Get started with Intel Edison (Node.js)
In this tutorial, you will learn the basics of using Intel Edison (that runs on the Linux-based Yocto). You will then learn how to seamlessly connect your devices to QNAP NAS using QIoT Suite Lite.
Please ensure your Intel Edison and NAS are under the same LAN.
1. Configure your device
Configure your Intel Edison with an operating system, set up your development environment, and deploy an application to Intel Edison.
1.1 Download Intel Edison drivers
Download dicers for Intel Edison based on your host PC, available here:
1.2 Configure and test your device
Getting started with Intel Edison
If this is your first time using Intel Edison, you must follow some steps to assemble it.
Follow steps 1-3 in the instructions.
- Step 1: Assemble boards and sensors.
- Step 2: Run setup tools.
Use the setup tool to flash the latest firmware on the Intel Edison development board via a convenient wizard. The setup tool also lets you enable SSH and Wi-Fi* connectivity to your board, as described in the steps to follow.
- Step 3: Download development environment.
Download the Intel® XDK cross-platform integrated development environment
Verify and upload your onBoardBlink project to Intel Edison
- Creating your project
- Launch the Intel XDK.
- Follow the on-screen instructions to log in to your Intel® XDK account or sign up for a new Intel XDK account.
- From the Projects tab, click Start a New Project in the bottom left. The Start a New Project page will opens.
- In the Internet of Things Embedded Application list on the left, click Templates. A list of templates will be displayed on the right.
- Select the Onboard LED Blink template, and click Continue.
- You can modify the directory to store your projects in Project Directory.
- Enter a name for the project in Project Name.
Connecting to the board
- If your development board is not included in the drop-down list, you must connect to your board manually. Select Add Manual Connectionand enter your board's IP address in Address.
- If you have created a user name and password to log in to your board, enter them in User Name and Password. Otherwise, leave the default values.
- Click "Connect".
- The daemon must be updated if it is out of date. This will disconnect from the board, as the daemon has to be restarted. Follow the instructions to reconnect when prompted.
- If the clock on your board and the Intel XDK IoT Edition is out of sync, click "Sync".
- A confirmation message will display the connection status and IP address of your development board. Click "Dismiss". Your board is now connected.
Upload and run the project
- Go to "Develop" tab and look for the IoT toolbar at the bottom of the window.
- Click the Upload icon to upload your project to the board.
- Click the Run icon to run your code. You should see a flashing LED on your board.
- Click the Stop icon to stop the LED.
Congratulations, you have run your first IoT app using the Intel XDK IoT Edition, please refer to https://software.intel.com/en-us/get-started-edison-windows
1.3 Install Node.js and required libraries
Open a terminal application on your computer and connect to Intel Edison.
Install the latest Node,js
2.1 Install QIoT Suite Lite
- QIoT Suite Lite can be installed from the App Center.
- Launch and log in to QIoT Suite Lite. The default username and password is "admin".
2.2 Create a new IoT application
IoT Applications are a combination of Things, Rules, and Dashboards. We recommend that you first create a “Things” in IoT Application. This IoT Application allows you to keep a record of all of the devices that are connected to your NAS.Rules make it possible to build IoT applications that gather, process, analyze and act on data generated by connected devices. Rules can apply to data from one or many devices, and it can take one or many actions in parallel.Dashboards, turn your data into analytics and reports that provide real-time insights.All these elements provide user a complete IoT Application environment.
- If this is your first time to use QIoT Suite Lite, use QIoT Quick Setup to guide you through a quick setup of an IoT application. After reading the introduction, click Next.
- Create a New IoT application
- Click "+ Add" to add this application’s device.
- Click "+Add", In "Add Things":
- Enter the IP address, User Name, and Password of your device and click the Connect icon. QIoT Suite Lite will check the connection with the device. After the connection is verified, click Next.
- In "Resources", click "Add Resource".
- In "Add Thing Resource":
- In "API Keys":
- Your IoT application will now be created. Node.js sample codes and related files (certificate, resource information) will be uploaded to the specified path on your device.
- A sample dashboard will be created
- Go to the Rule tab to define the flow or rules on how to process the data sent from the device, and how to present in a dashboard.
3. Connect your device to QIoT Suite Lite using MQTTS
3.1 Run Sample Code
- Open a Terminal application (such as PuTTY) on your PC.Connect to your device using SSH and enter the folder where the sample code is stored (for example: /home/root/bundle).
- To install sample code dependencies, enter the following commands:
- Run the sample code
- The device will send a message to the topic "temp" (or the topic you defined).
3.2 Using another protocol
- Click "Connect a Device".
- You can select another protocol.
- Connect to your device using SSH, and enter the following commands:
4. Integrate Power BI
4.1 Get your first Power BI account
- Sign up for a free PowerBI account at https://powerbi.microsoft.com/en-us/
- After a sequence of registration, the page will lead you to below page, you can press "My workspace", and "skip for now" button appear. You could click "skip for now "to start create dataset.
4.2 Setup your streaming dataset API
- Create "Datasets"
- Select "API", the source of your data, and click "Next".
- Define your values from stream (e.g., temp, max, min), and you will get a JSON result in the textbox. We will use this JSON code to push data to the QIoT Suite Lite application. Click "Create" to finish.
- Once you create your data stream, you get a REST API URL which IoT applications can call using POST requests to push your live data to the streaming data dataset you created.
4.3 Configure Node-RED’s nodes in IoT application
- Create IoT application in QIoT suite.
- The following is your first Node-RED flow, and then you can start creating your own IoT flow. You can learn more about Node-RED at https://nodered.org/
- Before you start pushing live data to Power BI. We need a "function" node to convert IoT data to a streaming data dataset. Here you can replace msg.payload to your JSON dataset.
- Function code as following:
- We need an "http request" node to help us to push live data to Power BI. Just drop and drag "http request" node and connect to tail of "function" node.
- Copy and paste the REST API URL that you got from the Power BI console, and set http method to POST. Click "Deploy" to save changes
- Your Node-RED flow will look like below.
4.4 Add tile to display real-time data
- Create "Dashboard"
- Click "Add tile" in screen upper right corner
- Select "CUSTOM STREAMING DATA" and then select the "Next" button.
- Select datasets and click "Next".
- Select visualization type (e.g., gauge), and set value, min, and max value.
- You have a streaming dataset to work with; you can get a real time gauge that looks like as following.
