Name : mosquitto Product : Fedora 31 Version : 1.6.7 Release : 1.fc31 URL : http://mosquitto.org/ Summary : An Open Source MQTT v3.1/v3.1.1 Broker Description : Mosquitto is an open source message broker that implements the MQ Telemetry Transport protocol version 3.1 and 3.1.1 MQTT provides a lightweight method of carrying out messaging using a publish/subscribe model. This makes it suitable for "machine to machine" messaging such as with low power sensors or mobile devices such as phones, embedded computers or micro-controllers like the Arduino.
