to 160 MHz, and a low-power (LP) 32-bit RISC-V... There are 512KB SRAM and 4 MB Flash on the chip, allowing for more programming space, and binging more possibilities to the IoT control scenarios. XIAO ESP32C6 is Matter native thanks to its enhanced wireless connectivity.

The wireless stack supports 2.4 GHz WiFi 6, Bluetooth® 5.3, Zigbee, and Thread (802.15.4). As the first XIAO member compatible with Thread, it's a perfect fit for building Matter-compliant projects, thus achieving interoperability in smart-home. XIAO ESP32-S3 vs ESP32-C3 vs ESP32-C6: Which One Is Best for Your Project? The RF Switch feature allows you to toggle between the built-in ceramic antenna and an external antenna by configuring GPIO14. To enable this function, you must first set GPIO3 to a low level, as this activates the RF switch control. By default, GPIO14 is set to a low level, enabling the built-in antenna.

To use an external antenna, set GPIO14 to a high level. Refer to the example code below for guidance on configuring GPIO3 and GPIO14 to activate the external antenna:
