No BootNotification in examples

[iwo-strzebonski]

As the title says - there's no BootNotification example for the server nor the client, and the BootNotification is most important message, as it starts whole communication between the server and the charger.

Have you figured it out by any chance?

@cisc0disco I think I did?

I'll check in the evening

@cisc0disco sorry for my late response haha

This is my BootNotification handler:

import { BootNotificationRequest } from '@voltbras/ts-ocpp/dist/messages/json/request'
import { BootNotificationResponse } from '@voltbras/ts-ocpp/dist/messages/json/response'

export default async function bootNotificationHandler (
  chargePointId: string,
  data: BootNotificationRequest
): Promise<BootNotificationResponse> => {
  const response: BootNotificationResponse = {
    status: 'Accepted',
    currentTime: new Date().toISOString(),
    interval: 30
  }

  try {
    const charger = await Charger.init(chargePointId, data)

    if (charger instanceof Error) {
      response.status = 'Rejected'
      return response
    }
  } catch (err) {
    console.error('Error on bootNotificationHandler', err)
    response.status = 'Rejected'
    return response
  }

  return response
}

The Charger.init() method is used to initialize a charger in the database - it can be safely removed.

And this is my IncomingMessage handler:

import { OCPPRequestError, RequestMetadata } from '@voltbras/ts-ocpp'
import { ChargePointAction, ChargePointRequest } from '@voltbras/ts-ocpp/dist/messages/cp'
import { CentralSystemAction } from '@voltbras/ts-ocpp/dist/messages/cs'
import { OCPPVersionV16 } from '@voltbras/ts-ocpp/dist/types'

export default async function handleResponseActions (
  req: ChargePointRequest<OCPPVersionV16, ChargePointAction>,
  metadata: RequestMetadata
): Promise<{ [key: string]: unknown } | OCPPRequestError | Error> => {
  const { action, ocppVersion } = req
  const { chargePointId } = metadata
  let response

  const charger = await Charger.find(chargePointId)

  if (charger === null && action !== 'BootNotification') {
    setTimeout(() => forceBootNotification(ocppVersion, chargePointId), 1000)

    return new OCPPRequestError(`Charger ${chargePointId} not initialized. Please try again in a few seconds.`)
  }

  await Charger.changeState(chargePointId, 'Available')

  switch (req.action) {
    case 'BootNotification':
      response = await cp.bootNotificationHandler(chargePointId, req)
      break

    // other actions go here...

    default:
      return new OCPPRequestError(`Unknown action: ${req.action}`)
  }

  if (response instanceof Error) {
    console.error(`Error on action ${action}`, response)
    return response
  }

  return {
    action,
    ocppVersion,
    ...response
  }
}
