Just tinkering around.
Recently I'm trying to make a simple example where two processing apps talk to each other over OSC
(One running in android phone and the other in my computer)..
Now I first tried two apps both running in my computer (Both on local network 127.0.0.1 and swapped their ports)
Here are the codes:
Message sender (which send a random number every-time you mouse click in the applet window)
import oscP5.*;
import netP5.*;
OscP5 oscP5;
NetAddress myRemoteLocation;
float val;
void setup() {
size(200, 200);
/* start oscP5, listening for incoming messages at port 12000 */
oscP5 = new OscP5(this, 12000);
/* myRemoteLocation is a NetAddress. a NetAddress takes 2 parameters,
* an ip address and a port number. myRemoteLocation is used as parameter in
* oscP5.send() when sending osc packets to another computer, device,
* application. usage see below. for testing purposes the listening port
* and the port of the remote location address are the same, hence you will
* send messages back to this sketch.
*/
myRemoteLocation = new NetAddress("127.0.0.1", 8000);
}
void draw() {
background(255);
}
void mousePressed() {
//constitute message:
OscMessage myMessage = new OscMessage("/print");
myMessage.add(random(10, 100));
oscP5.send(myMessage, myRemoteLocation);
}
On the other hand the receiver processing app is kind of like this:
import oscP5.*;
import netP5.*;
OscP5 oscP5;
NetAddress myRemoteLocation;
float val;
void setup() {
size(200, 200);
/* start oscP5, listening for incoming messages at port 8000 */
oscP5 = new OscP5(this, 8000);
myRemoteLocation = new NetAddress("127.0.0.1", 12000);
}
void draw() {
background(0);
}
void oscEvent(OscMessage theOscMessage) {
val = theOscMessage.get(0).floatValue();
println("Val: " + val);
}
Now they seem to work on the computer ..
I imagined when porting it for android, I should just hardcode the ip-addresses .. But it doesn't work ..
Tried to look at some help from the ketai library , but there's no direct example for a simple communication.. One example(wifi_direct_remote_cursor) explains but it's very scattered. I couldn't understand why I need to check if I was on the same network and get client addresses and all ..
Can someone help me establish a simple example like above below ,
The message sender is the Android app and the message receiver is the computer app ..
Thanks in advance ..
