hawkBit Device Simulator

The device simulator handles software update commands from the update server.

Run on your own workstation

java -jar examples/hawkbit-device-simulator/target/hawkbit-device-simulator-*-SNAPSHOT.jar

Or:

run org.eclipse.hawkbit.simulator.DeviceSimulator

Deploy to cloud foundry environment

• Go to target subfolder.
• Run cf push

Notes

The simulator has user authentication enabled in cloud profile. Default credentials:

• username : admin
• passwd : admin

This can be configured/disabled by spring boot properties

Usage

Graphical User Interface

The device simulator comes with a graphical user interface which makes it very easy to generate dummy devices handled by the device simulator. The status and the update progress of the simulated device are shown in the UI. The UI can be accessed via the URL:

http://localhost:8083

REST API

The device simulator exposes an REST-API which can be used to trigger device creation.

Optional parameters:

• name : name prefix simulated devices (default: "dmfSimulated"), followed by counter
• amount : number of simulated devices (default: 20, capped at: 4000)
• tenant : in a multi-tenenat ready hawkBit installation (default: "DEFAULT")
• api : the API which should be used for the simulated device either dmf or ddi (default: "ddi")
• endpoint : URL which defines the hawkbit DDI base endpoint (deffault: "http://localhost:8080")
• polldelay : number in milliseconds of the delay when DDI simulated devices should poll the endpoint (default: "30")
• gatewaytoken : an hawkbit gateway token to be used in case hawkbit does not allow anonymous access for DDI devices (default: "")

Example: for 20 simulated devices (default)

http://localhost:8083/start

Example: for 10 simulated devices that start with the name prefix "activeSim":

http://localhost:8083/start?amount=10&name=activeSim

Example: for 5 simulated devices that start with the name prefix "ddi" using the Direct Device Integration API (http):

http://localhost:8083/start?amount=5&name=ddi?api=ddi
