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
