Silabs CLI Guide#

Introduction#

The guide discusses the different CLIs that can be enabled with the Silabs sample apps. The CLIs expose configuration and management APIs via a command line interface (CLI). For OpenThread devices, the OpenThread CLI can be used with or without the Matter CLI. For Wi-Fi devices, only the Matter CLI is available.

Enable the CLI Interfaces#

Matter CLI#

To enable the Matter CLI, the chip_build_libshell=true argument can be added. This build argument can be added to OpenThread and Wi-Fi build commands. Here is an example of the build command with the Matter CLI enabled.

./scripts/examples/gn_silabs_example.sh ./examples/lighting-app/silabs/ ./out/lighting-app BRD4187C chip_build_libshell=true

OpenThread CLI#

The OpenThread CLI is enabled by default on all OpenThread builds. To disable the OpenThread CLI, the enable_openthread_cli=false argument can be added. Here is an example of the build command to disable the OpenThread CLI.

./scripts/examples/gn_silabs_example.sh ./examples/lighting-app/silabs/ ./out/lighting-app BRD4187C enable_openthread_cli=false

Connecting to the Device#

The different CLIs are provided through the UART interface. The following table exposes the UART configurations to connect to the different CLIs.

Configuration	Value
Baudrate (speed)	115200
Data	8 bit
Parity	None
Stop Bit	1 bit
Flow Control	None

Any serial terminal emulator will permit to connect to the device. For MacOS and Linux, the screen utility can be used. For Windows, Tera Term can be used.

Screen Utility#

To use the Screen utility, we first need to find the vcom port. For MacOS, it will be formatted as /dev/cu.usbmodem... and for Linux it will be formatted as /dev/ttyACM....
Here is an example command connecting to the device with the screen utility.

screen /dev/cu.usbmodem0004403048491 115200 8-N-1

Tera Term#

See the Tera Term guide on how to connect to the device on Windows.

Command List#

When the prompt matterCli> is printed, the device is ready for a command.

Note: When the OpenThread CLI is used without the Matter CLI, the prompt is >.
