I have a question regarding GPRS connections and the sony ericson GR47 module. I don’t think it uses the Open AT commands (I haven’t looked at them yet). But I am fairly familiar with its AT commands. Anyway…
Is this the correct place to ask this? I can make a GRPS connection using their M2M AT commands, and also make a connection using their scripting language (C look alike), however using the plain old AT commands.
AT+CGDCONT=1,“IP”,“INTERNET”
AT+CGATT=1
AT+CGREG=1
ATD99**1#
I get a “Connected” and nothing else… no PPP communications, nothing, I can’t type anything, I assume that its in data mode because I can type “+++AT” (the escape sequence) and it returns me to the AT prompt where I can type AT commands again (but all the AT commands that are to return IP addresses return nothing). I can type ATO which puts me back into online mode again.
Does anyone have any ideas? of what is possibly wrong or where I should ask this question?
