OnCell G2150I AT Command Set GPRS Commands

AT +CGATT=1

OK

Defined values: <state>: indicates the state of GPRS attachment

•0: detached

•1: attached

•2: combined detach (GPRS and GSM detach in the same network request)

•Other values are reserved and will result in an ERROR response to the execution command.

PDP Context Activate or Deactivate: +CGACT

Description: The execution command is used to activate or deactivate the specified PDP context(s). After the command has completed, the MT remains in V.25ter 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 MT is not GPRS attached when the activation form of the command is executed, the MT first performs a GPRS attach and then attempts to activate the specified contexts. If the attach fails then the MT responds with ERROR, or if extended error responses are enabled, with the appropriate failure-to-attach error message. If no <cid>s are specified the activation form of the command activates the first possible within the defined contexts. If no <cid>s is specified the deactivation form of the command deactivates all active contexts. One PDP contexts can be activated through MOXA software at the same time. The read command returns the current activation states for all the defined PDP contexts. The test command is used for requesting information on the supported PDP context activation states.

Command syntax:

Command	Possible responses
AT+CGACT=[<state> [,<cid>[,<cid>[,…]]]]	OK
	ERROR
AT+CGACT?	+CGACT: <cid>, <state>
	[<CR><LF>+CGACT: <cid>, <state>
	[...]]
	OK
AT+CGACT=?	+CGACT: (list of supported <state>s)
	OK
AT +CGACT=1,1	OK
AT+CGACT?	+CGACT: 1, 1
	OK
AT+CGACT=?	+CGACT: (0-1)
	OK

Defined values:

<state>: indicates the state of PDP context activation

‧0: deactivated

‧1: activated

‧Other values are reserved and will result in an ERROR response to the execution

command.

<cid>: a numeric parameter that specifies a particular PDP context. Before the activation of the context, the MT has to attach itself to the GPRS network if necessary.

Note: if a GPRS PPP session is already running, the setting of a CSD (GSM data call) is not supported.
