==Introduction==
This Technical Note (TN) illustrates how to run [https://thingsboard.io/docs/iot-gateway/what-is-iot-gateway/ ''ThingsBoard IoT Gateway'' software] on the [[MISC-TN-004:_Running_Debian_(armbian)_on_SBCSPG#The_hardware_platform|SBCSBP gateway product]] running Debian Busterand get it working in tandem with [https://thingsboard.io/docs/ ''ThingsBoard IoT platform'']. As an example, the following configuration was set up:
==Installing ''ThingsBoard IoT Gateway''==
$ sudo pip3 install --upgrade protobuf
Requirement already satisfied: protobuf in /usr/local/lib/python3.7/dist-packages (3.10.0)
== Testing ==
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, associated to the variables ''temperature'' and ''humidity'', are published :
<pre class="board-terminal">
armbian@sbcspg:~$ mosquitto_pub -h 127.0.0.1 -p 1883 -u "testuser" -P "testuser" -t "/sensor/SN-001/data" -m '{"sensorType": "Thermometer", "sensorModel": "T1000", "temp": 22, "hum": 55}'
</pre>
By setting the logging level of the broker to <code>all</code>, a lot of useful messages are printed. For example, they come to help for understanding if the data are received properly by the ''ThingsBoard IoT Gateway''<nowiki/>'s MQTT connector:
<pre class="board-terminal">
armbian@sbcspg:~$ sudo tail -n 100 -f /var/log/mosquitto/mosquitto.log
...
1643982761: New connection from 127.0.0.1 on port 1883.
1643982761: New client connected from 127.0.0.1 as mosqpub|4975-sbcspg (c1, k60, u'testuser').
1643982761: No will message specified.
1643982761: Sending CONNACK to mosqpub|4975-sbcspg (0, 0)
1643982761: Received PUBLISH from mosqpub|4975-sbcspg (d0, q0, r0, m0, '/sensor/SN-001/data', ... (76 bytes))
1643982761: Sending PUBLISH to ThingsBoard_gateway (d0, q0, r0, m0, '/sensor/SN-001/data', ... (76 bytes))
1643982761: Received DISCONNECT from mosqpub|4975-sbcspg
1643982761: Client mosqpub|4975-sbcspg disconnected.
1643982811: Received PINGREQ from ThingsBoard_gateway
1643982811: Sending PINGRESP to ThingsBoard_gateway
</pre>
In turn, ''ThingsBoard IoT Gateway'' finally sends the data to the ''ThingsBoard IoT platform'':

=== Remote logging ===''ThingsBoard'' provides the ''Remote logging'' functionality too. It can be extremely helpful when it comes to debug connections issues, for instance. It can be enabled as described [https://thingsboard.io/docs/iot-gateway/configguides/mqtthow-to-enable-remote-logging/here].
