What does MQTT stand for?
In respect to this, what is MQTT used for?
MQTT stands for Message Queuing Telemetry Transport. It is a lightweight publish and subscribe system where you can publish and receive messages as a client. MQTT is a simple messaging protocol, designed for constrained devices with low-bandwidth. So, it's the perfect solution for Internet of Things applications.
Also Know, does MQTT require Internet? Yes, to send or receive messages, the MQTT client must establish a TCP connection to the broker. However, MQTT comes with features specifically designed to cope with unstable network connections, like the broker buffering incoming messages for disconnected clients.
Also know, what is MQTT protocol and how it works?
MQTT is a publish/subscribe protocol that allows edge-of-network devices to publish to a broker. Clients connect to this broker, which then mediates communication between the two devices. When another client publishes a message on a subscribed topic, the broker forwards the message to any client that has subscribed.
What is MQTT broker?
Depending on the implementation, a broker can handle up to thousands of concurrently connected MQTT clients. The broker is responsible for receiving all messages, filtering the messages, determining who is subscribed to each message, and sending the message to these subscribed clients.
