Working with the Retrieve Device Identification Information Node

In this quick tutorial, we will cover Working with the Retrieve Device Identification Information Node. In this tutorial, we’ll create a flow containing the Retrieve Device Identification Information Node.

In this video we will cover:

• Adding the node’s configuration information based on your needs
• Passing information as an input
• Deploying and testing your flow

Prerequisite

• A Free Catenis Development account or Production account
• Node-RED installed on either a local or cloud environment
• Catenis Flow Pallet installed on Node-RED
• A Catenis Virtual Device configured on Node-RED
• Basic understanding of how to use Node-RED
• Basic understanding of Retrieve Device Identification Information Node

After watching Working with the Retrieve Device Identification Node, feel free to watch the next video, Understanding the Export Asset Node, to further expand your knowledge.

Hi, this is Claire for Blockchain of Things.

In this tutorial, we’ll create a flow containing the Retrieve Device Identification Info Node.

If you don’t know what a Retrieve Device Identification Info Node is,

make sure you check out the previous tutorial

titled “Understanding The Retrieve Device Identification Info Node”.

Let’s begin!

Drag a Retrieve Device Identification Info Node into your workspace.

Double-click it to display its properties slide-out panel.

On the device drop-down field, choose your Catenis Virtual Device.

Add the node’s configuration information based on your needs to each field.

Wire this node, to a Debug Node, and open the Debug Sidebar.

Next, drag-and-drop an Inject Node into the Node-RED workspace.

Wire the Inject Node to the Retrieve Device Identification Info Node

then double-click the Inject Node to open its properties slide-out panel.

Alter the information in the Inject Nodes property slide-out panel by selecting the

drop-down payload field, and choose the JSON type.

An ellipse button will appear to the right of the field.

Click this ellipse button to display a JSON edit box.

Enter the JSON information you wish to pass as input to the Catenis Node.

For example, something like this,

but using your own device ID.

Click the done button.

Now, click deploy.

Now, let’s test the flow!

Click the button on the left of the Inject Node to send

the input from the Inject Node through the flow.

Great!

After watching this tutorial, you should know how to work

with the Retrieve Device Identification Info Node.

Great work!
