Hi everyone, I have a system like this: STM32 Board with FreeRTOS and LWip on it (192.168.17.48). On the other side I have a QT GUI (running on Windows address 192.168.17.48) which sends TCP commands to the Board. After the communication is etsablished and some random number of packets are sent the communication between the two parties does not work. In the attachment I am sending you the obsereved packets via Wireshark. I am not an expert in LWIP at all, but from the things observed I guess either it is a timing problem (packets are send to fast and no ACK is received) or the reconnection is not successfuly established. Reseting the board helps the problem. However in the use case that I am having this should not be done.
Has anyone experianced similar problem? Do I have to change some LWIP options in the lwipopts.h file? Can someone give me tips where to look for the problem? Thank you very much in advance. Anna
