IoT Cloud Platform gives you the tools to scale connections, gather and make sense of data, and provide the reliable customer experiences that hardware devices require. IBM Bluemix has a service that is part of its catalog to connect to the IBM IoT Cloud. In addition to the service, Bluemix has a boilerplate for the internet of things which stands up a Node-RED instance allowing you to design flows for your IoT data.
So, I made my own IT cloud service with IBM bluemix and ARM mbed platform; WIZnet WIZwiki-W7500 board. In the process, I’ve porting IBM cloud MQTT ethernet example for mbed to my WIZwiki-W7500 board.
I’ve posted at Instructables.
Step 1: Parts
WIZnet WIZwiki-W7500 Platform board
- WIZnet WIZwiki-W7500 is a WIZwiki platform board based on W7500. The IOP4IoT W7500 chip is one-chip solution which integrates an ARM Cortex-M0, 128KB Flash and hardwired TCP/IP core for various embedded application platform especially internet of things.

Step 2: Hardware Settings
Connect the WIZwiki-W7500 board and sensors using Grove baseboard.
- WIZwiki-W7500 board
- Grove Light sensor
- Grove Temperature sensor
Step 3: Create an application to process device data
- Go to IBM Bluemix and sign up
- Select the Internet of Things Foundation Starter Boilerplate by completing the following steps from your Bluemix dashboard
- Under “Applications”, click “Create an APP”
- Select that you would like to create a “Web” app
- Click “Browse Boilerplates” and click “Browse Boilerplates” once more
- Next to “Boilerplates”, select “Internet of Things Foundation”
- Finish adding the app by completing the following steps:
- Provide a name for your application
- Click the CREATE button
- After a short wait your application will start
- Once your application starts click the application URL to open the Node-RED Internet of Things landing page (this shows up as Routes: on your dashboard)
- Scroll down the Node-RED Internet of Things landing page and select the Go to your Node-RED flow editor button
For more details, please refer to the IBM recipes: ARM mbed IoT Starter Kit
Step 4: Device Registration and Link your App
- Double click the IBM IoT App In node in your Node-RED flow editor.
- In the Authentication type field, select Quickstart from the pull-down list.
- Enter the device ID of your board into the Device ID field.
- Look for the deploy button in the upper right hand corner of your Node-RED flow editor
Step 5: Import mbed program and modify the code for your auth info
- Go to ARM mbed developer site
- Import IBMIoTClientEthernetExample_WIZnet to your mbed web compiler.
- full fill your device auth codes (defines in main.cpp file)
- Compile and generate Binary
Step 6: Run and Enjoy it!
