Hello,
I'm working with lwip and freertos on STM32.
I did a task based on sockets which is listening on multicast address.
It works when I send a multicast message from PC, and my board answer. So
far so good.
But I took a wireshark capture and lwip doesn't send an IGMP join group.
Consequence: packet from PC are sent to the entire network/switch. Then
there is no difference with a broadcast packet from my opinion.
I check in the igmp code and the program pass through the join group (
igmp_send() ) but nothing ontgoing on the network.
I think I'm not so far the solution...
thanks for your ideas,
Pierre
