11.22 Using GPRS AT commands (Examples)

Examples

EXAMPLE 1

Defining and using a Context Definition ID (CID):

Every time a CID is used as a parameter for a GPRS command the CID has to be defined before by using

the AT+CGDCONT command. To get the parameter of a CID use the AT+CGDCONT read option. If the response

of 'AT+CGDCONT?' is OK only, there is no CID defined.

All parameters of the CID are initiated by NULL or not present values, and the CID itself is set to be undefined.

To define a CID use the AT+CGDCONT command with at least one CID parameter. At the moment the mobile

supports CID 1 and CID 2 by using the AT+CGDCONT command.

Define CID 1 and set the PDP type to IP, access point name and IP address are not set:

Define CID 2 and sets PDP type, APN and IP addr:

A following read command will respond:

Set the CID 1 to be undefined:

A following read command will respond:

AT+CGDCONT?

There is no CID defined
