Hi, I am running a multiple connection server under lwIP 1.3.1 using raw API without an OS. Occasionally I get a problem where incoming commands from 2 clients overlap and both responses are returned to one client rather than the different clients. The command response is sent by calling tcp_write() followed immediately by tcp_output().
My question is as follows. If the first command response is processed and sent, followed very quickly by the second command response, will the second call to tcp_output() fail if the first response is still in the process of being transmitted? If this is the case what happens to the second command response that is enqueued? Will this be sent when tcp_slowtmr() is next called?
