This section shows how to run the battery simulation, the battery manager and the dummy energy app. The following steps need to be performed.
Open the demo.bndrun file in the cnf project.
Make sure that org. flexiblepower.simulation.battery, flexiblepower.battery.manager and flexiblepower.dummy.energyapp are part of the “Run Requirements”. Click the “Resolve” button to check whether additional resources are needed and then press “Finish”. Save the demo.bndrun file and click on the “Run OSGi” button. This will start OSGI.
Point your web browser at http://localhost:8080 to see the Dashboard of EF-Pi.
Open another tab and go to http://localhost:8080/system/console/configMgr. Should you need to authenticate yourself use “admin”, “admin”.
Press the “+” button next to “Battery simulation config”.
This opens the configuration for the battery simulation, which contains several configuration items to control the simulation of the battery. Simply keep all default values and press the “Save” button. As soon as the configuration is saved a new battery simulation component will be started. In the eclipse console logging rules from o.f.s.battery.BatterySimulation will start to appear. This component is now running.
Start the Battery manager (“Battery manager config” in the Apache Felix Web Console) and the Dummy Energy App in a similar manner.
The three components are now running separately from each other. They need to be connected to be able to exchange messages. This is done via the EF-Pi ConnectionManager.
In the Apache Felix Web Console click on “Main” → “EF-Pi: ConnectionManager”. This opens the ConnectionManager in the browser.
The ConnectionManager graphically displays the different components (that were started previously) as rectangles. Each component has one or more ports that are depicted as circles. The dotted line shows potential connections that can be made between the ports of the different components.
Click on the “Autoconnect” button to automatically connect all potential connections.
The connections will now show up green, which means that the connection has been realized and messages can be exchanged between the components. These messages are also logged in the eclipse console. The EF-Pi dashboard also shows that the battery simulation is charging. The instruction to charge was sent by the Dummy Energy App.
When encountering unexpected errors, first try the following solutions:
- We might have missed empty directories, make sure there is a test and a res directory in each package.
- Clean all projects under Project → Clean
- Clean and rebuild the current bndtools project under the Build tab of the corresponding bnd.bnd:
In case you get the error below while it does not give a reason, you can try to simply delete the error and see if it dares to return.
