Blebricks NODEs

Blebricks, what are they?

Blebricks consist of a set of modular "smart bricks": the BLE-B, constitutes the fundamental brick, the heart of the system, and communicates directly via Bluetooth with the relevant mobile application or through remote servers with our Gateways or by means of specific communication Blebricks. The other bricks go into a set of sensors, actuators, power units, and communication modules that include Wi-Fi, Ethernet, and LP-WAN (Low-Power Wide-Area Network) technologies. The various Blebricks are then assembled together according to the requirements of the various applications, interlocking the functionality they need in a similar way to how LEGO is done. Once connected, the bricks recognize each other and are able to self-configure to function immediately. The prototype IoT (Internet of Things) device built in this way is ready to work.
The technology is ultra low-power and therefore suitable for creating portable and wearable devices or for battery-powered uses.
A set of mobile applications (MakeApp), coding tools (App Inventor), a powerful Bricksdoor platform based on Node-RED along with third-party web platforms make Proof-Of-Concept immediate. The development cost and time for the realization of new IoT products and solutions are drastically lowered, thanks also to an efficient "turnkey" industrialization service.

How to use Blebricks with Node-RED?

The thing is very simple, as each "Blebricks node" corresponds to a physical Blebrick equivalent. To use the nodes it will sufficient to:
1) create the hardware prototype by embedding the Blebricks.
2) Connect the Blebricks to an MQTT broker via Gateways, Blebrick ESP or Bricksdoor app.
3) Enter the node corresponding to the used Blebricks into the flowNode-RED and configure it with the IP of the MQTT broker and the topic used.
4) connect a graphics unit (e.g. gauge, graph etc) from the Node-Red Dashboard palette or other processing nodes as desired

You will be able to find more information at this link: https://www.bleb.it/quickstart/#Esempi_Bricksboard
More examples on how to use the single nodes can be directly imported from the Import menu of your Node-RED environment. Just select Import -> Examples and then open the directory "@blebtechnology/node-red-blebricks" to import a working example of your Blebrick Node.

What Nodes can I find in the Blebricks Palette?

As a general rule to get furhter details on individual Blebricks and nodes, once entered in yout node-red environment, you can hover your mouse over the node red "Blebricks" palette where the various NODE Blebricks are listed.
Depending on their physical functionalities Blebricks nodes are organized in the following self-explanatory main groups:
