What is MQTT mainly used for?

MQTT is used for data exchange between constrained devices and server applications. It keeps bandwidth requirements to an absolute minimum, handles unreliable networks, requires little implementation effort for developers, and is, therefore, ideal for machine-to-machine (M2M) communication.

What is MQTT protocol and its use with its API use case?

It allows you to send messages on a topic (channels) passed through a centralized message broker. The MQTT module of API will take care of the publish/ subscribe mechanism along with additional features like authentication, retaining messages and sending duplicate messages to unreachable clients.

In a nutshell, MQTT uses your existing Internet home network to send messages to your IoT devices and respond to those messages. MQTT (Message Queuing Telemetry Transport) is a publish/subscribe messaging protocol that works on top of the TCP/IP protocol.

What are the major protocols used in IoT?

Overview of IoT protocols

  • Message Queuing Telemetry Transport (MQTT)
  • ZigBee.
  • Bluetooth.
  • Extensible Messaging and Presence Protocol (XMPP)
  • Data-Distribution Service (DDS)
  • Advanced Message Queuing Protocol (AMQP)
  • Lightweight M2M (LwM2M)

What are most commonly used IoT protocols?

Most common protocols

  1. AMQP. Short for Advanced Message Queuing Protocol, AMQP is an open standard protocol used for more message-oriented middleware.
  2. Bluetooth and BLE. Bluetooth is a short-range wireless technology that uses short wavelength ultra-high frequency radio waves.
  3. Cellular.
  4. CoAP.
  5. DDS.
  6. LoRa and LoRaWAN.
  7. LWM2M.
  8. MQTT.

Which of the following protocols is used by Usart?

RS232C
1. What is the protocol used by USART? Explanation: RS232C is a long established standard (“c” is the current version) that describes the physical interface and protocol for relatively low speed serial data communication between computers and relates devices.

What are the benefits of the MQTT protocol in terms of security?

Among MQTT’s advantages over competing protocols are the following:

  • efficient data transmission and quick to implement, due to its being a lightweight protocol;
  • low network usage, due to minimized data packets;
  • efficient distribution of data;
  • successful implementation of remote sensing and control;
