sending OSC on the same computer without wifi connection

karl_hungus

Hi, i send OSC messages both ways using P5 and SuperCollider on the same computer. Just noticed when wifi is off OSC communication stops. Why i need wifi for this and how to keep communication without it?

sojamo

are you using the loopback address 127.0.0.1?

karl_hungus

yes! what to do?

Hi, the following works for me, please read the comments

// tested on osx 10.9 (wifi turned off), Processing 2.2.1, oscP5 2.0.2
import oscP5.*;
import netP5.*;

OscP5 osc;
NetAddress receiver;

void setup() {
  size( 400 , 400 ); 
  osc = new OscP5( this,12000 );
  receiver = new NetAddress( "127.0.0.1" , 57120 ); // supercollider default port
}

void draw() {
  if(frameCount%10==0) {
    // send an OSC message to supercollder
    osc.send( receiver , "/freq" , random( 100,400 ));
  }
}

void oscEvent(OscMessage m) {
  // prints '127.0.0.1:57120 | pong i' into the console (sent from sc)
  println(m, millis());
}

/*

// Supercollider code (SuperCollider version 3.6)
// select 'Boot Server' from the menu-bar (under Language) to make sure server is running
// boot the server
s.boot;

// set remote address 
n = NetAddr("127.0.0.1", 12000);

// create a SynthDef which we will control via OSC
SynthDef(\ping, {|freq= 800| Out.ar(0, Line.kr(0.5, 0, 1.2, doneAction:2)*SinOsc.ar(freq))}).send(s);

// create an OSC listener for address pattern /freq listens at default port 57120
OSCFunc({|msg|
  Synth(\ping, [\freq, msg[1]]);"ping".postln;n.sendMsg("\pong",1);
}, '/freq');
