What is the MQTT protocol, and how is it used to integrate Eclipse Kura and Kapua?
The MQTT protocol, or Message Queuing Telemetry Transport, is a lightweight and efficient messaging protocol designed for low-bandwidth, high-latency, or unreliable networks. It serves as a means to facilitate communication between devices in the Internet of Things (IoT) ecosystem. MQTT operates on a publish-subscribe model, where devices can publish messages to specific “topics,” and other devices subscribe to these topics to receive relevant messages. In the context of Eclipse Kura and Kapua, MQTT is commonly used for seamless integration. Kura can act as an MQTT client, allowing devices to publish data to Kapua, which serves as an MQTT broker. This setup enables efficient data transfer, real-time communication, and remote device management, making MQTT a fundamental protocol for IoT applications using Kura and Kapua.
