Hi All,
I'm having trouble with controlling the SYN re-transmit timeout. My platform (NXP-LPC1837) connects to an application on windows, every once in a while the windows IP-stak doesn't respond to the SYN. The TCPNET stack re-transmits the SYN packet. The only problem I have with this is that the timeout between the SYN re-transmission is uncontrollable.
e.g.: First SYN at 0 secs Second SYN is at 58.6 seconds Third SYN is at 165.48 seconds SYN ACK at 165.48 seconds
I checked the tick function settings and timer tick, these are correct. I checked the SYN timeout: #define TCP_SYN_RETRY_TOUT 2 /* TCP SYN frame retransmit period in sec. */
Any suggestions would be greatly appreciated.
Thanks, Dennis
