  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.
--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.
++The Mosquitto client publishes messages (payloads) on the topic **v1/devices/me/telemetry**. Of course, you can use any topic for testing.
--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.
++(% id="cke_bm_37386S" style="display:none" %) (%%)The MQTT payload format is as follows, which is common for all **~-~-NB** and **~-~-CB** series devices. The **IMEI** field is mandatory and is used to provision a new device with the name assigned to it in ThingsBoard.
++{{code language="none"}}
++{"IMEI": "S31B-NB", "temperature": 27, ......}
++{{/code}}
--**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.**
++Once ThingsBoard receives this message, it automatically creates (provisions) the device mentioned in the **IMEI**, for example, S31B-NB.
--For example, if you send two MQTT messages with different device names in the topic:
++== 5.2 Sending messages ==
--1. v1/devices/**S31B-NB**/telemetry
--1. v1/devices/**S31B-CB**/telemetry
--ThingsBoard will create two devices named **S31B-NB** and **S31B-CB** in the **//Devices//** section.
++On the terminal, issue the following MQTT command which simulates the device S31B-NB. The message payload contains the fields temperature and humidity, which hold the values S31B-NB and 27, respectively. This payload is also (technically) known as telemetry.
--
--The MQTT payload format is as follows, for example:
--
  {{code language="none"}}
--{"temperature":10.4, "humidity":85}
++mosquitto_pub -d -q 1 -h 011731f7928xxxxx.s1.eu.hivemq.cloud -p 8883 -t "v1/devices/me/telemetry" -u "xxxxx" -P "xxxxx" -m '{"IMEI": "S31B-NB", "temperature": 27}'
  {{/code}}
++If the integration was performed without errors, the status of the integration changes to 'Active' after the first telemetry transmission.
--== 5.2 Sending messages ==
++[[image:integration-active.png]]
--On the terminal, issue the following MQTT command which simulates the device S31B-NB. The message payload contains the fields temperature and humidity, which hold the values 10.4 and 85, respectively. This payload is also (technically) known as telemetry.
++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**.
++
++
++[[image:new-device.png]]
++
++
++== 6.3 Viewing messages ==
++
++
++Go back to the **Integrations** page.
++
++Click on the **MQTT integration NB/CB** in the **Integrations** page to see its details.
++
++Click on the **Edit** button (//**pen icon**//).
++
++Click on the **Disabled** button in the upper-right corner.
++
++Turn on the **All messages (15 min)** option. This will enable displaying all messages in the **Events** tab. This setting will expire in 15 minutes, and you will need to repeat the same steps if you want to view the messages in the Events tab later.
++
++Click on the **Apply** button.
++
++Then click on the **Apply changes** (//**tick icon**//) button.
++
++
++[[image:Screenshot 2025-03-18 at 09.23.10.png]]
++
++
++Now go to the **Events** tab.
++
++Select the Event type as **Debug** from the dropdown list.
++
++Now you can see all the Uplink messages you are simulating through the MQTT broker. The status should be OK if there is no errors in your integration.
++
++
++[[image:Screenshot 2025-03-16 at 18.38.59.png]]
++
++
++Then click on the **three dots (...)** in the **Message** column. You can see the uplink message's **payload** in the **Message** window.
++
++
++[[image:Screenshot 2025-03-16 at 18.39.12.png]]
++
++
++Now, you have successfully tested your integration with a simulated uplink payload and verified that it is received by ThingsBoard, and the device is provisioned.
++
++
++= 7. Creating a Dashboard =
++
++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.
++
++
++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.
++
++
++First simulate a few messages using MQTT. This time, we have added the 'humidity' field to the payload. Eg:
++
++{{code language="none"}}mosquitto_pub -d -q 1 -h 011731f7928xxxxx.s1.eu.hivemq.cloud -p 8883 -t "v1/devices/me/telemetry" -u "xxxxx" -P "xxxxx" -m '{"IMEI": "S31B-NB", "temperature": 22, "humidity":80}'{{/code}}
++
++
++In **ThingsBoard**, from the left navigation menu, click **Dashboards**. Then, click the **+** button and select **Create new dashboard** from the dropdown menu.
++
++
++[[image:dashboard-1.png]]

++
++Click on the **Add** button.

++
++
++
++In the **Charts: select widget** window, click **Time series chart**.
++
++
++[[image:dashboard-5.png||height="525" width="700"]]
++
++
++Configure the **Time series chart** widget as follows:
++
++* **Datasource** - select S31B-NB device you provisioned.
++* **Series**:
++** **temperature** - you can see this key by default.
++** **humidity** - Click **Add series** button. Then add the **humidity** for the key and then type **%** as its unit.
++* Click on the **Add** button.
++
++[[image:timeseries-1.png||height="491" width="700"]]
++
++
++The time-series chart will appear in edit mode. Resize it by clicking and dragging the lower-right corner.
++
++Click the **Save** button to add the widget to the dashboard.
++
++
++[[image:timeseries-3.png||height="347" width="700"]]
++
++
++Now send the following MQTT messages from the terminal to simulate the data.

++= 8. Configure NB-IoT Sensor =
++
++
++Now, let's experiment with sending data to ThingsBoard using a real NB-IoT device. For example, we will use the **TS01-NB**.
++
++First, configure the NB-IoT device with the necessary MQTT settings using AT commands. Below is a list of AT commands you can use.
++
++
++**AT Commands**
++
++* **AT+PRO=3,3    **~/~/ Use MQTT to connect to ThingsBoard. Payload Type set to 3.
++* **AT+SUBTOPIC=<MQTT subscribe topic> Eg: TS01-NB**
++* **AT+PUBTOPIC=<MQTT publish topic> Eg: TS01-NB**
++* **AT+CLIENT=null**
++* **AT+UNAME=<MQTT Username>**
++* **AT+PWD=<MQTT Password>**
++* **AT+SERVADDR=<Broker address, Port>**
++
++Test your uplink by pressing the ACT button for 1 second.
++
++
++
++The following image shows the uplink payload of a real Dragino device. The publish topic is **TS01-NB**, and the device name is **861275077962896**, which is represented by the **IMEI**.
++
++{{info}}
++The ThingsBoard uses the device's IMEI number included in the payload to create a device in the Devices section.
