Introduction: How to Connect DragonBoard 410C to IBM Watson IoT Platform
This article will guide you to connect the Dragonboard 410C to the IBM Watson IoT Platform.
By the end of this tutorial, the board will be able to send a string to the IBM Plataform.
To send sensor data, just build a string that includes this values.
Step 1: Installing MQTT-Client Embedded C at DragonBoard 410C
Choose a device type
In this tutorial I assume that the DragonBoard 410C has alip-Linaro OS , install MQTT-Client for Embedded C in DragonBoard 410C board.
Open a terminal in 410C and type:
git clone https://github.com/ibm-messaging/iotf-embeddedc.git
You ill need your github login and pass. iot-embeddedc folder will be creted.
Go inside this folder.
You will notice the following structure:
ls MakeLists.txt LICENSE README.md lib samples setup.sh src test
This command will download paho mqtt and unzip it.
It will also download cJSON and unzip it.
It will copy the correct files to lib folder.
Go inside samples folder and run make.
Step 2: Creating an Account in IBM Watson IoT Plataform
Access IBM Watson IoT Plataform at http://www.ibm.com/internet-of-things/iot-solution...
Step 3: Fill the Form
Step 4: Check Your Email
Click in confirmation and complete the registration.
Step 5: Welcome to Bleumix
Click in create.
Step 6: Create Space
Step 7: I'm Ready!
Step 8: Create App
Step 9: Select Internet of Things Platform Starter.
Step 10: Create App Name and Host. Don't Touch Other Options
Step 11: Create the App - and We Will Use the Plataform
Step 12: Click Overview for the Dashboard.
Step 13: All Bords Are Avaliable Aut the Dashboard
Step 14: Add Device
Step 15: Create Device Name and Definition
Step 16: Fill With a Description for the Device
Step 17: Select What Is Best for Your Product
I chose Manufacturer and Model.
Step 18: Define the Selected Options
Step 19: Choose a Device Type
Step 20: Choose a Device Type
Step 21: Just to Confirm the Informations
Step 22: Don't Add Anything to Metadata
Step 23: You Don't Need to Provide a Toke
Step 24: Add Device
Step 25: Verify the Informations
Step 26: How to Configure DragonBoard 410C to Connect in IBM Watson IoT Plataform
Edit file device.cfg.
Fill this file with the informations provided by the Watson IoT Plataform, relative to your account.
auth-token=p*dwNZZZzvUWoKKK4B ~ ~
Save this file
Execute file sampleDevice and the board will connect to Watson IoT and send string “temp = 34”. To send sensors data, for example, you just need to change this string format.
Connecting to registered service with org 6v7XXX
Publishing the event stat with rc 0
Step 27: The Dashboard Should Be Like This
Step 28: Status Displays the String Sent Using MQTT
Step 29: All Usage Can Be Monitored
