MQTT is a lightweight, open messaging protocol that provides resource-constrained network clients with an easy way to distribute telemetry information in low-bandwidth environments. serial port ethernet converter The protocol uses a publish/subscribe communication model for machine-to-machine ( M2M ) communication.
Created as a low-overhead protocol to accommodate bandwidth and CPU constraints, MQTT was designed to run in embedded environments where it can provide a reliable, efficient communication path. MQTT is suitable for connecting devices with a small code footprint, and it’s a good choice for wireless networks that experience varying levels of latency due to occasional bandwidth constraints or unreliable connections. The agreement applies to industries ranging from automotive to energy to telecommunications.
Although MQTT started as a proprietary protocol for communicating with Supervisory Control and Data Acquisition (SCADA) systems in the oil and gas industry, it has become popular in the world of smart devices and is today the leading open source protocol for connecting the Internet of Things (IoT ) and Industrial IoT ( IIoT ) devices.
While the TT in MQTT stands for modbus tcp gateway Telemetry Transport, MQ refers to a product called IBM MQ. Although the spelling of MQTT is sometimes referred to as Message Queue Telemetry Transport, there is no message queue in MQTT communication.
