QUESTION
Some Watson IoT samples use a d in device payloads {"d":{"temp":20}}
. As here in embedded c: :
ANSWER
Answered 2017-Apr-04 at 12:32All data is carried under a top level "d" element and an optional "ts" element exists, containing a timestamp for the message. If no ts element is present, the timestamp defaults to the time the message is received.
According to Bryan from the IoT team here:
IoT Foundation doesn't explicitly require a "d" top-level property in the JSON payload, however it does encourage this format to allow IoT Foundation to make some assumptions about how data is organized in the payload. If the IoT Foundation payload format is not followed, we refer to this as a "custom payload" in our documentation. IoT Foundation will allow you to publish a custom payload...

Install iot-java
You can use iot-java like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the iot-java component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
