multiple apps listening on the same UDP port

[marcobrianza]

Hello, thank you for this great library.

I have the case where 2 processing applications running on the same computer need to receive messages on the same UDP port.

In my test with current version only the first application launched receives the messages.

In other cases using an artnet library in processing I was able to receive UDP messages on the same port. It might relate to an option to "reuse" the socket address. I think that the artnet library does it in this point:
https://github.com/cansik/artnet4j/blob/c923f4bd01e89d8912515d38407f6a875944f04a/src/main/java/ch/bildspur/artnet/ArtNetServer.java#L170

Is there a similar option in ocsP5?

Thank you
Marco

I have the same issue and would love to know if there's a simple solution.

@marcobrianza Of course this could be implemented. The base for oscp5 and artnet4j are the java sockets.

But to be honest, there are more issues than just this one, here a list of things that I would love to see:

• bind to a specific network interface
• broadcast support for datagram socket is not enabled
• oscEvent method swallows error messages
• bundles are not supported
• performance issues for sending out packages (always recreating a datagram socket)
• verbose logging clutters the terminal

And the fact that this library has not been updated since years is also not great. Maybe it makes sense to rewrite it based on a already existing and well supported OSC implementation like hoijui/JavaOSC.

Hi @cansik thanks for joining this thread, My Java level is really low, so I cannot handle to make a processing library.
I'm using your artnet library in a software that receives osc messages from touchosc and controls lights with artnet.
If you come up with an updated OSC processing library please let me know. see you. Marco

Hi, @marcobrianza I have already offered merge with my update of oscP5 library but it is probably abounded by maintainer. However, thanks to your comment I was able to create a non-blocking version from last Sojamo source code. You can find modified library that can coexist on the same port in my fork: https://github.com/trackme518/oscp5/releases . I have also added function to print the incoming IP with m.getIP() call.

hi @trackme518 thank you for the enhancement! I'll test it in the next project

hi @trackme518 thank you for the enhancement! I'll test it in the next project

How did it went? Can you star the repo so it's easier for others to find? https://github.com/trackme518/oscp5 thanks

Hi I think I have not used yet OSC in processing since a long time because I'm using MQTT lately. I have starred the project. Ciao!
