IGMP timeout bug - UDP multicast messages being blocked?
Posted: Tue May 01, 2018 4:01 am
I'm working on the standard SDK, and seeing an issue with UDP multicast messages not being received after around 4mins, more specifically about 4:20 - 4:40sec.
I've first suspected my router, which I do think if part of the problem but not entirely the culprit after reading this thread http://doityourselfchristmas.com/forums ... 42038.html .
I'm using the espconn_igmp_join((ip_addr_t *)&host_ip,(ip_addr_t *)&multicast_ip); function, but something is not right.
Anyone discovered anything in regards to this type of problem to help me out? Unicast works like a dream, but I need to get multicast working just as well.
