Moving from OCPP v1.6 to v2.0

[ezolti]

Hi
I am building a charging center.
When using v1.6 I used a class that implements ServerCoreEventHandler which handles all Requests (8 of them).
like handleBootNotificationRequest , handleMeterValuesRequest.
Now in v2.0, I can see Feature that need to be used but only 2 handlers
IServerBootNotificationRequestHandler and IServerStatusNotificationRequestHandler
What am I missing?
What do I need to do?
Thanks

Hi @ezolti,

Thank you for using this new discussion section to ask you question.

As far as I can tell you should implement the ServerProvisioningEventHandler:

https://github.com/ChargeTimeEU/Java-OCA-OCPP/blob/master/ocpp-v2/src/main/java/eu/chargetime/ocpp/v201/feature/function/ServerProvisioningEventHandler.java

Please note there is two version 2 modules at this moment, the one I started way back with a new architecture (where handlers were part of the feature, to simplify iterative implementations) and the new v2 which supports multiple protocol versions. You should use v2.

I am using

com.github.ChargeTimeEU.Java-OCA-OCPP
common
v1.2


com.github.ChargeTimeEU.Java-OCA-OCPP
OCPP-J
v1.2


com.github.ChargeTimeEU.Java-OCA-OCPP
v2_0
v1.2

The error is : The import eu.chargetime.ocpp.v201 cannot be resolved
which dependency to use ?

[ezolti]

I use mvn install and use it on my local repository

eu.chargetime.ocpp
v1_6
1.2.0


eu.chargetime.ocpp
common
1.2.0


eu.chargetime.ocpp
ocpp-v2
1.2.0

@TVolden
In ServerProvisioningEventHandler there are 3
handleBootNotificationRequest
handleHeartbeatRequest
handleNotifyReportRequest
What should I do with the rest which are in use at OCPP v1.6?
handleMeterValuesRequest
handleStartTransactionRequest
handleStopTransactionRequest
and others.
Thanks

@TVolden
Can you please point to the right way to go?

Hi @ezolti,

I'm not sure, I haven't implemented this part. The specification kinda dropped the idea of feature profiles, so it a little more messy now.

Take a look in: https://github.com/ChargeTimeEU/Java-OCA-OCPP/tree/master/ocpp-v2/src/main/java/eu/chargetime/ocpp/v201/feature/function

There is a ServerTransactionEventHandler interface, I think that may be it.
