Hi, apparently I am missing something else.
I can find devices when connected to a 'regular' LAN.
However, I have a camera that creates a Wifi accesspoint and makes itself discoverable via SSDP. Once I connect to this accesspoint my computer gets a valid IP address assigned and the NodeJS code is able to discover the device. Unfortunately, the Pharo snippet I posted before does not give me any results and hangs in Socket>>waitForDataIfClosed: .
Any further ideas?
Are you sure you restarted the image and your code after switching networks ?
I did not check this before. But I just downloaded a fresh 40613 image with PharoLauncher and started it after connecting to the camera accesspoint. The code snippet freezes there as well.

I don't know then, I used the UDP stuff before in various applications and it worked fine. Just like with all networking code, you sometimes get in a stuck state when developing (i.e. running incomplete code). Getting stuck means you are waiting forever for an answer that is not coming.
From a distance I can't help much more, just double check that your initial message is completely correct and that you send it to the right host:port.
