13 | |||
14 | |||
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. | ||
16 | |||
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**. | ||

22 | To complete this tutorial, you need to have the following: | ||
23 | |||
24 | * ThingsBoard cloud account | ||
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. | ||

159 | |||
160 | [[lns1.thingseye.io>>http://lns1.thingseye.io/]] is the Dragino's MQTT broker, which requires a CA certificate file, Certificate file, and the Private key file to use. | ||
161 | |||
162 | If customers need to use this MQTT connection with ThingsBoard, they need to contact the TE team to obtain three license files. | ||

165 | |||
166 | |||
167 | = 3. Creating Devices = | ||
168 | |||
169 | |||
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. | ||
184 | |||
185 | |||
186 | = 4. Data Converters = | ||
187 | |||
188 | |||
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. | ||
190 | |||
191 | |||
192 | == 4.1 Uplink == | ||

200 | |||
201 | On the **Data converters** page, click on the ‘**+**’ button, and then click on the **Create new converter** from the dropdown menu. | ||
202 | |||
203 | |||
204 | |||
205 | [[image:create-new-converter-menu.png||height="259" width="500"]] | ||
206 | |||
207 | |||
208 | The **Add data converter** window will appear. Name it ‘**MQTT Uplink Converter NB/CB**’ and select the Type as **Uplink**. | ||
209 | |||
210 | Click on the **TBEL** button if it has not been selected by default. | ||

264 | |||
265 | We use the same decoder function for all our devices. However, you need to modify a few things for each device. Among these, **deviceName** is a **mandatory** field. You should assign a device name to the **deviceName** field that matches the name of your device in the **Devices** section. | ||
266 | |||
267 | For example, if your device name is **Device B**, you can change **Device A** to **Device B**. | ||
268 | |||
269 | |||
270 | {{code language="JavaScript"}} | ||
271 | var deviceName = 'Device A'; | ||

307 | |||
308 | |||
309 | **Basic settings:** | ||
310 | |||
311 | * **Integration type**: MQTT | ||

331 | |||
332 | |||
333 | **Downlink data converter:** | ||
334 | |||
335 | Dragino NB/CB devices don't require a downlink data converter to decode their payloads, so you can skip this step. | ||
336 | |||
337 | * Click on the **Skip **button in the Downlink data converter section. | ||

381 | |||
382 | You should see that the newly added integration is listed on the **Integrations** page. | ||
383 | |||
384 | Since we haven't received data from a device yet, the integration **Status** is shown as **Pending.** | ||

387 | [[image:new-integration-pending.png]] | ||
388 | |||
389 | |||
390 | = 6. Verifying the receipt of data from virtual devices = | ||
391 | |||
392 | |||
393 | == 6.1 How does it work? == | ||
394 | |||
395 | |||
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 | |||
398 | The Mosquitto client publishes messages (payloads) on the topic **v1/devices/me/telemetry**. Of course, you can use any topic for testing. | ||
399 | |||
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. | ||
401 | |||
402 | {{code language="none"}} | ||
403 | {"IMEI": "S31B-NB", "temperature": 27, ......} | ||
404 | {{/code}} | ||
405 | |||
406 | Once ThingsBoard receives this message, it automatically creates (provisions) the device mentioned in the **IMEI**, for example, S31B-NB. | ||
407 | |||
408 | |||
409 | == 5.2 Sending messages == | ||
410 | |||
411 | |||
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. | ||
413 | |||
414 | {{code language="none"}} | ||
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}' | ||
416 | {{/code}} | ||
417 | |||
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**. | ||
425 | |||
426 | |||
427 | [[image:new-device.png]] | ||
428 | |||
429 | |||
430 | == 6.3 Viewing messages == | ||
431 | |||
432 | |||
433 | Go back to the **Integrations** page. | ||
434 | |||
435 | Click on the **MQTT integration NB/CB** in the **Integrations** page to see its details. | ||
436 | |||
437 | Click on the **Edit** button (//**pen icon**//). | ||
438 | |||
439 | Click on the **Disabled** button in the upper-right corner. | ||
440 | |||
441 | 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. | ||
442 | |||
443 | Click on the **Apply** button. | ||
444 | |||
445 | Then click on the **Apply changes** (//**tick icon**//) button. | ||
446 | |||
447 | |||
448 | [[image:Screenshot 2025-03-18 at 09.23.10.png]] | ||
449 | |||
450 | |||
451 | Now go to the **Events** tab. | ||
452 | |||
453 | Select the Event type as **Debug** from the dropdown list. | ||
454 | |||
455 | 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. | ||
456 | |||
457 | |||
458 | [[image:Screenshot 2025-03-16 at 18.38.59.png]] | ||
459 | |||
460 | |||
461 | Then click on the **three dots (...)** in the **Message** column. You can see the uplink message's **payload** in the **Message** window. | ||
462 | |||
463 | |||
464 | [[image:Screenshot 2025-03-16 at 18.39.12.png]] | ||
465 | |||
466 | |||
467 | 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. | ||
468 | |||
469 | |||
470 | = 7. Creating a Dashboard = | ||
471 | |||
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. | ||
473 | |||
474 | |||
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. | ||
476 | |||
477 | |||
478 | First simulate a few messages using MQTT. This time, we have added the 'humidity' field to the payload. Eg: | ||
479 | |||
480 | {{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}} | ||
481 | |||
482 | |||
483 | In **ThingsBoard**, from the left navigation menu, click **Dashboards**. Then, click the **+** button and select **Create new dashboard** from the dropdown menu. | ||
484 | |||
485 | |||
486 | [[image:dashboard-1.png]] | ||
487 | |||
488 | |||
489 | In the **Title** text box, enter **NB/CB Test Dashboard** as the title of the dashboard. | ||
490 | |||
491 | Click on the **Add** button. | ||
492 | |||

500 | [[image:dashboard-3.png]] | ||
501 | |||
502 | |||
503 | In the **Select widgets bundle** window, click **Charts**. | ||

506 | [[image:dashboard-4.png||height="537" width="700"]] | ||
507 | |||
508 | |||
509 | |||
510 | In the **Charts: select widget** window, click **Time series chart**. | ||
511 | |||
512 | |||
513 | [[image:dashboard-5.png||height="525" width="700"]] | ||
514 | |||
515 | |||
516 | Configure the **Time series chart** widget as follows: | ||
517 | |||
518 | * **Datasource** - select S31B-NB device you provisioned. | ||
519 | * **Series**: | ||
520 | ** **temperature** - you can see this key by default. | ||
521 | ** **humidity** - Click **Add series** button. Then add the **humidity** for the key and then type **%** as its unit. | ||
522 | * Click on the **Add** button. | ||
523 | |||
524 | [[image:timeseries-1.png||height="491" width="700"]] | ||
525 | |||
526 | |||
527 | The time-series chart will appear in edit mode. Resize it by clicking and dragging the lower-right corner. | ||
528 | |||
529 | Click the **Save** button to add the widget to the dashboard. | ||
530 | |||
531 | |||
532 | [[image:timeseries-3.png||height="347" width="700"]] | ||
533 | |||
534 | |||
535 | Now send the following MQTT messages from the terminal to simulate the data. | ||
536 | |||
537 | |||
538 | {{code language="none"}} | ||
539 | 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":70}' | ||
540 | |||
541 | 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, "humidity":72}' | ||
542 | |||
543 | 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": 19, "humidity":80}' | ||
544 | |||
545 | {{/code}} | ||
546 | |||
547 | The chart will update with the values in realtime, as shown in the below image. | ||
548 | |||
549 | |||
550 | [[image:timeseries-4.png||height="316" width="700"]] | ||
551 | |||
552 | |||
553 | = 8. Configure NB-IoT Sensor = | ||
554 | |||
555 | |||
556 | Now, let's experiment with sending data to ThingsBoard using a real NB-IoT device. For example, we will use the **TS01-NB**. | ||
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 | |||
563 | * **AT+PRO=3,3 **~/~/ Use MQTT to connect to ThingsBoard. Payload Type set to 3. | ||
564 | * **AT+SUBTOPIC=<MQTT subscribe topic> Eg: TS01-NB** | ||
565 | * **AT+PUBTOPIC=<MQTT publish topic> Eg: TS01-NB** | ||
566 | * **AT+CLIENT=null** | ||
567 | * **AT+UNAME=<MQTT Username>** | ||
568 | * **AT+PWD=<MQTT Password>** | ||
569 | * **AT+SERVADDR=<Broker address, Port>** | ||
570 | |||
571 | Test your uplink by pressing the ACT button for 1 second. | ||
572 | |||
573 | |||
574 | |||
575 | 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**. | ||
576 | |||
577 | {{info}} | ||
578 | The ThingsBoard uses the device's IMEI number included in the payload to create a device in the Devices section. | ||
579 | {{/info}} | ||
