I find that the udp_multicast_example.c can not recv any udp multicast packet.
It only can send packet to the multicast address.
Using wireshark we can find that the Trailer 55555.. while the other multicast app send the 60 Bytes IGMP packet with 0000.. padding.
Is there anyone success recv udp multicast on esp32?
