It is a message-oriented protocol. Because of this, it is very lightweight and widely adopted in the IoT ecosystem. Almost all IoT … Read more
1. What Is MQTT MQTT (Message Queuing Telemetry Transport) is a lightweight, publish-subscribe based message transport protocol that is suitable for resource-constrained devices and low-bandwidth, high-latency, or unstable network environments. It is widely used in IoT applications, enabling efficient communication between sensors, actuators, and other devices. 2. How MQTT Works To understand how MQTT works, … Read more
IoT (Internet of Things) devices must connect to the internet. By connecting to the internet, devices can collaborate with each other and work with backend services. The foundational network protocol of the internet is TCP/IP. MQTT (Message Queuing Telemetry Transport) is built on the TCP/IP protocol stack and has become the standard for IoT communication. … Read more
Hello everyone, I recently worked on an IoT project and summarized the MQTT protocol. As we all know, the MQTT protocol is widely used in the IoT field. If you are not familiar with it yet, I believe this article can help you get started. mqtt protocol 1 MQTT Protocol Features Publish and Subscribe QoS … Read more
xxhzz @PortalLab Lab 1. Introduction to MQTT Protocol MQTT is a “lightweight” communication protocol based on the publish/subscribe model, built on the TCP/IP protocol. It is lightweight, open, simple, and designed to be easy to implement, making these features particularly suitable for constrained environments such as machine-to-machine (M2M) and Internet of Things (IoT) environments. Publish/Subscribe … Read more
Author: Free and Open Lake AI What Is MQTT Used For? MQTT is a lightweight messaging protocol typically used for IoT devices that are designed to be energy-efficient and consume minimal bandwidth. The MQTT protocol runs over TCP/IP and is based on a lossless two-way publish-subscribe model, ensuring that MQTT messages are transmitted efficiently and … Read more
MQTT (Message Queuing Telemetry Transport) is a “lightweight” communication protocol based on the publish/subscribe model. This protocol is built on top of the TCP/IP protocol and was released by IBM in 1999. The biggest advantage of MQTT is that it can provide real-time and reliable messaging services for connecting remote devices with very little code … Read more
Purpose of Building Qt Root Filesystem The purpose of building the Buildroot Qt root filesystem is to create a customized filesystem for embedded systems that integrates the Qt libraries and applications. Buildroot is an open-source tool for building embedded Linux systems, providing a simple and flexible way to generate a complete root filesystem image. By … Read more
In actual project development, engineers may need to port some tools or protocols in the file system. So how should we perform the porting operation? We can add package configurations to port new features in the Buildroot of the OK113i-S development board. In this article, I will introduce how to port the MQTT protocol in … Read more
