Sorry, *fix the devices*. IPv6 must work and that's not up for discussion. You could use that excuse in 10 years ago, not in 2018. The router is not an issue because we're talking about local network traffic only. The router is not involved. If, however, you have a Level 3 switch that is dropping certain packets, then fix them because it's interfering with legitimate traffic. If it blocks IPv6, it may block other things, including the IPv4 multicast CoAP requests that you would otherwise need (that's exactly what happens at our offices with the WiFi). > > > For > > > the question if the packets go out on IPv4, so in the first 5 > > > minutes i can't see them only after. > > How did you test this?

Please test this on actual device, with actual network and actual applications. I need you to run tcpdump on the sender device and start it before you launch the IoTivity application. > Also when i am using IPv6 the multicast message will work straight after > starting the iotivity. It could be simply because IPv6 gets address assignment very quickly (stateless) whereas IPv4 needs to wait for DHCP. Please confirm that the network interface had IP addresses assigned before the IoTivity application launched. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ iotivity-dev mailing list iotivity-dev@lists.iotivity.org https://lists.iotivity.org/mailman/listinfo/iotivity-dev
