Hi, in my tests the following problem occurs: A packet with the same sequence number was sent to lwIP. Wireshark TCP analysis says it was a TCP Retransmission with same sequence number and same data (plus a little bit more data append to the earlier transmitted data).
My question: What will be happen in lwIP in tcp_receive() ? I have seen in this function that a sequence analysis will be done. But I do not understand it? I will understand what is given by lwIP to my receive callback function? For instance the following frames are sent by : - Frame 1 with some data of length 100 bytes, e.g. AABBCCDD..YYZZ - Frame 2 consists of data of Frame 1 (100 bytes) + new data (50 bytes) = 150 bytes, e.g. AABBCCDD..YYZZ001122.. Can I ignore Frame 1 and take only Frame 2? Give lwIP both frames or only the second frame? Thanks for any help.
