# [W5500] REST API , MQTT 적용

## Question

Asked by park young kyun on 2018-11-28 in Ethernet Chips.

STM32 에 W5500 이나 W5300을 연결하여 사용하려 합니다.

KT IoT Makers 서버와 연동하려 하는데 프로토콜이 Http 로 된 REST API 를 사용합니다.

W5500 이나 5300으로 가능한지요?

안녕하세요

W5500과 W5300은 HW에서 TCP통신 까지 지원합니다.
따라서 HTTP protocol을 SW에서 구현하셔서 사용하시면 가능합니다.

참고하실만한 링크 참조해드립니다.

아래링크는 keil기반의 WIZwiki-W7500 보드로 http client를 구현한 예제입니다. W7500은 W5500이 내장 되어있는 mcu chip입니다.
