To test the configuration, '''deploy''' the nodes again and send the message by clicking on the '''inject''' node.

===MQTT gateway using MQTT explorer and Node-RED broker===
----
In this example, we are going to use the same Node-RED broker configured in previous parts of this article, only this time we are going to use [http://mqtt-explorer.com/ MQTT Explorer] app to Publish and Subscribe to Modbus data.
Here's connection topology for this use case:

====Device setup====
----
Navigate to '''Services -> Modbus -> MQTT Gateway'''. Follow these steps for the configuration:
# '''Enable''': on
# '''Host''': input '''192.168.10.139''', or if you would like to use local broker on the device - input '''127.0.0.1'''
Leave everything else as default, or adjust according to your needs

====MQTT explorer setup and testing====
----
Open MQTT Explorer application and in the default screen input the '''Host IP (1)''' of MQTT Broker, then press '''Connect (2)'''.

Once done, locate Publish section on the right side. You can use the same settings as in previous sections of MQTT Gateway:
# '''Topic:''' request
# '''Data:''' 0 65432 0 192.168.10.1 502 5 1 3 6 2

If everything is set up correctly, then you should be able to see response from the router:
