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? Thanks, Manfred
