Hello,

 

I've got another problem. I am receiving a large (~132 K) HTTP file via
TCP. The very first packet, which has the file length, is received, but
not ACKed. The server times out and resends this packet, which is
properly ACKed and all subsequent packets are handled properly. 

 

I had this code working a couple of months ago, and something has
changed since. I've tried changing the frequency of LWIP interrupt
handler calls, both greatly slowing and speeding them up, with no
apparent change in behavior. It's only with TCP reception in this case
that I see a problem. Other TCP exchanges work fine, with the same code
structure in the two callback functions.

 

Any ideas?
