Heartbeat request to virtual charge station

Question

I'm developing central system sofware for managing EV charging stations in Node.js. I am using ocpp-js library. After creating virtual charging point, i make request as

chargingPoint.heartbeat();

and after this request, virtual charge point send to draft central system. message in xml format within logs is written below.

and full code is written below:

app.js

var OCPP =  require('ocpp-js');
var express = require('express');
var app = express();


var options = {
  centralSystem: {
    port: 9220
  },
  chargingPoint: {
    serverURI: 'http://localhost:9221/Ocpp/ChargePointService',
    name: 'Simulator 1'
  },
  chargingPointServer: {
    port: 9221
  }
}

var ocppJS = new OCPP(options);

// Create Central System
var centralSystem = ocppJS.createCentralSystem();

// Create Charging Point Client
var chargingPoint1 = ocppJS.createChargingPoint('http://127.0.0.1:8081/ChargeBox/Ocpp', "chargingPoint1-Simulator");
//var chargingPoint2 = ocppJS.createChargingPoint('http://localhost:9221/Ocpp/ChargePointService', "chargingPoint2-Simulator");

// Charging Point Params can be also taken from options
//var chargingPoint1 = ocppJS.createChargingPoint();

// Create Charging Point Server
//var chargingPointServer = ocppJS.createChargingPointServer(9221);

//centralSystem.createChargeBoxClient(chargingPoint1);
centralSystem.clients.push(chargingPoint1);
 console.log(centralSystem);
 

 app.get('/', (req, res, next) => {
    chargingPoint1.heartbeat();
 });

 app.get('/bootNot', (req, res, next) => {
    res.json(chargingPoint1.bootNotification({req: "BootNotification"}));
 });

 app.get('/meterVal', (req, res, next) => {
    chargingPoint1.meterValues({meterValueRequest: "REQ"});
 });

 app.get('/getId', (req, res, next) => {
  res.json(chargingPoint1.getId());
 });
 
 app.listen(5000, (req, res, next) => {
    console.log("App is listening");
 });

I have a few quesions:

My first question is about completion of mission: according to logs has the heartbeat request completed successfully or not?

My last question is that if i create a SOAP server and sending request to soap clients (EV Charging units) with OCPP1.5 compliant data (maybe i'll use my own lib instead of occp-js), my created server can be accepted as an OCPP server?
