MaQaiTTo.com has more than 1000 active users and at least 2000 device connections per day and still aims to provide a true free service. However it works on AWS cloud instance which has monthly payments. To create a smoother service for IoT community traffic, disk and bandwidth limits have increased which costs a lot after increasing user and device count. Now we kindly invite you to support MaQiaTTo and build better and totally free environment for instant IoT device connectivity. Use the button below to support us for a better MQTT experience.
MQTT stands for MQ Telemetry Transport. It is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks. The design principles are to minimise network bandwidth and device resource requirements whilst also attempting to ensure reliability and some degree of assurance of delivery. These principles also turn out to make the protocol ideal of the emerging “machine-to-machine” (M2M) or “Internet of Things” world of connected devices, and for mobile applications where bandwidth and battery power are at a premium.
Each node that connected to MQTT Broker have the ability of listening incoming messages to a specific topic which means subscribing; and sending some data to specific topic which means publishing.
