11 This configure instruction is for Dragino NB-IoT models with -NB or -NS suffix, for example DDS75-NB. These models use the same NB-IoT Module **[[BC660K-GL>>https://www.quectel.com/product/lpwa-bc660k-gl-nb2]]** and has the same software structure. The have the same configure instruction to different IoT servers. Use can follow the instruction here to see how to configure to connect to those servers.

311 == 3.4 Datacake ==
312
313 == 3.4.1 Define Product ==
314
315
316 Firstly, we need to set the MQTT mode to datacake, and we need to run** AT+PRO=3,2**. This command is set to datacake. After running the command, the device automatically sets the server address, port.
317
318
319 By chosing to add the device under a **"New Product"** you are required to give a name for this product. You can name it something like "My First MQTT Product".
320
321 [[image:image-20230802112413-14.png]]
322
323 == 1.2 Create Device ==
324
325 In the second step you have to define the device which should be added to the product.
326
327 [[image:image-20230802112413-15.png]]
328
329 Enter a name here (such as "My First MQTT Device") and complete the creation of the device by clicking on the "Next" button.
330
331
332 == 1.3 Create Database Fields ==
333
334 After creating the device, it is listed in the table of the fleet view. Now open the device by clicking on the entry in the list.
335
336 You will then see a device view with an empty dashboard. Now, the first thing we want to do is navigate to the Device configuration. To do this, use the tab bar and click on "Configuration".

339
340 [[image:image-20230802112413-17.png]]
341
342 To create a first database field, please click on the "Add Field" button as marked in the screenshot above.
343
344 This will open another modal asking for some required input for your first field.

349
350 == 1.4 Set up Broker ==
351
352 The broker is running on mqtt.datacake.co on ports 1883 and 8883. Port 1883 is unsecured and should not be used in production environments. Port 8883 uses a CA signed server certificate.
353
354 You will need an access token to log into the Datacake MQTT Broker. You can use your own personal token or create a token explicitly for individual devices or groups of devices.
355
356 View your Personal Access Token
357
358 You can view your own token via the User-Settings-Menu. You can reach this menu by clicking on "Edit Profile" at the end of the list using the Workspace Selector:

361
362 MQTT Client-ID
363
364 The Datacake Broker manages the client IDs internally. You do not need to worry about a client ID. If your client optionally supports the specification of a client ID, please leave this specification blank. Your client then creates a randomly generated ID.
365
366 AT+CLIENT=“Any value”

375 == 1.6 Create your first Subscription ==
376
377 Subscribe
378
379 Data is published according to the following structure:
380
381 dtck~/~//
382
383 Subscribe to topics using this structure to receive messages via MQTT when readings (via API or MQTT) arrive in the Datacake Cloud. Messages are published whenever there is a change to a corresponding database field.

402
403 Publish
404
405 To upload data into the Datacake Cloud and into a specific device, you publish the data to the respective topic structure.
406
407 Due to the nature of MQTT, the topic prefix differs as follows:
408
409 dtck-pub~/~//

411 example:

458
459 Uplink Converter
460
461 The purpose of the decoder function is to parse the incoming data and metadata to a format that ThingsBoard can consume. deviceName and deviceType are required, while attributes and telemetry are optional. Attributes and telemetry are flat key-value objects. Nested objects are not supported.
462
463 To create an uplink converter go to the Integrations center -> Data converters page and click “plus” button. Name it “MQTT Uplink Converter” and select type Uplink. Use debug mode for now.

474 Note:Our device payload is already human readable data. Therefore, users do not need to write decoders. Simply create by default.
