Re: [lwip-users] Recv en socket TCP

[Oscar F]

Hello and what advise do you recommend me? because i don´t understand that the other socket recv works without problem and recive the packet. do you known that can i read for learning about of this, because is my firast time using lwip and i suppossed that using the function BSD i don´t have any problem and work. 
for example i don´t know if i using correctly the file of configuration lwipopts.h

In the other case don´t block here, the cause of problem is other that i don´t identify

The call to sys_sem_signal() seems to be where it is blocking, but that
function shouldn't block.  Perhaps this is down to the implementation of
the sys layer in your port, rather than lwIP itself.
