2. AT commands features
2.1. WAVECOM line settings
Currently, WAVECOM's handler is set to 9600 bps, 8 bits data, 1 bit
stop, no parity, RTS/CTS flow control. Please use the commands +IPR, +IFC,
+ICF to change these settings.
2.2. Command line
Commands always finish with a <CR> character.
2.3. Information responses and result codes
Responses always start with <CR><LF> and end with <CR><LF>.
•If the syntax command is wrong, the string ERROR is sent.
•If the syntax command is correct but with some incorrect parameters,
the string +CME ERROR : XX is sent with different error codes.
•If the command line has been performed successfully, the string OK is
sent.
Please note that in the some cases like "AT+CPIN?", "AT+EXPKEY?",
incoming events etc... the mobile does not finish its response with the string
OK.
Examples : AT+CGSN<CR>
<CR><LF>123456789<CR><LF>
<CR><LF>OK<CR><LF>
In the following examples <CR> and <CR><LF> will be intentionally
omitted.

3. AT commands for Call Control
3.1. Dial command D
This AT command is used by the external application to establish a call.
For a data call, the application sends to the GSM module the following
ASCII string : (the bearer has to be selected before with the +CBST
command)
ATD<xyz> where <xyz> is the called phone number.
For a voice call, the application sends to the GSM module the following
ASCII string : (the bearer may be selected before, if not a default bearer is
used)
ATD<xyz>; where <xyz> is the called phone number.
The answer to the command is the following :
OK if the call succeeds, for voice call only
CONNECT <speed> if tthe call succeeds, for data call only, <speed>
takes the value negotiated by the GSM module.
BUSY if the called party is in communication
NO ANSWER if no hang up is detected after a fixed network
time-out
Please, notice that in case of international number, the local international
prefix has not to be set (usually 00) but need to be replaced by the '+'
character.
Example : to establish a voice call to Wavecom from another country,
the AT command shall be :

Wavecom GSM Modem
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 13
ATD+33146290800;
Notice that some country can have particular numbering rules for their
GSM handset numbering.
Direct dialling from a phonebook location (stored in SIM card) can be
done with the following command :
ATD>17 ; or ATD>SIM17 ; (voice call here)
3.2. Hang-Up command H
This command is used by the application to disconnect the remote user.
The application sends :
Application to GSM ATH ask for disconnection
GSM to application OK even if there is no
communication established
3.3. Answer a call A
When the GSM module receives a call, it set the RingInd signal and
sends to the application the ASCII string RING. Then it waits for the
application to accept the call.
Application to GSM ATA
GSM to application OK normal case
Application to GSM ATA
GSM to application NO CARRIER if ATA is sent when no incoming call was
indicated (operation not allowed)
3.4. Remote disconnection
This message is used by the GSM module to indicate to the application
that the communication has been released by the remote user.
The GSM module sends "NO CARRIER" to the application, and set the
DCD signal.

Wavecom GSM Modem

3.5. DTMF signals +VTD, +VTS
The GSM module offers the user application to send DTMF tones. One
command shall be used for defining the duration of the tones (default value is
70 ms), the other for sending the Tones.
For defining the duration, the application uses :
AT+VTD=<n> where <n>*100 gives the duration in ms.
Application to GSM AT+VTD=1 for defining 100 ms tone duration
GSM to application OK command valid
Application to GSM AT+VTD=100000
GSM to application +CME ERROR: 3 if the duration is too long (the limit is to
define for each application)
Application to GSM AT+VTD=0 for setting the manufacturer default value
GSM to application OK
For sending DTMF tones, the application uses :
AT+VTS=<Tone> where <Tone> is in {0-9,*,#,A,B,C,D}
Application to GSM AT+VTS=A
GSM to application OK command valid
Application to GSM AT+VTS=11
GSM to application +CME ERROR: 4 if the <Tone> is wrong
Application to GSM AT+VTS=4
GSM to application +CME ERROR: 3 if there is no communication
Exemple : to send the Tone sequence 13#, the application shall send :
AT+VTS=1 and then wait for
OK
AT+VTS=3 and then wait for
OK
AT+VTS=# and then wait for
OK

3.6. Operator selection +COPS
To select the operator, two possibilities exist :
The mobile enters the manual mode, and then try to find an operator
which is indicated by the application. If it finds and registers correctly, then
the mobile stays in idle mode.
The mobile enters the automatic mode, and then try to find the home
operator. If it finds and registers correctly, then the mobile stays in idle mode ;
if not, the mobile looks itself automatically for another network.
To force an attempt to select and register a GSM network operator, the
application must send the following command :
AT+COPS=<mode>, <format>, <oper>
The first parameter indicates either automatic (value 0) or manual
(value 1). The second parameter indicates the format of the third parameter.
The only format supported by Wavecom module is the numerical format
(value 2). The third parameter is the operator identifier (MCC3 MCC2 MCC1
MNC2 MNC1).
Application to GSM AT+COPS? ask for current plmn
GSM to application +COPS: 0,2,20801
OK Home plmn is France telecom
Application to GSM AT+COPS=? ask for plmn list
GSM to application +COPS: (2,20801), (0,20810)
OK Home plmn is France Telecom
SFR network has been seen
Application to GSM AT+COPS=1,2,20810 ask for registration on SFR network
GSM to application +CME ERROR: 3 failed
Application to GSM AT+COPS=1,1,20810 ask for registration on SFR network
GSM to application +CME ERROR: 4 wrong parameters
Application to GSM AT+COPS=0,2 ask for registration on home
network
GSM to application OK succeeded
3.7. Redial last number ATDL
This command is used by the application to redial the last number used
in the command ATD. The application sends :

Wavecom GSM Modem
