Installation and Use of Mqtt -- MQTT.fx

Installation and use of mqtt.fx
MQTT.fx is currently a mainstream mqtt client that can quickly verify whether it can communicate with the IoT Hub service to publish or subscribe to messages. The device sends the current status as an MQTT topic to the IoT Hub, with each MQTT topic having a different level of name, such as "Building/Floor/Temperature." The MQTT proxy server sends the received topic to all subscribed clients.
