Hi Sergio, Thank you for the response. I had tcp_accept callback and memp_free() routine when connection was closed. I have double checked that. The problem was that my connection wasn't properly closed at both sides and when I have immediately tried to open new connection on the same port it was giving trouble.
Thank you again. Can I ask you what do you mean by this?: If you use callbacks, you are not using "a socket", I guessed you are using the RAW API with or without an OS, try to be specific on your scenario. Yes I use raw API without OS but to create a tcp connection between server and client. Each end has IP addres + port # which are the tcp socket? -- Sent from: http://lwip.100.n7.nabble.com/lwip-users-f3.html _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
