LWIP TCP receiving

[a8Chcx]

Hi,

I am using FRDM-K66 with LWIP stack. I have the following problems:

When I use sample TCP sever, everything works fine except the following:

If PC send TCP packet evrery 100ms, my server get zero window size in TCP. Can anyone tells me how to avoid this. Like RESET window size when detect it or speed up TCP coming process, or increasing buffer, nd etc...

Thanks,

Christie

Hello

I hope you are well.

Increasing the buffer size might be helpful.
What causes the TCP window to 0?  Usually, it comes down to performance, simple as that. The TCP receive buffer is full and it cannot receive any more data.

Best regards,
Omar
