How do I test my MQTT server?
- Start the broker: mosquitto.
- Start the command line subscriber: mosquitto_sub -v -t 'test/topic'
- Publish test message with the command line publisher: mosquitto_pub -t 'test/topic' -m 'helloWorld'
Keeping this in consideration, how do I know if MQTT is running?
If you are using Windows, open up a command prompt and type 'netstat -an'. If your server is running, you should be able to see the port 1883. If you cannot go to Task Manager > Services and start/restart the Mosquitto server from there.
Also to know is, how do I run a MQTT server?

- In the command prompt, navigate to the Mosquitto root folder, such as C:Program Files (x86)mosquitto.
- Start the Mosquitto service by running the command: "net start mosquitto".
