GPRS connection problem: Can't data from a server

[tranjimmysd]

Hi,
I try to connect SIMCOM300 to TCP port 80 of a webserver using AT command throught a hyperternimal. It seems the connection is OK. The problem is when I use a simple "GET"command to request the HTTP page. I got not thing from the webserver.

OK
at+cgdcont=1,"IP","internet2.voicestream.com"
OK
AT+CSTT="internet2.voicestream.com","",""
OK
AT+CIICR
OK
AT+CIFSR
10.178.85.135
AT+CIPSTART="TCP","71.18.20.91","80" //connect to a HTTP TCP port of www.vnbtech.com
OK

CONNECT OK
AT+CIPSEND
> GET / HTTP/1.0
SEND OK


After this expect to receive the response from the server , but nothing come out to the hyperterminal.

Can you someone help me?

Thank

Hi,

These are the steps i followed to get "preference settings" from Google.

1.
at+cipstart=”TCP”,”72.14.215.99”,”80”
OK

CONNECT OK
at+cipsend
> GET /preferences?hl=en HTTP/1.1^m^j
Host: www.google.co.in^m^j^m^j^z

SEND OK

or

2.
at+cipstart="TCP","72.14.215.99","80"

OK

CONNECT OK
at+cipsend
> GET https://www.google.co.in/preferences?hl=en HTTP/1.1^m^j^m^j^z

SEND OK

I could able to check by capturing in Hyperterminal and pasting same in textpad or notepad and renaming file to .html. I could able to see most of the contents.
Even i tryied for some othe random servers and i could able to see most of the content.

Even keep tracking of posts in SIM 300: open internet site on hyperterminal
