In my earlier post I pressed “Send” too early.
I experienced a bit slow, so I used Wireshark to see the communication
The Win32 simulation is quiet slow. On thing that may help is lowering the clock frequency from 1000 to 100:
#define configTICK_RATE_HZ 100U
The main purpose of the WinSim project is learning and creating demos. It is not really useful for real-life or commercial applications.
Unlike a “native” port, the WinSim port simulates everything: semaphores, tasks, clock-ticks. But it does so in a very correct way.
Have you already tried to increase the TCP WIN size?
You can set all TCP stream parameters by using FREERTOS_SO_WIN_PROPERTIES.
Have a try with these settings:
xWinProps.lTxBufSize = 8 * ipconfigTCP_MSS; /* Unit: bytes */
xWinProps.lTxWinSize = 4; /* Unit: MSS */
xWinProps.lRxBufSize = 8 * ipconfigTCP_MSS; /* Unit: bytes */
xWinProps.lRxWinSize = 4; /* Unit: MSS */
FreeRTOS_setsockopt( xSocket,
0,
FREERTOS_SO_WIN_PROPERTIES,
( void * ) &xWinProps,
sizeof( xWinProps ) );
Please set these settings right after creating a socket. You can apply it to a listening socket. Child sockets will automatically inherit all properties from the listening socket.
When using connect(), make the sockopt settings before calling connect().
If you can, please show a new PCAP file. You can use a filter ip.addr==192.168.0.251 and store with File->Store specified packets->Selected packets only. Thank you
