+CGACT, PDP Context Activate or Deactivate

This command activates/deactivates the specified PDP context(s).

The following table shows the +CGACT parameters.

Command
Type Syntax Response/Action Remarks
Set AT+CGACT=[<state>
[,<cid>
[,<cid>[,]]]]
OK
or:
NO CARRIER
or:
+CME ERROR: <err>
The Set command
activates/deactivates the specified PDP
context(s). When the command is
completed, the ME remains in V.25
command state. If any PDP context is
already in the requested state, the state
for that context remains unchanged. If
the requested state for any specified
context cannot be achieved, an
ERROR or +CME ERROR response is
returned. Extended error responses are
enabled by the +CMEE command. If
the ME is not GPRS-attached when the
activation form of the command is
executed, the ME first performs a
GPRS attach and them attempts to
activate the specified contexts. If the
attach fails, the ME responds with an
ERROR or, if extended error responses
are enabled, with the appropriate
failure-to-attach error message.

activation states for all the defined
PDP contexts.
