--------------------------------------------------------------------------------------------------------- ##Task 3: Basics of MQTT Protocol Date: 14-10-2022 Aim: Learn the basics of MQTT protocol and its working Read an article on MQTT and its working. MQTT stands for Message Queuing Telemetry Transport which is a messaging protocol for communication between IOT devices. MQTT - Publish / Subscribe: Devices publish messages on a topic and all the devices that are subscribed to that specific topic receive the message. MQTT - Messages: Information which is exchanged between devices which can be commands to control outputs , read and publish data from sensor nodes or data like sensor readings. MQTT - Topics: Topics are the way we register interest for incoming messages or specify where we want to publish the message. Basically , they are similar to addresses. MQTT - Broker: The MQTT Broker is responsible for receiving and filtering all the messages , deciding which devices are interested in them and publishing the message to all subscribed clients/devices. In home automation , we preferably use the Mosquitto Broker on Raspberry Pi. Finally , read about how to use MQTT in Home Automation and IOT projects. --------------------------------------------------------------------------------------------------------- Utkarsh R 3rd Year ECE UVCE "
