[lwip-users] mdns responds when connected as udp, but not to multicast received on network

[transistorman]

Hello,
I am debugging mdns. If I use a ncat terminal and send a packet on port 5353
to my Atmel SAM E70 board, the CPU gets to the breakpoint I put in
mdns_recv(void *arg, struct udp_pcb *pcb, struct pbuf *p, const ip_addr_t
*addr, u16_t port). When I see mdns packets on the network with Wireshark,
the handler never gets called.

I initialize the code with:
mdns_resp_init();
mdns_resp_add_netif(netif, "myname", 3600);


Also, am I supposed to see an mdns broadcast transmitted periodically? I
don't seem to see any portion in the code that does that.
Frank
