3.6 Attaching to the HSDPA or GPRS Network

After PIN authentication, the HC15 module automatically tries to attach to the HSDPA or, accordingly,

GPRS network.

3.7 Defining the PDP Context

Use the AT+CGDCONT command to configure the correct provider settings. The PDP context is

stored non-volatile.

Write command:

AT+CGDCONT=<cid>[, <PDP_type>[, <APN>[, <PDP_addr>]]]

The focus of this document is only on the parameters <cid>, <PDP_type> and <APN>. The string

parameters must be enclosed in quotation marks.

Under Windows XP, the PDP context can, optionally, be entered on the Modem property page as

described in Section 2.6.

AT+CGATT?

+CGATT: 1

Querying the current service state.

The ME is attached, depending on the selected

network type (see AT+COPS), it is either attached

to the HSDPA or GPRS service.

AT+CGDCONT?

+CGDCONT: 1,"IP","internet.t-mobile","",0,0

Specifying the PDP context (example shows the

APN of the German network provider T-Mobile).
