Hi All,
I am working on a project where I need to monitor an equipment status remotely & upload the same to a web server hosted on internet.
For this, I have already designed a Atmel 89S52 with as RS232 interface to a GSM modem module.
Now the workflow is as follows,
1. Sensor connected to the microcontroller board will sense status of the equipment
2. Microcontroller pulls this info & need to push it to the GSM/GPRS modem module
3. GSM/GPRS module need to call the web server URL in following format,
http://mywebserver/datadump....&status=on
(device=motor&status=on are the 2 variables I am capturing & need to push the same to my server)

Now I am struck at the place where I am trying to push the data from my GPRS module in the above format since there is no AT command reference available for the same.

Please help me to write the AT commands for the same. Or also let me know if there are any other alternative method to push these strings to the web server in any other formats.

Here is the AT command sequence I am trying,
-----------------------------------------------------------
AT+CSTT="www","",""
OK
AT+CIICR
OK
AT+CIFSR
AT+CIPSTART=”TCP”,”172.186.142.112”,”80”
==>Here I get Error, If I get Ok than I am supposed to continue further. But even the below commands also does not provide me the facility to push the data in the format I need<== I need help here!!
CONNECT OK
AT+CIPSEND
> test APN // Ctrl Z
-----------------------------------------------------------------

Thanks in advance to all for help
