The technical sharing related to MQTT will come to a close, and updates on the latest developments regarding MQTT will be provided periodically. Of course, if there are any aspects of MQTT that have not been thoroughly covered or if you have better suggestions, feel free to leave a comment. We will normally supplement based on everyone’s feedback, and we welcome active participation!!!
Since the end of April until now in mid-June, I have focused on the MQTT communication technology for over a month, primarily because the Internet of Things (IoT) is one of the continuously evolving technological directions. In the industrial sector, the Industrial Internet of Things (IIoT) cannot be overlooked, especially for companies that regard data and digitalization as part of their future business strategy or individuals who consider the IoT as one of the engines for their work development. Therefore, it is worthwhile to pay close attention to MQTT, and of course, communication and exchange are welcome.
