I'm working on a webserver application, and I use the lwip 1.4.1 tcp/ip stack. I'm working on STM32F407 device. I implemented the binary file upload, but sometimes when I try to upload the files, get TCP retransmission and TCP Dup Ack error on network capture. Sometimes the file upload was succesfully and somtimes wasn't. Can You tell me somebody why it's caused? I didn't find the right solution up to now.
The two captures(one when the upload was succesfully, one when wasn't) is available at this link.
Please use the following filter to see the captures between my PC and my device: ip.addr == 192.168.0.23
Please help me. Kind regards, Szabolcs
