To use the Client to send Matter commands, run the built executable and pass it the target cluster name, the target command name as well as an endpoint id.
$ ./out/debug/chip-tool onoff on <NODE ID> 1
The client will send a single command packet and then exit.
This demo app illustrates controlling OnOff cluster (Server) attributes of an endpoint and lock/unlock status of door using LED's. For
ESP32-DevKitC, a GPIO (configurable through
main/include/AppConfig.h) is updated through the on/off/toggle commands from the
python-controller. If you wish to see the actual effect of the commands on
ESP32-DevKitC, you will have to connect an external LED to GPIO.
