+CGACT=
<state>,<cid>
+CGACT?
+CGACT=?
Note: The Sierra
Wireless modem permits
only one PDP context to
be active at a time.
GPRS PDP context activation/deactivation
In GPRS packet data mode, the
+CGACT
command activates (
<state>=1
) or
deactivates (
<state>=0
) the specified Packet Data Protocol (PDP) context, then
returns the modem to command state.
<cid>
(the PDP Context Identifier) is a numeric parameter which specifies a
particular PDP context definition.
+CGACT=?
returns the permitted values. (See
also +CGPADDR on page 70.)
Details
•
If the specified PDP context is already in the requested state, the state for
that context remains unchanged.
•
If the requested state cannot be achieved, the modem returns an error.
(Extended error responses are enabled by the
+CMEE
command, page 76.)
•
If the modem is not GPRS-attached when instructed to activate, it attempts
to perform a GPRS attach first. (See page 63.)
•
If no
<cid>
is specified, the command either activates the default PDP
context, or deactivates the active one, as appropriate.
•
+CGACT?
returns the current activation state for the PDP context, while
+CGACT=?
requests information on the supported PDP context activation
states.
+CGATT=<state>
+CGATT?
GPRS attach or detach
Attaches or detaches the Sierra Wireless modem from the GPRS network:
•
<state>=0
detaches from the GPRS network.
•
<state>=1
attaches to the GPRS network.
Any other values return an error.
Details
•
If the modem is already in the requested state, the command is ignored and
the modem returns an OK response.
•
Any active PDP contexts are deactivated before detaching from the GPRS
network.
•
The
+CGATT?
command returns the current GPRS-attach state of the
modem.
