Advanced Matter Kconfig options

After enabling the Matter protocol and testing some of the samples, you can enable additional options in Kconfig and start developing your own Matter application.

Defining path to project-specific Matter settings

You can use the CONFIG_CHIP_PROJECT_CONFIG Kconfig option to define the path to the configuration file that contains project-specific Matter settings in the form of C preprocessor macros. These macros cannot be altered using dedicated Kconfig options.

Commissioning with NFC

You can configure the Matter protocol to use NFC tag for commissioning, instead of the default QR code.

To enable NFC for commissioning and share the onboarding payload in an NFC tag, set the CONFIG_CHIP_NFC_COMMISSIONING Kconfig option.

Logging configuration

Logging is handled with the CONFIG_LOG option. This option enables logging for both the stack and Zephyr’s Logging API.

Zephyr allows you to configure log levels of different software modules independently. To change the log level configuration for the Matter module, set one of the available options:


CONFIG_MATTER_LOG_LEVEL_WRN is not used in Matter.

Matter shell commands

You can enable the Matter shell library using the CONFIG_CHIP_LIB_SHELL Kconfig option. This option lets you use the Matter shell commands with Matter samples.

See Using CLI in nRF Connect examples in the Matter documentation for the list of available Matter shell commands.

Matter device identification

Matter has many ways to identify a specific device, both mandatory and optional. These can be used for various purposes, such as dividing devices into groups (by function, by vendor or by location), device commissioning or vendor-specific cases before the device was commissioned (for example, identifying factory software version or related features).

Some of these can be configured using the Kconfig options listed below:

  • CONFIG_CHIP_DEVICE_VENDOR_ID sets the device manufacturer identifier that is assigned by the Connectivity Standards Alliance.

  • CONFIG_CHIP_DEVICE_PRODUCT_ID sets the product identifier that is assigned by the product manufacturer.

  • CONFIG_CHIP_DEVICE_TYPE sets the type of the device using the Matter Device Type Identifier, for example Door Lock (0x000A) or Dimmable Light Bulb (0x0101).

  • CONFIG_CHIP_COMMISSIONABLE_DEVICE_TYPE enables including an optional device type subtype in the commissionable node discovery record. This allows filtering of the discovery results to find the nodes that match the device type.

  • CONFIG_CHIP_ROTATING_DEVICE_ID enables an optional rotating device identifier feature that provides an additional unique identifier for each device. This identifier is similar to the serial number, but it additionally changes at predefined times to protect against long-term tracking of the device.

Amazon FFS support

Matter in the nRF Connect SDK supports Amazon Frustration-Free Setup (FFS) that allows Matter devices to be automatically commissioned to the Matter network using the Matter-enabled Amazon Echo device. To enable the FFS support, set the following configuration options to meet the Amazon FFS setup prerequisites:
