2.5.7.4 +CGDCONT - define PDP context
+ CGDCONT – define PDP context
Execute command
Read command
AT+CGDCONT?
Returns the current settings for each defined context in the format:
+CGDCONT : <cid>,<PDP_type>,<APN>,<PDP_addr>,
<d_comp>,<h_comp>,<pd1> [,…[,pdN]]]]]]]]]
Write command
AT+CGDCONT = [<cid>
[,<PDP_type>
[,<APN>[,<PDP_addr>,
<d_comp>
[,<h_comp>[,<pd1>
[,…[,pdN]]]]]]]]]
The command specifies PDP context parameter values for a PDP
context identified by the (local) context identification parameter,
<cid>
Parameters:
<cid> (PDP Context Identifier) : a numeric parameter which specifies
a particular PDP context definition. The range of permitted values
(minimum value = 1) is returned by the test form of the command.
<PDP_type> (Packet Data Protocol type) : a string parameter which
specifies the type of packet data protocol
"IP" - Internet Protocol
"PPP" - Point to Point Protocol
<APN> (Access Point Name) : a string parameter which is a logical
name that is used to select the GGSN or the external packet data
network.
If the value is null or omitted, then the subscription value will be
requested.
<PDP_address>: a string parameter that identifies the terminal in
the address space applicable to the PDP. The allocated address may be
read using the +CGPADDR command.
<d_comp>: a numeric parameter that controls PDP data compression
0 - off (default if value is omitted)
1 - on
<h_comp>: a numeric parameter that controls PDP header
compression
0 - off (default if value is omitted)
1 - on
<pd1>, … <pdN>: zero to N string parameters whose meanings are
specific to the <PDP_type>
Test command
AT+CGDCONT=?
Returns values supported as a compound value
Example
AT+CGDCONT?
+CGDCONT: 1, ”IP”, ”uni.tim.it”, ”10.10.10.10”,0,0
