I think this is the most useful and tremendous material among IoT lectures.

Thank you very much.

In the middle, there was a bit of an environment setting problem due to Windows Firewall in MQTT Broker settings, but it was easy after changing MQTT Broker to Raspberry Pi. Thank you.

Learn the most important communication part of the Internet of Things (IoT). You can learn the core contents of the overall communication that transmits, collects, processes, and monitors center data. Through this course, you can design an IoT communication prototype before making a prototype, and use it for various projects and competitions.

Thank you for the informative lecture.^^
It seems that you can try to work by releasing the MQTT firewall on Windows.
I left an article about the firewall in the news (modifying the location of downloading mqttfx and an example of how to receive messages sent from other PCs), so you can refer to it.
I will come back again with a good lecture in the future.

사물인터넷(IoT)에서 가장 중요한 통신 부분을 학습합니다. 센터데이터를 전송하고 수집하고 가공해 모니터링하는 전체적인 통신의 핵심 내용을 학습할 수 있습니다. 본 과정을 통해 시제품을 만들기 전 사물인터넷 통신 프로토타입을 설계할 수 있으며, 각종 프로젝트 및 공모전에 활용할 수 있습니다.
