[lwip-devel] [bug #21307] tcp connect problem

[Simon Goldschmidt]

Follow-up Comment #1, bug #21307 (project lwip):

I tested this (since I couldn't remember how this worked): I see SYN +
SYN-ACK when entering the pcb->connected function and ACK sent after the
connected function is left. So for me, it works fine.

Can you please stop at 'tcp_ack(pcb)' (in tcp_process() right after
TCP_EVENT_CONNECTED(); I think that's the call you wanted to change to
tcp_ack_now()) and write down the pcb->flags at that time (and post them here)
to see why it doesn't send an ACK?

As I said, for me it works fine. Also, I don't think there have been any
changes in that region for some years...
