Testing with Steve

I am trying to use this project as a chargepoint simulator to make tests with a central system that is running with Steve, now that it supports OCPP 1.6 (https://github.com/RWTH-i5-IDSG/steve). But I haven’t succeded on receiving any message in the Steve central system, neither using SOAP nor JSON types.

I have created a very basic main app that simply starts a chargepoint:

FakeChargePoint chargePoint = new FakeChargePoint();
chargePoint.connect();
chargePoint.sendBootNotification("A", "B");
chargePoint.sendHeartbeatRequest();

And in the constructor of the FakeChargePoint class I have changed the url to the ones that are provided by steve once it is started:

switch (type) {
            case JSON:
                client = new JSONClient(core, "testdummy");
                url = "ws://192.168.1.7:9220/steve/websocket/CentralSystemService/testdummy";
                break;
            case SOAP:
                client = new SOAPClient("me", new URL("http://127.0.0.1:8889"), core);
                url = "http://192.168.1.7:9220/steve/services/CentralSystemService";
                break;
        }

This code compiles and executes without problems or error messages. However, the Steve central system does not seem to be receiving anything at all from the chargepoint.

What is missing?

Not that I have anything to add re the “bug” at the moment, but SteVe does indeed look like an interesting project since apparently it supports OCPP 1.6J.

It was searching for an open source 1.6J “server” that led me here in the first place.

Thank you very much @goekay I certainly did not get the point in your sentence about the websocket. Now everything makes sense and it is working like a charm. I am going to close this issue.

Regarding the exception with SOAP, I will investigate further before raising a new issue. Thanks again!
