      violapwr if i run \example Communication/OSC-pipe/render.cpp the code runs & i'm able to receive 'osc-setup' in PD, but the 'osc-setup-reply' is not received on the Bela, with PD reporting this error send: No route to host (65)

      also can you show the Pd patch?

        @"giuliomoro"#p27136

        PD:

        this code is inside pd handshake (shown in the 2nd image):

        in pd can you use "find last error" and see where it points to?

          giuliomoro PD does not seem to be able to identify the error source, strangely:

          (in the back of my mind, I keep wondering if I messed up the system when trying to fix the git segmentation fault and need to flash the emmc (since flashing the SSD has not yet fixed it).... )

            I don't think it's a bela problem though ...
            can you try a simpler patch:

            [connect 192.168.7.2 7562(
|
| [1 2 3 4(
|/
[netsend -u -b]

            do you get the same "no route to host" error?

              giuliomoro Yes, same error. I received a successful connect (1) when clicking connect 192.168.7.2 7562. Clicking 1 2 3 4 resulted in the same error and a disconnect (0)

                giuliomoro No... I also tried to turn off my macOS firewall, and received the same error in PD

                I just tried the same experiment with my Bela Mini (and the simplified PD patch), and had the same result, which leads me to agree that the issue is perhaps not with the the Bela but on the computer end... I recently updated my macOS to 15.4... could it be a macOS issue?

                Update:
                I re-tried our PD test patch on my school computer & it worked without error (screenshot below). Also, more complex program (from a year back, above) is working as well. The school machine is macOS 14.7.5. So perhaps it's a macOS thing?

                    I don't know what they are doing that makes this stop working ... can you access the Bela IDE at 192.168.7.2?
