The core of Industry 4.0 is the Industrial Internet of Things (IIoT), which enables factories to connect machines, sensors, robots, and other devices to the internet and to each other. When implementing IIoT, selecting the right communication standard that meets the needs of Industry 4.0 is a key challenge. MQTT Sparkplug is a communication protocol … Read more
MQTT is a widely used messaging protocol in IoT projects, utilizing a publish–subscribe model for message communication. Below, we will demonstrate how to implement publishing–subscribe message data to an MQTT server using Java. First, include the pom dependency: <dependency> <groupId>org.eclipse.paho</groupId> <artifactId>org.eclipse.paho.client.mqttv3</artifactId> <version>1.2.5</version></dependency> Publish a JSON message to vehicle/monitor/{userId} as shown in the demo below: public … Read more
