Router setup when using the router as a broker consists of two parts. First, we are going to set up a local broker. In order to do so, navigate to '''Services -> MQTT -> Broker''' and enable the broker.

Here we are using Node-RED as MQTT Broker, so we are going to do necessary changes in order for this functionality to work.

Here is the connection topology for this use case:

===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:
 +
 +
[[File:Nodered configurationexample topo6.png|border|800px|class=tlt-border]]
 +
 +
====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
 +
 +
[[File:MQTT gateway settings node red local router.png|border|500px|class=tlt-border]]
 +
 +
====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)'''.
 +
 +
[[File:Mqtt explorer server connection to broker example.png|border|600px|class=tlt-border]]
 +
 +
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
 +
 +
[[File:Publish from mqtt explorer node red example.png|border|500px|class=tlt-border]]
 +
 +
If everything is set up correctly, then you should be able to see response from the router:

In this section, we are going to upload Modbus data to server on Node-RED. First of all, we are going to need Modbus data source, in this example we are using the same device as Modbus TCP Slave and Master.

In this section, we are going to upload Bluetooth data to server on Node-RED. The configuration is going to be similar to Modbus data to server. More information about bluetooth functionality ant usage with beacons could be found in [[Teltonika EYE device pairing and data sender configuration example]].

In this article, several use cases are discussed, such as MQTT gateway using Node-RED or Teltonika device as MQTT broker, Modbus data to server, Bluetooth data to server, HTTP data to Node-RED server, and MQTT gateway using MQTT Explorer. The article provides steps on how to install Node-RED on a Linux virtual machine, install MQTT-specific nodes, and set up a local server. The article also explains how to use the Teltonika device as an MQTT broker and set up Node-RED to work with it.
