Troubleshooting • Arduino data --> rasperryPi5 --> nodejs webserver

Code:

const { SerialPort } = require('serialport');const ReadlineParser = require('@serialport/parser-readline');const express = require('express');const http = require('http');const WebSocket = require('ws');const app = express();const port = 3000; // Port for your server;var Serialport  = new SerialPort('/dev/ttyAMA0',{baudRate:9600,dataBits:8,parity: 'none',flowControl: false});const parser = Serialport.pipe(new ReadlineParser({ delimiter: '\r\n' }));// Create an HTTP serverconst server = http.createServer(app);// Create a WebSocket server attached to the HTTP serverconst wss = new WebSocket.Server({ server });// Define the route to serve the HTML pageapp.get('/', (req, res) => {  res.sendFile(__dirname + '/index.html');});// Start listening to UART dataparser.on('open', function(data) {  console.log('Serial port is open');  parser.on('data', (data) => {    console.log('Received data from UART:', data);    // Broadcast the received data to all WebSocket clients    wss.clients.forEach((client) => {      if (client.readyState === WebSocket.OPEN) {        client.send(data);      }    });  });});// Start the HTTP serverserver.listen(port, () => {  console.log(`Server listening at http://localhost:${port}`);});
