It will reboot, connect to the WiFi Network, and attempt to connect to The MQTT Broker with the information you have entered. Once you have settings entered as desired click the Save Settings button on The MQTT Gateway. More information is available in The MQTT Setup Guide. Take a look at Message Settings, this will allow you to customize the Topics the Gateway reports sensor data to as well as how the message data is formatted. Lastly Mosquitto by default listens For MQTT Client connections on port 1883 so be sure that is what is entered in the Port field(it should be by default). Also enter something for the Client ID field (something as simple as Gateway will work for now). For this enter the IP address of the computer running Mosquitto into the Server Settings IP field(leave the Domain field blank). Next you you’ll want to tell it what MQTT Broker it should connect to. For our testing purposes connect it to the same WiFi Network as the computer running Mosquitto. You’ll need to enter the network credentials for the WiFi Network you want it to connect to. That guide goes into great detail on the setup of the Gateway. I recommend opening the Setup Guide for The MQTT Gateway. When the gateway receives these wireless transmissions from the sensors it will parse the packet converting it into a JSON object and then it will publish that JSON object to an MQTT Topic relative to that particular sensor. The MQTT Gateway will receive wireless transmissions from our Enterprise Line of products. To do this we will connect an MQTT Gateway up to it. Now that the Mosquitto MQTT Broker is running on your computer we’re ready to start feeding some meaningful data into it. Congratulations you have Mosquitto running properly on your computer.

You’ll see in that Subscribe terminal you opened that you received a message. Now in a new terminal (Yes you should have 3 open now) enter: mosquitto_pub -t 'Important_Messages' -m 'This is an Important Service announcement, Mosquitto is working' Pretty sweet huh? Keep this terminal open also. This means we will now receive a payload whenever any other client publishes to the Important_Messages topic. However we are telling the Mosquitto broker that we are interested in messages that come through the Topic Important_Messages.

Since both the Broker and the Client are on the same computer we don’t have to tell Mosquitto much about what we want. This command will connect an MQTT Client on your computer to the Mosquitto broker also running on your computer. In the second terminal enter the following: mosquitto_sub -t 'Important_Messages' Leave this Terminal OpenĬonnect an MQTT Client to the Mosquitto Broker and listen for data That will simply start the Mosquitto Broker on your computer. If you have not already to ahead and start the Mosquitto Broker by entering the following in your terminal: mosquitto Once you dig into how configurable Mosquitto is you will see it really is a “heavy duty” tool.

We’ll leave it to the Official Documentation page for Mosquitto to explain more on that. You can however specify a configuration file to use which configures settings for the Broker such as authentication. This is the simplest way to launch the Mosquitto broker on your computer. Starting it up should be as simple as entering mosquitto in your terminal. Once installed you should have access to Mosquitto through your terminal.
