Hi,

I did not try liblo yet, but it would be the alternative, if I cannot figure out how to get it working with pyOSC.

Two general remarks - first: show us (some) code?
Do you _really_ expect us to debug your problem with the
information you provided?

Why so offensive?

I expect nothing!
I ask for help, if you dont want to, then dont.

Anyway...

Which PyOSC? There seem to be quite a few out in the wild ...

I am reffering to this version of PyOSC:
https://gitorious.org/pyosc/devel/commits/python3

What event loop do you use in your program? Some code please ... Cheers ,Ralf Mattes

I have a python3 app, that calls a class OSC_Communication.

address = localhost, port = 9001

class OSC_Communication(object):

def __init__(self, address, port):

        self.osc_server = ForkingOSCServer((address, port))
        self.register_osc_callbacks()
    #__________________________________________________________________________________________________

    def register_osc_callbacks(self):
        self.osc_server.addMsgHandler("/test", self.test_callback)
        self.osc_server.addDefaultHandlers("", "/info", "/error")

        print ("Registered Callback-functions are :")
        for addr in self.osc_server.getOSCAddressSpace():
            print (addr)
    #_________________________________________________________________________________________________

    def test_callback(self, path, tags, args, source):
        print("test")
    #__________________________________________________________________________________________________

as simple as it is, it does not receive any OSC message.
The addressing is correct and the messages are sent.
I checked with puredata and printed messages correctly.
Wireshark captured messages correctly as well.

So, what am I missing?

Regards,
Ck
