I want to use at the same time processing, puredata and tuio reactivision, but I can only run one, when processing is running with TUIO reactivision i have an error in PD "TuioClient: could not bind to UDP port 3333"... there is solution to this?

@brunof56 Normally you can only bind once. I don't know of any way to share the udp socket in Pure Data (that doesn't mean that someone else will not give you a solution).
I think it is more likely that you should bind first in Pure Data, and that you can (maybe) program SO_REUSEPORT in Processing.

http://stackoverflow.com/questions/4364434/let-two-udp-servers-listen-on-the-same-port

or maybe Gilberto's solution here:

http://forum.pdpatchrepo.info/topic/9275/tcl-invalid-command-name-listening-while-executing-listening-to-tuio-udp-messages-on-port-3333/2

will work.

OR....... Much better, and much easier, you could receive the data on port 3333 ONLY in Pure Data, and then resend it to Processing on a different port... (or do the same thing in Processing).
