6 years ago You get this error because there is no server listening for the client to connect to. There is no public OCPP server that accepts connections that I know of, so the README uses an example that does not work unless you set up a server yourself.
If you want to get the client to connect without writing any code, you can use the example server. Run this in one terminal to start the server:
sbt "project example-json-server" run and this in another terminal to start the client connecting to it:
sbt "project example-json-client" "run 01234567 ws://localhost:2345/ 1.5"The client and server will then exchange a few messages. The server should print something like:
Example server listening at port 2345. Press ENTER to exit.
