dear all, i want to send a packet more than 1500 bytes, in my case is 2048 bytes, after sending i see the below message:
Sending data... tcp_write(pcb=4000a718, data=400057a4, len=2048, apiflags=1) tcp_enqueue(pcb=4000a718, arg=400057a4, len=2048, flags=0, apiflags=1) tcp_enqueue: queueing 6511:7971 (0x0) tcp_enqueue: queueing 7971:8559 (0x0) tcp_output_segment: 6511:7971 0:.tcp_write(pcb=4000a718, data=400057a4, len=952, apiflags=1) tcp_enqueue(pcb=4000a718, arg=400057a4, len=952, flags=0, apiflags=1) tcp_enqueue: queueing 8559:9511 (0x0) tcp_output_segment: 7971:8559 this mean that i sent 2048 bytes successfully already, but when i use wireshark application (network analyzer application) i only see a packet with 588-byte length sent. I changed MTU (netif->mtu) from 1500 to 3000 and SND_BUF, TCP_MSS, TCP_SND_BUF, TCP_WND, ETH_FRAG_SIZE, ETH_MAX_FLEN from 1500 to 3000 as well. Anyone know how to do it? please advise thank you very much. Thien
