Not receiving OSC from Bela to MaxMSP

OLav

I'm facing a challenge with my Bela platform where I'm unable to receive OSC messages sent from MaxMSP. Here's a rundown of the situation:

I have the Bela connected to my laptop (Mac 13.2.1) via usb and ethernet cable. My max patch is also running on the same laptop.
I have a Max patch sending OSC float values to the Bela IP address 192.168.7.1, formatted with /osc
When I run the bela script, all I get in the terminal output is bela: From 127.0.0.1:35613. I have seen other discussion posts detailing the print output was From 192.168.7.1:35613. Why would mine be defaulting to 127.0.0.1?
I am also not receiving the "test" message I send from bela to Max.
I am also connected to my home wifi - not sure if this would be affecting the OSC.
I have also tried settting const char* remoteIp = "0.0.0.0"; which doesn't resolve the issue.

#include <Bela.h>
#include <cmath>
#include <libraries/OscSender/OscSender.h>
#include <libraries/OscReceiver/OscReceiver.h>

OscReceiver oscReceiver;
OscSender oscSender;
int localPort = 7562;
int remotePort = 7563;
const char* remoteIp = "192.168.7.1";


void on_receive(oscpkt::Message* msg, const char* addr, void* arg)
{
	printf("From %s\n", addr);
	
	if(msg->match("/osc")) {
		float floatArg;
		msg->match("/osc").popFloat(floatArg).isOkNoMoreArgs();
		printf("received a message with float %f\n", floatArg);
	}
}

bool setup(BelaContext *context, void *userData)
{
	oscReceiver.setup(localPort, on_receive);
	oscSender.setup(remotePort, remoteIp);
	
	oscSender.newMessage("test").send();

	return true;
}

void render(BelaContext *context, void *userData)
{
}

void cleanup(BelaContext *context, void *userData)
{

}

I'm puzzled about what might be going wrong and why Bela isn't receiving the messages from MaxMSP. Do I need to be doing something different in my max patch? If anyone has insights or troubleshooting suggestions, it would be greatly appreciated.

Thanks in advance for your help!

OLav I have a Max patch sending OSC float values to the Bela IP address 192.168.7.1, formatted with /osc

On that USB network connection, your host computer is 192.168.7.1, while Bela is 192.168.7.2 . Therefore, from Max you should be sending to 192.168.7.2 .

OLav I have also tried settting const char* remoteIp = "0.0.0.0"; which doesn't resolve the issue.

AFAIK, 0.0.0.0 can only be used when listening for incoming messages onto a port and it means "receive any message sent to this port from any source IP". So, it wouldn't be good to send to.

OLav When I run the bela script, all I get in the terminal output is bela: From 127.0.0.1:35613

Is there anything in the body of the received OSC message? Who's sending it? Try printing msg->addressPattern().

You don't show the receiving part of the max patch or enough code on the Bela side to be able to tell you what's going on in that direction.

OLav via usb and ethernet cable

is the ethernet relevant here? Things should work over USB even if you have an ethernet cable "sidechain" ... I don't think it would cause disruptions.

giuliomoro Ah yes, switching the port to 192.168.7.2 did the trick! Really appreciate your quick feedback.

Thanks a bunch.
