I’m having some issues to receive multicast frames with W5500.
Initialization seems to be normal but receive buffer never changes from zero.
[INFO]Global Interruptions Enabled
---------- DHCP INIT ---------
[INFO]HW ADDR: 0:8:dc:22:1:88
SOCK STATUS 0: SOCK_UDP
SOCK STATUS 1: SOCK_UDP
Socket 0 is set for UDP, port 4000 which I can receive data normally.
Socket 1 is set for UDP+MCAST, port 49707 which I cannot receive anything.
First question would be if something is being set for the intended group, and the question is yes, I sniffed w/ wireshark and the router is forwarding to the group every second:
1 0.000000 192.168.0.1 188.8.131.52 UDP 81 49707 → 49707 Len=39
Appreciate any help!
