Establishing GPRS connection
[b][red]This message was edited by weicco at 2003-5-13 2:52:22[/red][/b][hr]
I'm working on a project which has to establish GPRS connection with AT commands. Software is supposed to run on Windows CE.
I have written a small terminal software and I can send AT commands to modem and read responses. Everything works fine, I can make calls and send SMS stuff and things like that.
But now I'm facing problems with GPRS. I've managed to set correct settings with AT+CGDCONT message and I can set up somekind of connection with AT+CGATT & AT+CGDATA. I get an IP address from the other end and things look to go well. But when I open browser (IE) it gives me an error that it can't make connection to server. I go to Internet Options, set connection to GPRS, try again and still not connection to server. Any ideas what goes wrong in here or am I totally missing something?
Then I tried another approach (or I don't know if this really is another approach, I'm not really familiar with GPRS). I send ATD*99# to modem (*99# is the number I'm supposed to call). Modem tells me CONNECT 57600 and gives unsoliticied result code +CREG: 1,1 (connection to home network). But after few seconds I get NO CARRIER message. Is there something I must send after CONNECT xxx part or what?
Any answers and ideas are greatly appreciated.
EDIT: I did some research and came to conclusion that I need to alter routing table. Am I right?
