This was working:
system ( "node myprogram.js param1='Hello World' );
It stopped to work, presumably after I upgraded firmware.
I have also tried these:
system ( "node /home/root/myprogram.js param1='Hello World' );
system ( "/usr/bin/node myprogram.js param1='Hello World' );
What does you're your script does? Can you share your code? I would like to test it myself.
Also, which image are you using? And which version of the Arduino IDE are you using?
I think I found the problem.
My node script does a number of things, but the simple basic operation here was not working:
var request = require('request');
var fs = require('fs');
When I removed lines 1 and 2 it would work.
So it is not a problem of calling node.js.
I tried installing request module globally (npm install request -g) but it doesnt fix it.
Then I tried installing request module in the root folder (cd / ) + (npm install request)
That made it work.
system ("node /home/root/myscript.js");
I am using the 159.devkit version.
