Yes.
In multicast socket, I want that WIZ750SR sends data to multicast IP and ONLY receives data on local unicast IP. I do not want that WIZ750SR receives multicast data.
The problem is, that WIZ750SR joins the multicast group and therefore receives multicast data sent from other WIZ750SR modules.
I used Wireshark to analyse the network traffic and saw that each WIZ750SR joins the multicast group and sends IGMPv2 Membership Report messages.
Is it possible to use multicast socket without joining the multicast group?
