node.js to read usb port signals

Question

I have installed serialport module for node.js using npm.(npm install serialport). Now I would like to send some messages from my android phone

Answer 1

Why, yes, it's certainly doable. There's a plenty of examples listed at the serialport package homepage itself.

Your node.js application will start with...

var SerialPort = require("serialport").SerialPort
var serialPort = new SerialPort("/dev/tty-usbserial1");

serialPort.on('data', function(data) { /* processing data */ });
