Neither the recv.go nor Wireshark filtering "udp.dstport == 5566" receving any package.

I understood what is happening

It's the arg of URI
For example:
The interface you wish to broadcast is eth0, which assigned you with an IP "10.5.4.152"

❌ epgm://eth0;239.0.0.1:5566
❌ epgm://239.0.0.1:5566
✔️ epgm://10.5.4.152;239.0.0.1:5566
