assalamualaekum!

I am working on sim 548c and want to open a website (any website)..i followed the following set of commands for establishing connection and sending the request..

at
ok
at+cgatt=1
ok //enabling gprs
at+cgdcont=1,"IP","ufone.internet"
ok
at+cstt="ufone.internet","ufone","ufone"
ok
at+ciicr
ok
at+cifsr
ok //ip given by the service provider
at+cdnscfg="0.0.0.0"
ok
at+cdnsorip=0
ok
at+cipstart="TCP","74.125.39.147","80"

(i put in the ip of a site ,google.com)(i thought ,the ip here should be of the site we are to open or the name of the site ..please correct me if i am wrong)

-ok
-connect ok

at+cipsend
>get Google http/1.1 ^m^j^m^j^z

-send ok

but after a few seconds i get a huge data in ASCII format and on copying that in a note pad and then saving that as .html i get the following web page ..ALWAYS..


it will be very kind of you to please help me solve this issue..
i have followed the data available on this site but i couldnt get my problem solved..

Regards,
Umer
 

hi umerhuzaifa
use this
Code: 
at+cipsend
>GET https://www.google.com(cr)(lf)
Connection:Keep-Alive(cr)(lf)
(cr)(lf)(ctrl+z(0x1A))

then you got the html page
if this is not working try this

at+cipsend
>GET index.html HTTP/1.1(cr)(lf)
Host:www.google.com(cr)(lf)
Connection:Keep-Alive(cr)(lf)
(cr)(lf)(ctrl+z(0x1A))

instead of this

at+cipsend
>get Google http/1.1 ^m^j^m^j^z

but there are many websites like www.download.cnet.com and many others which dont open either
1-at at+cipstart=.. level giving an error rather than telling CONNECT OK
or
2-give html file reading 404 BAD REQUEST..
