Best working way to connect two modems knowing their ip address is:

SERVER:
Code:
AT+CGATT=1
AT+CSNS=4
AT+CSTT="Internet","",""
AT+CIICR
AT+CIFSR
AT+CLPORT="TCP","8080"
AT+CIPSERVER
AT+CIPSEND
AT+CIPCLOSE
AT+CIPSHUT


CLIENT:
Code:
AT+CGATT?
AT+CSNS=4
AT+CSTT="Internet","",""
AT+CIICR
AT+CIFSR
AT+CIPSTART=”TCP”,”188.33.176.204”,”8080”
AT+CIPSEND
AT+CIPCLOSE
AT+CIPSHUT


Try it. Works for me on my sim300/548

----------------------------------------------
AT+CIPSTART=”TCP”,”188.33.176.204”,”8080”
where you find this IP -188.33.176.204 ?
 

hello every one
my question is how to make changes in ftp file that we want to send with sim900.
 

I have solved the GPRS connectivity problem that I was facing and the reason for my initial post... I am able to connect using GPRS and send data to my web server...
Till now I have only send data.. or text... to a server... but probably the same can be done for an image...
you need to convert the image into some stream of data and then send it...

please provide details of your problem...

Hi. I am trying to send data to my server. I am using HTTP GET request to do this. The problem is that, when I initiate the GET request using my URL of the server php page, the request is successfully submitted, but when I try to read the response from server using AT+HTTPREAD, the code hangs at that command(never comes out of the loop). I need your help. Thanks
 

Hi, my simcom sim908 was accidentally got 12v overcurrent, now it doesn't react, not even the LED blinks, on normal voltage.
Are there any chance to rekindle my sim908 to work again?
Thanks a lot!
