	498	+== 5.1 How does it work? ==
	499	+
	500	+
	501	+We use the Mosquitto MQTT client to simulate MQTT messages, acting as a virtual device. First, install the Mosquitto client on your computer from [[this link>>url:https://mosquitto.org/download/]]. The Mosquitto client publishes messages to the MQTT broker (HiveMQ) on a specified MQTT topic. ThingsBoard subscribes to these messages using the same topic.
	502	+
	503	+The Mosquitto client publishes messages on the topic v1/devices/[device_name]/telemetry. The [device_name]placeholder can be replaced with any device name, for example, 'S31B-NB'. Then, the MQTT topic would be v1/devices/S31B-NB/telemetry.
	504	+
	505	+On the ThingsBoard side, we configure the MQTT topic subscription as v1/devices/+/telemetry. The + wildcard represents any device name and allows ThingsBoard to automatically create (provision) a device with that name, such as S31B-NB, for example.
	506	+
	507	+
	508	+**The new device is created the first time the MQTT topic is received. For subsequent MQTT topics with the same device name, no duplicate devices will be created.**
	509	+
	510	+
	511	+For example, if you send two MQTT messages with different device names in the topic:
	512	+
	513	+1. v1/devices/**S31B-NB**/telemetry
	514	+1. v1/devices/**LDS25-NB**/telemetry
	515	+
	516	+ThingsBoard will create two devices named **S31B-NB** and **LDS25-NB** in the **//Devices//** section.
	517	+
	518	+
	519	+The MQTT payload format is as follows, which is common for all ~-~-NB and ~-~-CB series devices:

	541	+Also, a new device named **S31B-NB** will appear under **//Entities -> Devices -> All//**. This means the first MQTT message triggers ThingsBoard to provision a device named **S31B-NB**.

	545	+
	546	+

	548	+
	549	+Then go to the **Latest telemetry** tab.
	550	+
	551	+You can see the fields temperature and humidity with the values you previously sent using the MQTT message.
	552	+
	553	+
	554	+[[image:telemetry-1.png]]
	555	+
	556	+
	557	+Now, change the values of the fields and send the MQTT message again. For example, set temperature to 20 and humidity to 70. Observe how the values update in //Latest Telemetry//.

	576	+= 6. Creating a Dashboard =
	577	+
	578	+ThingsBoard **Dashboards** provide a powerful way to visualize and monitor real-time and historical data from connected devices. They allow users to create interactive, customizable panels displaying telemetry data, device status, and other key metrics. With a variety of widgets, including charts, maps, and tables, dashboards help users gain insights, track trends, and manage IoT deployments efficiently.
	579	+
	580	+
	581	+This section guides you on how to create a dashboard to display temperature and humidity data from the device on a time-series chart. You may also use other widgets in ThingsBoard to display data according to your requirements.
	582	+
	583	+
	584	+In **ThingsBoard**, from the left navigation menu, click **Dashboards**. Then, click the **+** button and select **Create new dashboard** from the dropdown menu.
	585	+
	586	+
	587	+[[image:dashboard-1.png]]
	588	+
	589	+
	590	+In the **Title** text box, enter **NB/CB Test Dashboard** as the title of the dashboard.
	591	+
	592	+Click on the **Add** button.

	614	+[[image:dashboard-5.png||height="525" width="700"]]
	615	+
	616	+
	617	+Configure the **Time series chart** widget as follows:
	618	+
	619	+* **Datasource** - select S31B-NB device you provisioned.
	620	+* **Series**:
	621	+** **temperature** - you can see this key by default.
	622	+** **humidity** - Click **Add series** button. Then add the **humidity** for the key and then type **%** as its unit.
	623	+* Click on the **Add** button.
	624	+
	625	+[[image:timeseries-1.png||height="491" width="700"]]
	626	+
	627	+
	628	+The time-series chart will appear in edit mode. Resize it by clicking and dragging the lower-right corner.
	629	+
	630	+Click the **Save** button to add the widget to the dashboard.
	631	+
	632	+
	633	+[[image:timeseries-3.png||height="347" width="700"]]
	634	+
	635	+

	654	+= 7. Configure NB-IoT Sensor =
	655	+
	656	+
	657	+Now, let's experiment with sending data to ThingsBoard using a real NB-IoT device. For example, we will use the **S31B-NB**.
	658	+
	659	+First, configure the NB-IoT device with the necessary MQTT settings using AT commands. Below is a list of AT commands you can use.
	660	+
	661	+
	662	+**AT Commands**
	663	+
	664	+* **AT+PRO=3,3    **~/~/ Use MQTT to connect to ThingsBoard. Payload Type set to 3.
	665	+* **AT+SUBTOPIC=<MQTT topic>**
	666	+* **AT+PUBTOPIC=<MQTT topic>**
	667	+* **AT+CLIENT=null**
	668	+* **AT+UNAME=<MQTT Username>**
	669	+* **AT+PWD=<MQTT Password>**
	670	+* **AT+SERVADDR=<Broker address, Port>**
	671	+
	672	+Test your uplink by pressing the ACT button for 1 second.
