I'm trying to use node to print the Serial from Arduino uno connected to USB
I have a file script.js:
var SerialPort= require("serialport");
SerialPort.list(function(err,ports){
ports.forEach(function(port){
console.log(port.comName);
console.log(port.manufacturer);
});
});
var port= new SerialPort("/dev/cu.usbmodem641",{
baudRate: 9600,
parser: SerialPort.parsers.readline('n')
});
port.on('open',function(){
console.log('opened');
});
port.on('close',function(){
console.log('closed');
});
port.on('data',function(data){
console.log(data);
});
port.on('error',function(error){
console.log("Errore: "+error);
});
console.log(":-)");
I run sudo node script.js while Arduino has Serial.println(1);
on terminal I see:
opened
closed
If I open Arduino IDE's serial monitor it correctly works!
Why my serial port doesn't stay opened?
