Re: RE : [lwip-users] Multi-cast UDP messages?

[Robert Morse]

Ya,
        That what I would of thought.
	I get no other messages after the lwip_sendto().  I am looking at if 
something is wrong
with the mailbox going to the TCP thread, as that is all that I can see 
it should be doing
is posting a message after that log.  I have traced to never returning 
from netconn_connect(..).

	Thanks, at least I know that the stack supports it so I will keep 
looking.
