SIM900 command for send query "GET / HTTP/1.1" to a server

Dear all
this is the first time I use SIM908
I sent data to server but I can't receive any data from the server
may help me and provide me with the AT command to received data from the server

We are a manufacturer of modem, and distributor of Wavecom module for 10 years.We hope you can tell me more about your problem and solve it together.

We have the capacity of desinging and making modem, so we also has the ability to do it.

This is how you send AT commands to SIM300 module to setup GPRS connection.


>> AT+CGATT=1 - Attach to GPRS Service
<< OK

>> AT+CGDCONT=1,"IP","<apn>" - Define PDP Context (cid, PDP type, APN)
<< OK

>> AT+CSTT="<apn>","","" - Start Task & set APN, User ID, and password
<< OK

>> AT+CIICR - Bring up wireless connection with GSM or CDS
<< OK

>> AT+CIFSR - Get Local IP address
<< 10.190.245.172
<< OK

>>AT+CIPSTATUS - Query current connection status
<< OK
<< STATE: IP STATUS

>> AT+CIPHEAD=1 - to add an 'IP Header' to receive data
<< OK

>> AT+CDNSORIP=1 - query the IP address of the given domain name
<< OK

>> AT+CIPSTART="TCP","www.india.com","80" - Start up TCP connection
<< OK
<< CONNECT OK - Indicates you've connected to the server

>> AT+CIPSEND - Issue Send Command
<< >
>> GET /testdata.php?data=Prateek HTTP/1.1 (ctrl+m)(ctrl+j)
>>HOST: www.india.com (ctrl+m)(ctrl+j) (ctrl+j)(ctrl+z)
