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

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)
<< SEND OK

<< server send data back

Hi all,

I followed the method listed here for sending data to a webpage using sim900 modem.
After sending the data, i get response 'send ok' and data is received in webpage. but this is getting success only a few times, and i need to send the data repeatedly.

Has anyone faced this problem before? Could anyone help me to clear this problem.


Regards,
Jebin
