Hello,
after sometime of debug, i saw:
- Server send FIN, ACK after sending the packet
- which cause the connection to go to state CLOSE_WAIT
- after that i can't write to tcp_write, device dont send any more
request to a server becouse of state CLOSE_WAIT
So how to keep things alive, i tried with Keep-Alive (enabling on device
+ sending request with Connection: Keep-Alive).
So how I can maintain connection, to be able to send/recieve multiple
times ?
If anybody can please help.
Regards,
Danijel

Hello,
i have one more problem. My goal is:
- connect to server
loop
- send request (get request like
/my_php?dataFrom=[something]&dataTo=[something])
- and wait for response
while(some termination)
I did this (code below), but a second request is never sent to server.
First request id OK, i get the data in processes it ok. But at the
second request, netconn_write it seems it never send it to a server
anything (i watch with WireShark).
I tried to connect/disconnect, close - connect, but nothing worked.
So if please can anybody tell the correct procedure to send/recieve
data TCP connection.
Thanks to anybody who will even read it.
