| /** |
| * IBM Watson IoT Platform Quickstart sample. |
| * Submits a JSON device event every second using the |
| * same format as the Quickstart device simulator, |
| * with keys {@code temp}, {@code humidity} and {@code objectTemp} |
| * and random values. |
| * <P> |
| * The device type is {@code iotsamples-edgent} and a random |
| * device identifier is generated. Both are printed out when |
| * the application starts. |
| * <P> |
| * A URL is also printed that allows viewing of the data |
| * as it received by the Quickstart service. |
| * <P> |
| * This sample demonstrates using the WIoTP API to initialize the IotpDevice |
| * connector as well as the ability to publish events using the WIoTP HTTP protocol. |
| * |
| * <p>See {@code scripts/connectors/iotp/README} for information about running the sample. |
