Subject: fix(ocpp20): send TransactionEvent(Started) on RequestStartTransaction (E02.FR.01)
X-Git-Tag: ocpp-server@v3.1.1~18
X-Git-Url: https://git.piment-noir.org/?a=commitdiff_plain;h=52054291e5525a2ac7ba738e268a9a067f74b3ac;p=e-mobility-charging-stations-simulator.git

fix(ocpp20): send TransactionEvent(Started) on RequestStartTransaction (E02.FR.01)

The handler accepted remote start transactions without notifying the
CSMS via TransactionEvent. Per E02.FR.01, the CS SHALL send
TransactionEvent with eventType=Started when a transaction begins.

Also starts meter values interval for the new transaction.
