You should be able to tell who drops the connection and why by adding
breakpoints at the proper points in your application.
No, there is no time limit in lwIP (afaik)
You don't use sockets, do you use Netconn or do you use RAW API ?
NO_SYS = ?
If you happen to use the RAW API, you have to call tcp_close() to close
the connection, and you will either meet an err!= ERR_OK in your
tcp_recv() callback or a call to your tcp_err() callback functions.
192.168.111.2.64321 is sending a RST to 192.168.111.254.33890...
Aha, and those guys are ?
Do you know your kit is not actually resetting itself by a watchdog
timeout or ... ?
Is that RST spontaneous or in response to a sent packet ? (seems to be
spontaneous as you comment...) Can you post a wireshark capture file if
former siggestions don't hit the nail ?
