I have some problem with downloading files from server.
Do anyone knows what does mean log tcp_recved:(in LWIP comopnent);
esspecialy the last value in (ZZZ)
I think that wnd does mean size availe window_buffor for TCP;
tcp_recved: received XXX bytes, wnd YYYY, (ZZZ)

Any could help me, and know what it mean?

I have problem with packet or rather fragments of packet.
for example (screen 2nd) I have recieved 11799 B of 48000.
And debug logs isn't tell me anything or I cant read logs appropriate

is ZZZ value says how many Bytes I have already read?
but it dosnt make sens becasue on 2nd picture I have 0B (0 value)

ZZZ means the data size in you WND. ZZZ = MAX WND( in your config is 44200) - current WND.
