使用Node.js或PHP从PHP桌面应用程序发送和读取串行数据

Question

as written in the title i made a stand alone web app using PHP Desktop, and now i want it to send and read data from a serial port.

I tried first to use this PHP Serial class (https://github.com/rubberneck/php-serial), but i had some problems, particulary on reading data, so i moved to javascript and node.js.

I installed Node.js and, using npm, serialport and ws packages, and I made the serialport work only with the node command on Windows cmd. I tried to follow some examples and extend the code to my PHP Desktop App using also the ws package but nothing seems to work and now I don't know how to go on.

Do you guys have any kind of suggestion? (Particullary on how to go on with the ws package)

What's the best solution to do this?

Thanks in advance.

Here's the codes that i used:

PHP code:

<?php

session_start();
include_once 'PhpSerial.php';

if(isset($_POST['serial'])) {


    $serial = new phpSerial;

    $serial->deviceSet("COM3");

    $serial->deviceOpen('w+') ;

    $serial->confBaudRate(115200);

    $serial->sendMessage($_POST['serial'],1);

    $_SESSION['serial_data'] = $serial->readPort();

    $serial->deviceClose(); 

}

else
    header('Location: index.php');

?>

JS code: (without the ws part, that didn't want to work)

var serialport = require('serialport');

var portName = "COM3";

var myPort = new serialport(portName, {
    baudRate: 115200
});

myPort.on('open', showPortOpen);
myPort.on('data', readSerialData);
myPort.on('close', showPortClose);
myPort.on('error', showError);

function showPortOpen() {
   console.log('port open. Data rate: ' + myPort.baudRate);
}

function readSerialData(data) {
   console.log(data);
}

function showPortClose() {
   console.log('port closed.');
}

function showError(error) {
   console.log('Serial port error: ' + error);
}
