Macro Definition Documentation

◆ LEDP

#define LEDP LED_BUILTIN

A CoAP server example specific for W5100S-EVB-Pico board. It has been tested on WIZnet W5100S-EVB-Pico.

Requirements:

Install "https://github.com/earlephilhower/arduino-pico" (also through the Board Manager).
Select "WIZnet W5100S-EVB-Pico" board.

The current light status can be read using:

coap-client-notls -m get coap://192.168.0.99/light

and the light can be set ON or OFF, respectively, by using:

coap-client-notls -m put coap://192.168.0.99/light -e "1"

coap-client-notls -m put coap://192.168.0.99/light -e "0"

Note that on some boards, ON/OFF logic may be inverted.

In addition, this example also acts as client, sending a GET request every second. To receive such requests, start a CoAP server on the remote machine. To test, you may use:

coap-server-notls -v 9
