[lwip-users] TCP Receive Timeout
Hello all, I use LwIP version 2.0.3. I want to define timeout for TCP receive. LwIP allows to define the following options: - LWIP_TCPIP_TIMEOUT - LWIP_SO_RCVTIMEO Which of them shall be enabled for receive timeout? The timeout value shall be set by the function netconn_set_recvtimeout(). Can I use netconn_set_recvtimeout() at any time or it must be at system startup? Thanks.

I am using stm32f746 Depending on which kind of problems you see, it might be better to ask a more generic question. I don't see why IPv6 on that stm32 should be much different from any other platform.

I didn't quite get the post which seemed to suggest to increase some size, but this still seems like a driver issue. lwIP does *not* in general have problems with this! > > This seems like a high security issue.

The idea of fragmentation is that jumbo packets are split into multiple packets of 1514 bytes max each...

Hi, I've solved this issue after increasing size as was suggested here. Thanks ! (The issue was also posted here: https://community.st.com/s/question/0D50XBozSc5SQE/ethernet-fragmentation-issues) Yet, whenever lwip receives (from PC) big packet , above its limit, it gets into exception as was described above. This seems like a high security issue. Any idea how it can be solved ?
