Stm32f4 use lwip clients, communicate with Linux server problem

Time:01-27

Currently using stm32f407, TCP/IP protocol stack (version for V1.3.2), as a TCP client; Server for ubuntu10.04 version of PC,
In order to clearly describe the problem called the PC's, called the stm32 C
Problems are as follows:
1: after send packages to C 1 S, C protocol stack will not reply 1 ACK to the pack, in order to be able to let the normal communication, that S not retransmission packets 1, lead to die after a period of time the client C, the solution for C will receive the package 1 is returned immediately,


2: for S and C for communication, S to 1 S for the cycle of probe packets sent to C, C immediately after received reply, each run more than about 10 minutes the client will receive less than data,

3: when the server S on ubuntu14.04, and when the client remains the same, test more than 10 hours is no problem,
