consumption

This directory has the sources for a Java application that uses the HCP IoT Services to interact with an IoT Device. It renders the received data that is stored in the database (that the MMS part of the IoT Services writes to) in an xy plot and lets you send data to the device via the API that the MMS part exposes for this purpose.

In order to compile and deploy our example application please get the sources to your system and go to the com.sap.iot.starterkit.ui directory.

Compilation and deployment

• Build the project with Maven using mvn clean install - it will produce the .war file to be used in the target directory
• Deploy the .war file using the HCP Cockpit > Java Application > Deploy Application but don't start it yet

• Select the application and go to Destinations > Import from file (use the provided file iotmms in the com.sap.iot.starterkit.ui/destinations folder) to correctly route requests from your User Interface to the iotmms application providing the MMS Services

• Within this process adapt URL, User and Password fields with the information for your account

• Select the application and go to Destinations > Import from file (use the provided file iotrdms in the com.sap.iot.starterkit.ui/destinations folder) to correctly route requests from your User Interface to the iotrdms application providing the RDMS Services

• Create a new Data Source Binding to ensure that both the iotmms as well as your UI application use the same database schema

Finally start your UI application by clicking at the URL for the running application and use it.
