MeterValue not appeared in handler and can I send SetChargingProfile in starttransaction handler

[vcba79]

Hello,

I am trying to implement charger controller using Java-OCA-OCPP.

Server start ok and accept Authorize, StatusNotification, etc but not MeterValues. I have a python ocpp echo server shows charger send MeterValues after transaction started. But server provied by this project never call MeterValues handler. How can I identify this issue and solve it?

Is there a code example to show how to send SetChargingProfile in starttransaction handler? I have not idea how to send SetChargingProfile after transaction started.

Thanks,
