kindly suggest lwip setting for stm32cube ide for below for receiving 14000 bytes regularly in tcp raw as client

Tcp_Wnd,

Tcp_Mss,

Pbuf_Pool_BUFSIZE

my values are-:

Tcp_Wnd=32000

Tcp_Mss,=1436

heap memory size,=45000

Pbuf_Pool_BUFSIZE=2048

i am not able to receive this packet fully it breaks in b/wsometimes receive fully?? please suggest thanks in advance

A packet of 14000 bytes cannot be received fully by STM32. This is even more than the max. jumbo packet size. It will be fragmented. Check parameters related to fragmentation.
