Hi,

I use vodafone (on a GM862 and GE864) here in Australia. The following is the sequence that I use to get to a Web Page:-

AT#GPRS=1 //This replies with my IP number I do not even need to specify the apn

AT#SKTD=0,80,“www.theage.com.au” //the 80 is for port 80 the HTML port - replies with connect

GET / HTTP/1.0 //don’t forget cr lf at the end

//needs another cr lf at the end

Then down comes the HTML from the web - it disconnects at the end but I just redo the socket dial - NOT the GPRS = 1

Hope it helps.

Thank you Sir I’ll try your sequence

I’ve noticed a similar problem with the 865 QUAD. If I use the newer command set, AT#SGACT=1,1 followed by AT#SD=1,0,80,“some host” the module will hang and give no CONNECT or ERROR. If I use the older commands, AT#GPRS=1 followed by AT#SKTD=0,80,“some host” it connects just fine. If I +++ escape out and then use the multisocket AT#SD version, it works just fine. Seems like the older commands are initializing something that the new commands are not? Has anyone else experienced this?

I found my Ge865 did the same thing, I could not get a CONNECT response even though I could see my Apache server was serving the requested page back.

I found that if I disable flow control with a AT&K=0 then suddenly I see the CONNECT and my html stuff.

I am using vodafone prepaid in Brisbane Aus.

AT+CGDCONT=1,"IP","vfinternet.au",0.0.0.0
AT#USERID=""
AT#PASSW=""
AT#GPRS=1
AT#SKTD=0,80,"google.com"

i am having problems sending an email. I used these

AT#ESMTP=“smtp.live.com”

OK

AT#EADDR=“*****@hotmail.com”

OK

AT#EUSER=“*******@hotmail.com”

OK

AT#USERID=“**********”

OK

and then i tried to send the email. but got an error. I do have an active gprs connection.
