How to use IoT in Bluemix Leonard Walletzký

Introducing IoT in BlueMIx http://discover-iot.eu-gb.mybluemix.net/

Smartphone as sensor Enter your Device ID and email Accept the conditions Click Next

How to use your device data in your app? Example – how to use simulated GPS device in the BlueMix First we need to create a new IoT application, simulating sensor In your dashboard, click to Create App Select IoT Platform Starter Name your app and click Create Wait for Node Red ready

Simulated sensor Select all nodes and delete In IS open the file IoTsensor.txt and select Import > Clipboard Copy the content of the file into the text frame Place the new flow Leave Node Red open and return to Dashboard

Connection to API Your application cannot communicate with sensor directly You need to create interface – to be able to communicate with more devices and prevent the attacks In the list of services find IoT Platform for your device

Watson IOT Board Remember your organization ID Click on Devices You need to create new device to be connected with your sensor Click Add Device Click on Create device type Click on Create device type again Enter name for the type – like Simulated_device and click Next Leave template and metadata blank by clicking Next and click Create

Create your device connection Select your type and click Next Add the name for the device Provide some simple token (12345678) Click Add After viewing the summary, you will see your device

Generating API connections Click on Apps Delete API Key Create new API Key Copy and save Authentication Token!!!! Click Generate

Connecting the device Go back to your Node Red editor DoubleClick on Publish to IoT node Click to Server To Server write: <your organization>.messaging.internetofthings.ibmcloud.com To Client ID: d:<your organization>:<device type>:<device name>

Connecting the device To Security part To username: use-token-auth To password copy your generated token for the device Press Update Press Done Press Deploy

Connecting the device Go to Watson IoT platform dashboard If you were successfull, you should see something like this

Creating the application Create New App From IS download phpmqtt library and put into your repository From IS download IoT_example.php Modify source code in IoT_example.php using your credentials Start your application

API to services How can I see all services connected to my app? How can I get their credentials? In Dashboard, click on App name and then to Connections Under each you can click to View Credentials

Variable VCAP_SERVICES All credentials are available via $ENV[„VCAP_SERVICES“] For of its usage see db.php in our previous MySQL example To see all credentials in command line use cf env <name of your app>

Get familiar with API Each service has detailed documentation of API
