• store requests within a list using UUID as key
• match response with request using UUID
• store a function handler to be called when request if found in list

Todo

• create transaction handler
• link request with response from CSMS
• Allow function to be stored in transaction
  • call function when transaction is found and it's a response

Description

add ocpp frame handling and implement error handling

Requirements

• add ocpp frames
• add ocpp actions
• add ocpp function for sending and getting frames.

Todo

• add ocpp enums for actions and errors
• add ocpp frames
• add ocpp functions for creating ocpp error frame
• add ocpp functions for fetching ocpp error frames

Description

submit when ever a state changes at the charging station to the CSMS

Requirements

• update state when ever an event occur
• submit state to CSMS on change
• Allow user to change state using the UI

Todo

• add function to change the state

Description

A connection might be dropped at anytime during a session and it's critical for us to be able to identify and resume a connection as soon as possible.

Requirements

• prevent reconnection spam.
• ability to alter reconnection timeout during runtime.
• identify if a connection is dead or alive.

Todo
