Overview

A Charge Point sends notifications to inform the Central System about the progress of the firmware update. The Charge Point SHALL send a FirmwareStatusNotification.req PDU for informing the Central System about the progress of the downloading and installation of a firmware update. The Charge Point SHALL only send the status Idle after receipt of a TriggerMessage for a Firmware Status Notification, when it is not busy downloading/installing firmware.

Upon receipt of a FirmwareStatusNotification.req PDU, the Central System SHALL respond with a FirmwareStatusNotification.conf.
