GPRS AT commands
Modem compatible PDP context activation
Preceding PDP context activation
If setting up a call with defined QoS and PDP context parameters, the following AT
commands can be used as described in "Discrete PDP context activation".
Example: AT+CGDCONT=1,IP,volume.d2gprs.de
OK
AT+CGQREQ=1,3,4,3,0,0
OK
ATD*99***1#
CONNECT
~ }#+!}!}#} }9}"}&} }*} } }'}"}(}"}%}&µ-r#}#}%-#}%*,~~ }#
No preceding PDP context activation
The series of discrete AT commands can be replaced by the ATD command.
Example: ATD*99#
CONNECT
~ }#+!}!}#} }9}"}&} }*} } }'}"}(}"}%}&µ-r#}#}%-#}%*,~~ }#
Shutting down the connection
The GPRS data connection can be shut down in the Dial-Up Network by selecting the
hang up button. However the PDP context is still alive. It can be stopped with the AT
command AT+CGACT.
Example: AT+CGACT=0,<cid>
OK
When detaching with the AT+CGATT command, no GPRS data connection is possible
before reattaching.
Example: AT+CGATT=0,<cid>
OK
NOTE
The CGATT command also performs a PDP context deactivation, if the context had
not been deactivated before.
Another alternative is the ATH command, which closes a data connection, deactivates the
PDP context and detaches the modem.
Example: ATH
NOTE
ATH closes all ongoing voice and data connections.
