MP 700 Series GPS AT Command Reference
100 2130309
A/ Reissue last AT command
Re-executes the last command string entered. The last-executed command
remains in the command buffer until AT is entered again or the modem is reset
or power-cycled. A/ will reissue that same command. It executes immediately
when the slash (/) is entered.
Note: This command is not preceded by AT and does not require <CR> to
terminate.
A Answer incoming call (or GPRS network request)
GSM mode When operating in GSM voice, or CSD mode, ATA instructs the
modem to immediately go off-hook and attempt to establish a connection
without waiting for a ring. This is used to answer an incoming call if the auto-
answer status register (S0—see page 25) is disabled.
The command presumes a RING has been received. If the command is issued
without a RING, and the modem is in command state, the modem replies with
OK and remains in command state.
Once the RING arrives, the modem looks for carrier to negotiate the connection,
and either issues:
CONNECT and enters data state; or
NO CARRIER and remains in command state.
GPRS mode When operating in GPRS packet mode, the ATA command
answers a network request for a PDP context activation announced by the
unsolicited result code RING. The modem responds with CONNECT and enters
the V.25ter online data state to initiate a GPRS connection.
D**##[n] Make GPRS connection
Establishes a connection using the specified profile. The !MPSETUP is used to
maintain profiles; up to three profiles are supported. (See page 56.)
The GPRS profile used in the connection is specified by n:
<n>=0 Default profile. (Set by the !MPSETDFLT command.)
<n>=1 Profile 1
<n>=2 Profile 2
<n>=3 Profile 3
The connection uses the PDP context settings assigned using +CGDCONT,
+CGQMIN, and +CGQREQ to the PDP Context Identifier 1. (That is, the <cid>
must be 1. D**## cannot be configured to use any other value for the <cid>.) In
order to establish a connection with specific QoS (Quality of Service) settings,
or header or data compression settings, the settings must be assigned to PDP
Context Identifier 1 (<cid>=1) using the +CGDCONT, +CGQMIN, and
+CGQREQ commands.
