Simulation With MQTTX

MQTTX Web provides 2 communication protocols, namely WebSocket (WS) and WebSocket Secure (WSS). There is also MQTTX Desktop, which is a more complete option.

1. If you are using MQTTX Web, make sure to select the WSS protocol to be secure.
   
   

2. If you are using MQTTX Desktop, don't forget to download the app. Then, once downloaded, open that application on your laptop or computer.
   
   

3. Click + New Connection -> then name the connection as you want -> then click Connect.
   
   

4. Create a new topic with the name kelasiot/pot.
   
   

5. Then for topic settings you can customize as seen below:

   • Format Payload to Publish by :   Plaintext.

   • Qos :   0.

   • Put a check mark on Retain.
   
   

6. Publish data.
   
   

7. After that, please click + New Subscription -> then list the topics you want to subscribe, for example: kelasiot/#.
   
   

8. Wait for the subscription results to be displayed.
   
   

9. Have fun and enjoy [Done].
