''ThingsBoard IoT Gateway'' is interfaced to a local MQTT broker (''[https://mosquitto.org/ Mosquitto]'') via the [https://thingsboard.io/docs/iot-gateway/config/mqtt/ MQTT connector]. On the network side, ''ThingsBoard IoT Gateway'' is connected to an instance of ''[https://thingsboard.io/docs/ ThingsBoard IoT platform Community Edition]''. For the sake of simplicity, this instance was installed on a PC. The PC and the SBCSPG gateway are connected to the same LAN. Obviously, in a more realistic scenario, the ThingsBoard IoT platform would be installed on a remote server or on a cloud infrastructure. See [https://thingsboard.io/docs/user-guide/install/installation-options/ this page] for more information about installation options.

To test the configuration, it is possible to publish some data with the help of the <code>mosquitto_pub</code> client tool. In the following example, two data points are published , associated to the variables ''temperature'' and ''humidity'', are published :

In turn, ''ThingsBoard IoT Gateway'' finally manages to send sends the data to the ''ThingsBoard IoT platform'':
