Set command specifies GPRS PDP context parameter values for a GPRS PDP
context identified by the (local) context identification parameter, <cid>
Parameters:
<cid> - (GPRS PDP Context Identifier) numeric parameter which specifies a
particular PDP context definition.
1..max - where the value of max is returned by the Test command
<PDP_type> - (Packet Data Protocol type) a string parameter which specifies the
type of packet data protocol
"IP" - Internet Protocol
“IPV6” - Internet Protocol, Version 6(Not supported)
<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_addr> - 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> - numeric parameter that controls PDP data compression
0 - off (default if value is omitted)
1 – on
2 - V.42bis
<h_comp> - numeric parameter that controls PDP header compression
0 - off (default if value is omitted)
1 – on
2 - RFC1144 (applicable for SNDCP only)
3- RFC2507
4- RFC3095 (applicable for PDCP only)
<pd1>, …, <pdN> - zero to N string parameters whose meanings are specific to the
<PDP_type>
Note: a special form of the Set command, +CGDCONT=<cid>, causes the values
for context number <cid> to become undefined.
Note: +CGDCONT command permit define 3 PDP Context Ids at the same time.
AT+CGDCONT?
Read command returns the current settings for each defined GPRS context in the
format:
+CGDCONT: <cid>,<PDP_type>,<
APN>,<PDP_addr>,<d_comp>,
<h_comp>[,<pd1>[,…[,pdN]]][<CR><LF>+CGDCONT: <cid>,
<PDP_type>,<APN>,<PDP_addr>,<d_comp>,<h_comp>
[,<pd1>[,…[,pdN]]][…]]
