Dilisi S 21.1 15 This document guides you on integrating Dragino **-NB** and **-CB** series devices data with ThingsBoard. For this guide, we use ThingsBoard Cloud, which is one of the ThingsBoard versions that allows you to try it for free.
Dilisi S 2.1 16
Dilisi S 21.1 17 The **NB series** devices end with the suffix **-NB**, and the **CB series** devices end with the suffix **-CB**. For example, **S31B-NB** is an **NB device**, and **S31-CB** is a **CB device**.

Dilisi S 117.1 22 To complete this tutorial, you need to have the following:
Xiaoling 64.2 23
Dilisi S 121.1 24 * ThingsBoard cloud account
Dilisi S 155.1 25 * MQTT Broker (public or private) such as,
26 ** **[[HiveMQ Cloud>>https://www.hivemq.com]] - You can create a free account to try it or subscribe for a paid account. - We use HiveMQ Cloud as the MQTT broker to build example in this tutorial.**
27 ** [[emqx>>https://www.emqx.com/zh/mqtt/public-mqtt5-broker]] - The public MQTT server is only used for MOTT learning and testing, and should not be used in the production environment.
28 ** [[lns1.thingseye.io>>http://lns1.thingseye.io/]] - This is Dragino's MQTT broker, which requires a CA certificate to use.

Dilisi S 121.1 168
169
Dilisi S 176.1 170 First, you need to create devices in ThingsBoard to represent your physical devices. For example, you can name it **Device A**, and the second device could be **Device B** or any name you prefer. The device name should be unique within the **Devices** space.
171
172
173 In the left navigation, click Entities -> Devices.
174
175 Click the **Add Device** button (the button with the **+** sign), and from the dropdown menu, click **Add new device**.
176
177 In the **Add new device** dialog box, enter the device name in the **Name** text box. For example, we will use **Device A**.
178
179 Click the **Add** button.
180
181 Skip the **connectivity testing** by clicking the **Close** button.
182
183 The device is created and listed on the **Devices** page. Note that its initial state is **Inactive** because it has not received any data yet.

187
188
Dilisi S 93.1 189 In **ThingsBoard**, **Data Converters** are components used to transform incoming or outgoing data between different formats, typically to convert raw telemetry data from devices into a structured format that ThingsBoard can understand, or vice versa.

Dilisi S 176.1 393 == 6.1 How does it work? ==
Dilisi S 64.1 394
Dilisi S 141.1 395
Dilisi S 130.1 396 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.
397
Dilisi S 159.1 398 The Mosquitto client publishes messages (payloads) on the topic **v1/devices/me/telemetry**. Of course, you can use any topic for testing.
Dilisi S 130.1 399
Dilisi S 159.1 400 (% 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.
Dilisi S 130.1 401
Dilisi S 64.1 402 {{code language="none"}}
Dilisi S 159.1 403 {"IMEI": "S31B-NB", "temperature": 27, ......}
Dilisi S 64.1 404 {{/code}}
405
Dilisi S 159.1 406 Once ThingsBoard receives this message, it automatically creates (provisions) the device mentioned in the **IMEI**, for example, S31B-NB.
Dilisi S 130.1 407
Dilisi S 159.1 408
Dilisi S 130.1 409 == 5.2 Sending messages ==
410
411
Dilisi S 161.1 412 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.
Dilisi S 130.1 413
414 {{code language="none"}}
Dilisi S 161.1 415 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}'
Dilisi S 130.1 416 {{/code}}
417
Dilisi S 141.1 418 If the integration was performed without errors, the status of the integration changes to 'Active' after the first telemetry transmission.
419
420
421 [[image:integration-active.png]]
422
423
424 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**.

Dilisi S 145.1 472 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.

Dilisi S 145.1 475 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.
Dilisi S 141.1 476
Dilisi S 145.1 477
Dilisi S 169.1 478 First simulate a few messages using MQTT. This time, we have added the 'humidity' field to the payload. Eg:

Dilisi S 169.1 481
482
Dilisi S 145.1 483 In **ThingsBoard**, from the left navigation menu, click **Dashboards**. Then, click the **+** button and select **Create new dashboard** from the dropdown menu.

Dilisi S 149.1 518 * **Datasource** - select S31B-NB device you provisioned.
519 * **Series**:
Dilisi S 145.1 520 ** **temperature** - you can see this key by default.
Dilisi S 149.1 521 ** **humidity** - Click **Add series** button. Then add the **humidity** for the key and then type **%** as its unit.
Dilisi S 145.1 522 * Click on the **Add** button.

Dilisi S 172.1 556 Now, let's experiment with sending data to ThingsBoard using a real NB-IoT device. For example, we will use the **TS01-NB**.
Dilisi S 146.1 557
558 First, configure the NB-IoT device with the necessary MQTT settings using AT commands. Below is a list of AT commands you can use.
559
560
561 **AT Commands**
562
Dilisi S 149.1 563 * **AT+PRO=3,3    **~/~/ Use MQTT to connect to ThingsBoard. Payload Type set to 3.
Dilisi S 175.1 564 * **AT+SUBTOPIC=<MQTT subscribe topic> Eg: TS01-NB**
Dilisi S 169.1 565 * **AT+PUBTOPIC=<MQTT publish topic> Eg: TS01-NB**
Dilisi S 150.1 566 * **AT+CLIENT=null**
567 * **AT+UNAME=<MQTT Username>**
568 * **AT+PWD=<MQTT Password>**
Dilisi S 152.1 569 * **AT+SERVADDR=<Broker address, Port>**
Dilisi S 146.1 570
Dilisi S 150.1 571 Test your uplink by pressing the ACT button for 1 second.
