13 +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.

397 -== 6.1 How does it work? ==
398 -
399 -
400 -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.
401 -
402 -The Mosquitto client publishes messages (payloads) on the topic **/device/a**. Of course, you can use any topic for testing.
403 -
404 -(% id="cke_bm_37386S" style="display:none" %) (%%)The MQTT payload format is as follows:
405 -
406 -{{code language="none"}}
407 -{"IMEI": "350693903995577", "temperature":25, "humidity":80, "pressure":1005}
408 -{{/code}}
409 -
410 -Once ThingsBoard receives this message, it forwards this payload to the matching device through the integration.
411 -
412 -
413 -== 5.2 Sending messages ==
414 -
415 -
416 -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.
417 -
418 -{{code language="none"}}
419 -mosquitto_pub -d -q 1 -h 011731f7928xxxxx.s1.eu.hivemq.cloud -p 8883 -u "xxxxx" -P "xxxxx" -t "device/a" -m '{"IMEI":"350693903995577", "temperature":30, "humidity":80, "pressure":1005}'
420 -{{/code}}
421 -
422 -If the integration was performed without errors, the status of the integration changes to 'Active' after the first telemetry transmission.

426 -
427 -
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 2025-03-26 at 19.49.31.png]]
459 -
460 -
461 -
462 -
463 -Then click on the **three dots (...)** in the **Message** column. You can see the uplink message's **payload** in the **Message** window.
464 -
465 -
466 -[[image:Screenshot 2025-03-26 at 19.47.52.png]]
467 -
468 -
469 -
470 -
471 -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.

474 -= 7. Creating a Dashboard =
475 -
476 -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.
477 -
478 -
479 -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.
480 -
481 -
482 -First simulate a few messages using MQTT. This time, we have added the 'humidity' field to the payload. Eg:
483 -
484 -{{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}}
485 485  
486 -
487 -In **ThingsBoard**, from the left navigation menu, click **Dashboards**. Then, click the **+** button and select **Create new dashboard** from the dropdown menu.

560 -Now, let's experiment with sending data to ThingsBoard using a real NB-IoT device. For example, we will use the **TS01-NB**.
561 -
562 -First, configure the NB-IoT device with the necessary MQTT settings using AT commands. Below is a list of AT commands you can use.
563 -
564 -

570 -* **AT+CLIENT=null**
571 -* **AT+UNAME=<MQTT Username>**
572 -* **AT+PWD=<MQTT Password>**
573 -* **AT+SERVADDR=<Broker address, Port>**

575 -Test your uplink by pressing the ACT button for 1 second.
576 -
577 -
578 -
579 -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**.
