UDP <-> TCP

[xhpohanka]

Can I somehow route between TCP and UDP OSC? Like if I have an application which listens (and sends on UDP) and want to control it with an OSC TCP client...

Hi @xhpohanka,

Yes, this should be possible 👍

Here is an example where I configure OSCRouter to create a TCP server listening for incoming connections on port 9000:

Then I define a route, such that incoming OSC packets on port 9000 are sent to some other IP address and port via UDP. Note the input/output in the log window below:

Will try, thanks and merry Christmas 😉

I have tried, but unfortunately it doesn't work in my setup. I have an UDP osc application on the same device as the router (127.0.0.1). I see in the log UDP packets incoming, but for TCP I see only info that a client has connected, but no other packets...

Hey @xhpohanka,

I'd be happy to try and figure this out with you. Can you save your OSCRouter file and email it to me: chrismizerak at gmail dot com? We can troubleshoot over email, and then I can post the solution here, in case others will find it helpful.
