Hi

I’m using lwip 1.3.0 and updated to 1.3.1 and found problem with window size

I receive small blocks of data (30 bytes) every 500 ms and on each I call
tcp_recved()

On version 1.3.0 the window size on tcp ack is 512 (what is my maximum), 

but for version 1.3.1 the window size Is decreased with the received 30
until the size is less and it wait short time,

after that the window size is 512 again and it continue. This is repeated
the hole time (I’m using the same application)

 

Anyone know what the problem is, I call  tcp_recved() on each received block

 

Med vänliga hälsningar/Best Regards

Jan Wester
