SIM508 connection closes after CIPSEND

at+cipsend

Hi all,

I'm using SIM508 module to send information to a web server. everything is
working fine: I can start the TCP connection, send data using CIPSEND with GET
method and query string parameters and receive it on server side page,
which will respond with an OK string.
the problem is that after I receive the response from server the connection
closes: I get an CLOSED message from SIM module. this is a major problem
because the service provider will charge me a 10KB minimum for every
TCP connection.

does anyone knows why this is happening and how to solve it?

thanks

cipsend get

Ask ur server operator to increase the sleep time or closing time between each frame sending, that you do using AT+CIPSEND.
SO ask server-provider to adjust the time difference between two CIPSEND

sim508 http connection

Hi ,
I have a similar issue. How can I make my modem to re-connect UDP or TCP connections automatically after the connections are cut off?

Please help.

Thanks
