After you have started GPRS dial-up by clicking on the
Dial
button,
the
Pre-Dial Terminal Screen
will be displayed. See figure here
below.
Activate by right-click the opened
Pre-Dial Terminal Screen
screen
and type the command
AT+CGATT=1
on the black screen input field.
The GPRS attach is triggered by using this AT Command.
The user can check whether the TANGO is GPRS attached by
entering:
AT+CGREG?
which is the counter-part command of
AT+CREG?
(GSM attachment status).
There are three possible response of TANGO:
+CGREG:0,1
means the TANGO is successfully attached.
+CGREG:0,0
means the TANGO is trying to attach.
+CGREG:0,2
has failed to attach and stopped trying to attach.
This occurs approx. within 1-3 min of powering up.
Alternatively, the registration status can be retrieved using:
AT+CGATT?
There are two possible response of TANGO:
+CGATT:1
means the MS is successfully attached.
+CGATT:0
means the MS is not attached, or has failed to attach.
This command is somewhat less accurate than
AT+CGREG?.
If the TANGO Modem is attached to the GPRS Network the user have
to click the
Continue
button, the other steps have to done. Normally,
if everything is going smoothly the TANGO modem within 2 or 3
seconds will be able to build a connection to the Internet.
