1. Introduction
1.1. Scope of this document
This document describes the messages exchanged between an external
application module and the WAVECOM GSM mobile station, based on AT
commands in order to control incoming and outgoing calls.
This document presents the AT-commands implemented for the voice
call teleservice, the data teleservice and the short message teleservice.
1.2. Related documents
This interface specification is based on the following recommandations :
[1] ETSI GSM 07.05 : Digital cellular telecommunications system

1.4. Definitions
In the GSM vocabulary, a call from GSM mobile to the PSTN is named
"mobile originated call" (MOC) or "outgoing call", and a call from fixed network
to a GSM mobile is called "mobile terminated call" (MTC) or "incoming call".
AT commands interface

2. AT commands features
2.1. Wavecom line settings
Serial link handler is set to default values (factory settings) :
autobaud, 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 start with AT (means ATtention !) and finish with a
<CR> character.
2.3. Information responses and result codes
Responses start and end with <CR><LF>, except with the ATV0 (DCE
response format) and ATQ1 (result code suppression) commands.
• If the syntax of the command is wrong, the string ERROR is sent.
• If the syntax command is correct but with some incorrect parameters,
the string +CME ERROR : <Err> or +CMS ERROR : <SmsErr> is sent with
different error codes.
• If the command line has been performed successfully, the string OK is
sent.
In some cases like "AT+CPIN?", "AT+EXPKEY?", or incoming events
(unsolicited) the module does not finish its response with the string OK.
In the following examples <CR> and <CR><LF> will be intentionally
omitted.

3. General behaviors
3.1. SIM Insertion, SIM Removal
The SIM card Insertion and Removal procedures are supported. These
are software functions based on the reading of the hardware SIM presence
pin. This pin state (open / closed) is watched continuously.
When the SIM presence pin indicates a presence of a card in the SIM
connector, the module tries to establish a logical SIM session. Depending if
the somewhat is a SIM Card or not, the logical SIM session will be
established or not. The AT+CPIN? delivers the following answers :
- If SIM presence pin indicates “Nothing”, the answer to AT+CPIN? is
“+CME ERROR 10” (SIM not inserted)
- If SIM presence pin indicates “something”, and the inserted Card is a
SIM Card, the answer to AT+CPIN? is “+CPIN: xxx” depending of the
SIM PIN state.
- If SIM presence pin indicates “something’, and the inserted Card is
not a SIM Card, the answer to AT+CPIN? is CME ERROR 10
- These both last status are not immediately available due to
background initialisation. Between the hardware SIM presence pin
indication of “something” and the previous results the AT+CPIN?
sends “+CME ERROR: 515” (Please wait, init in progress)
When the SIM presence pin indicates an absence, if a SIM Card was
inserted before, an IMSI detach procedure is done, and all the user data are
removed from the module (Phonebooks, SMS etc.). The module is then in
emergency mode.

3.2. Backgroung initialisation
After PIN entry, some SIM user data files are loaded in the module
(Phonebooks, SMS status …), but it can take a long time for huge
phonebooks reading. The AT+CPIN? command answers just after verification
of the PIN. User Datas are loaded after the answer in background.
This mean, that some datas may not be available just after the OK from
PIN Entry. Reading of phonebooks will then be refused by the following
“+CME ERROR: 515” or “+CMS ERROR: 515” meaning “please wait, service
is not available, init in progress”.
That kind of answer may be sent by the module at several steps :
- When trying to execute another AT command before the end
(response) of the previous one.
- when swapping from (or to) ADN to (or from) FDN and trying to read
immediately the concerned phonebook ;
- when asking for +CPIN? Status just after a SIM insertion when the
module has not determined that the inserted card is a valid SIM Card.

4.10. Power off +CPOF
This specific command stops the GSM software stack and then the
hardware layer. The AT+CFUN=0 command is equivalent to +CPOF
Application to GSM AT+CPOF stop GSM stack
GSM to application OK Command valid
4.11. Set phone functionality +CFUN
This command selects the level of functionality in the mobile station.
• When the application wants to stop the module for making a power off,
or if the application wants to force the module for executing a IMSI DETACH
procedure, then it has to send :
AT+CFUN=0 (same as AT+CPOF)
This command executes a IMSI DETACH and makes a backup of some
internal parameters in the SIM and the EEPROM. Then no access to the SIM
card is possible.
If the mobile is not powered off after this command, it shall received
another command to re-start the whole GSM process.
If the mobile is turned off after this command, then the power on will
automatically execute the start of the whole GSM process.
When the application wants to re-start the module (after having done a
AT+CFUN=0 command, and without having cut the power supply), it has to
send :
AT+CFUN=1
This command starts again all the GSM stack and GSM functionality, a
complete software reset is done. All parameters are reset to their previous
E2P value if AT&W was not used.
If you write entries in phonebook (+CPBW) and then reset the module
directly (AT+CFUN=1, without any AT+CFUN=0 before), some entries may
not be written (SIM task does not have the time to write entries in SIM card)

Also, the OK response will be sent at the last defined baud rate defined
by +IPR command. With autobauding the response can be at a different
baud rate, so it is better to save the defined baud rate with AT&W before
directly send the AT+CFUN=1 command.

ATD> mem <n> [I / i] [G/g] [;]
ATD> <PhbIndex> [I / i] [G/g] [;]
ATD <GSM sequence>
The ATD command is used to establish a speech, data or fax call.
According to GSM 02.30, dial command also controls supplementary
services.
For a data or fax call, the application sends to the GSM module the
following ASCII string : (the bearer has to be selected before with the +CBST
command)
ATD<nb> where <nb> 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<nb>; where <nb> is the called phone number.
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 :
ATD+33146290800;
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 13
Notice that some country can have particular numbering rules for their
GSM handset numbering.
The answer to the ATD command can be one of the following ones:
Verbose result code Numeric (V0 set) Description
OK 0if the call succeeds, for voice call
only
CONNECT <speed> 10,11,12,13,14,15
if the call succeeds, for data calls
only, <speed> takes the value
negotiated by the GSM module.
BUSY 7If the called party is already in
communication
NO ANSWER 8If no hang up is detected after a fixed
network time-out
NO CARRIER 3Call setup failed or remote user
release. Use the AT+CEER
command to know the failure cause
See paragraph 16.8 for the description of all numeric result codes
(ATV0)
Direct dialling from a phonebook location (stored in SIM card) can be
done with the following command :
ATD> <index>; for calling <index> from the selected phonebook (by
+CPBS command)
ATD> "BILL"; for calling "BILL" from the the selected phonebook
ATD> mem <index> (mem is “SM”, “FD” or “ON”, see +CPBS
command) is a way to directly dial from a phonebook number.

GSM to application OK Call succeeds
When FDN phonebook has been locked only the numbers beginning
with the digits of FDN phonebook entries can be called.
For example, if “014629” is written in the FDN phonebook all the phone
numbers beginning with these 6 digits can be called.
It’s allowed to override the CLIR supplementary service subscription for
this call only.
“I” means “invocation” (restrict CLI presentation)
“i” means “suppression” (allow CLI presentation).
It's allowed to control the CUG supplementary service information by
“G” or “g” for this call only. The index and info values set with command
+CCUG are used.
An outgoing call attempt could be refused if the AOC service is active
and the credit is expired (NO CARRIER)
When trying to make an outgoing call while there is an active call, the
active call is first put on hold, then the call setup is made.
According to GSM 02.30, GSM sequences may be controlled using dial
command. These sequences can contain “*”, “#”. But “;” is forbidden.
If the sequence is not supported or fails, +CME ERROR: <err> is
returned.
See paragraph 16.11 to have the list of supported sequences.

6.2. Operator selection +COPS
To select the operator, three possibilities exist :
1- 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.
2- 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 search automatically another network.
3- The mobile enters the manual/automatic mode, and then try to find
an operator which is indicated by the application (like in manual mode) . If this
attempt fails the automatic mode is entered.
Read command returns the current mode and the currently selected
operator. Just notice that in manual mode, this PLMN could not be the one
the mobile has to register (searching phase).
To force an attempt to select and register a network operator, the
application must send the following command :
Command syntax:

7. Security commands
7.1. Enter PIN +CPIN
This command is used to enter ME passwords (CHV1 / CHV2 / PUK1 /
PUK2…) which are needed before any other functionality of the ME can be
used. The CHV1/CHV2 length is between 4 and 8 digits, the PUK1/PUK2
length is 8 digits only.
If the user application try to establish an outgoing call before having
validated the SIM PIN code (CHV1), then the GSM module will refuse the
"ATD" command with a "+CME ERROR: 11" (SIM PIN required).
It's up to the application to validate the PIN after each reset or power on
if the PIN was enabled. The application shall therefore use the command :
AT+CPIN=<pin>
Application to GSM AT+CPIN=1234 enter PIN
GSM to application OK PIN code is correct
Application to GSM AT+CPIN=5678 enter PIN
GSM to application +CME ERROR: 3 operation not allowed, PIN previously entered
After 3 unsuccessful codes, the PUK will then be required. The PUK
validation forces the user to enter as a second parameter a new PIN code
which will be the new PIN code if the PUK validation succeeds. The CHV1 is
then enabled if the PUK1 is correct. The application shall therefore use the
command :
AT+CPIN=<Puk>,<NewPin>
Application to GSM AT+CPIN=00000000,1234 enter PUK and new PIN
GSM to application +CME ERROR: 16 Incorrect PUK
Application to GSM AT+CPIN=12345678,1234 enter PUK and new PIN, 2nd attempt
GSM to application OK PUK correct, new PIN stored
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 36
To know which code has to be entered (or not), the following
interrogation command can be used :
AT+CPIN?
The possible responses are :
+CPIN: READY ME is not pending for any password
+CPIN: SIM PIN CHV1 is required
+CPIN: SIM PUK PUK1 is required
+CPIN: SIM PIN2 CHV2 is required
+CPIN: SIM PUK2 PUK2 is required
+CPIN: PH-SIM PIN SIM lock (phone-to-SIM) is required
+CPIN: PH-NET PIN Network personnalisation is required
+CME ERROR: <err> SIM failure (13) absent (10) etc...
Please note that in this case the mobile does not finish its response with
the OK string.
The response +CME ERROR : 13 (SIM failure) is returned after 10
unsuccessful PUK presentations. The SIM card is then out of order and shall
be replaced by a new one.
Example : 3 failed PIN validations + 1 successful PUK validation
AT+CPIN?
+CPIN: SIM PIN Read the PIN status
The GSM module requires SIM PIN
AT+CPIN=1235
+CME ERROR: 16 First attempt to enter a SIM PIN
Bad PIN
AT+CPIN=1236
+CME ERROR: 16 Second attempt
Bad PIN
AT+CPIN=1237
+CME ERROR: 16 Third attempt

+CPIN: SIM PUK Read PIN state
The GSM module requires PUK
AT+CPIN=99999999,5678
OK The PUK is entered, the new PIN shall be
5678 PUK validation is OK. New Pin is 5678
AT+CPIN?
+CPIN: READY Read PIN state
GSM module is ready
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 37
If the user try to do something which requires PIN2 (CHV2) the GSM
module will refuse his action with a “+CME ERROR: 17” (SIM PIN2 required).
Then the GSM module is waiting SIM PIN2 to be given.
Of course if SIM PIN2 is blocked , SIM PUK2 is required instead of SIM
PIN2.
For instance, the GSM module needs PIN2 to write in the fixed dialling
phonebook (FDN) , so if SIM PIN2 authentification has not been done during
the current cession the SIM PIN2 is required:
Application to GSM AT+CPBS=”FD” Choose FDN
GSM to application OK
Application to GSM AT+CPBW=5,"01290917",129,"Jacky"
write in FDN at location 5
GSM to application +CME ERROR:17 SIM PIN2 is required
Application to GSM AT+CPIN?
GSM to application SIM PIN2 SIM PIN2 is required
Application to GSM AT+CPIN=5678 Enter SIM PIN2
GSM to application OK
Application to GSM AT+CPBW=5,"01290917",129,"Jacky"
write in FDN at location 5
GSM to application OK Now writing in FDN is
allowed
Please note that the GSM module ask only once PIN2 or PUK2, so if
they aren’t entered right, the next +CPIN? command will return “+CPIN:
READY”.
Remark
In the way Application to GSM, an "h" character shall be added before
the PIN value if cyphering mode (with D.E.S algorithm ) is on. See +EXPKEY
command.
Same remark for +CLCK and +CPWD commands.
7.2. Enter PIN2 +CPIN2
This specific command is used to validate the PIN2 code (CHV2), or to
validate the PUK2 code (UNBLOCK CHV2) and to define a new PIN2 code.
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 38
Of course +CPIN command allows to validate PIN2 or PUK2 codes but
only when the last executed command resulted in PIN2 authentification
failure.
The PIN2 length is between 4 and 8 digits, the PUK2 length is 8 digits
only.
AT+CPIN2=<pin2>
Application to GSM AT+CPIN2=1234 enter PIN2
GSM to application OK PIN2 code is correct
Application to GSM AT+CPIN2=5678 enter PIN2
GSM to application +CME ERROR: 3 operation not allowed, PIN2
previously entered
After 3 unsuccessful codes, the PUK2 will then be required. The PUK2
validation forces the user to enter as a second parameter a new PIN2 code
which will be the new PIN2 code if the PUK1 validation succeeds. The
application shall therefore use the command :
AT+CPIN2=<puk2>,<NewPin2>
Application to GSM AT+CPIN2=00000000,1234 enter PUK2 and new PIN2
GSM to application +CME ERROR: 16 Incorrect Password (PUK2)
Application to GSM AT+CPIN2=12345678,1234 enter PUK2 and new PIN1, 2
nd
attempt
GSM to application OK PUK2 correct, new PIN2 stored
To know which code has to be entered (or not), the following
interrogation command can be used :
AT+CPIN2?
The possible responses are :
+CPIN2: READY No PIN2 is needed
+CPIN2: SIM PIN2 PIN2 is required
+CPIN2: SIM PUK2 PUK2 is required
+CME ERROR: <err> Absent (10) etc...
AT commands interface

7.3. PIN remaining attempt number +CPINC
This specific command instructs the module to display the number of valid tries for PIN1
(CHV1), PIN2 (CHV2), PUK1 (UNBLOCK CHV1) and PUK2 (UNBLOCK CHV2) identifiers.
Command syntax : AT+CPINC
Response syntax : +CPINC : <n1>,<n2>,<k1>,<k2>
<n1>, <n2> are the remaining tries of PIN1, PIN2 (0 = blocked, 3 max)
<k1>, <k2> are the remaining tries of PUK1, PUK2 (0 = blocked, 10 max)
To make it running, the card should be present at the initialisation time,
in the opposite case, an error will be sent (+CME ERROR : 10).
Application to GSM AT+CPINC Ask remaining tries
GSM to application +CPINC : 2,3,10,10 First CHV1 attempt was a failure
Application to GSM AT+CPINC? Ask current values

9.4. Preferred Message Format +CMGF
The formats implemented are the text mode and the PDU mode.
In PDU mode, a complete SMS Message including all header information
is passed as a binary string (in hexadecimal format, so only this set of
characters is allowed : {‘0’,’1’,’2’,’3’,’4’,’5’,’6’,’7’,’8’,’9’, ‘A’, ‘B’,’C’,’D’,’E’,’F’} ).
Each pair or characters is converted to a byte (ex : ‘41’ is converted to the
ASCII character ‘A’, whoes ASCII code is 0x41 or 65).
In Text mode, every commands and responses are in ASCII characters.
The chosen format is stored in EEPROM by the command +CSAS.
Application to GSM AT+CMGF ? current message format
GSM to application +CMGF: 1
OK Text mode
Application to GSM AT+CMGF=? Possible message format
GSM to application +CMGF: (0-1)

PDU mode, no SC address
GSM to application +CMGS: 4
OK MSG correctly sent, <mr>
is returned
The message <pdu> is composed of the SC address (« 00 means no SC
address given, use default SC address read with +CSCA command) and the
TPDU message.
The length of octets of the TPDU buffer is 14, coded as GSM 03.40
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 55
In this case the TPDU is : 0x01 0x03 0x06 0x91 0x21 0x43 0x65 0x00
0x00 0x04 0xC9 0xE9 0x34 0x0B, which means regarding GSM 03.40 :
<fo> : 0x01 (SMS-SUBMIT, no validity period)
<mr> (TP-MR): 0x03 (Message Reference)
<da> (TP-DA) : 0x06 0x91 0x21 0x43 0x65
(destination address +123456)
<pid> (TP-PID): 0x00 (Protocol Identifier)
<dcs> (TP-DCS): 0x00 (Data Coding Scheme : 7 bits alphabet)
<length> (TP-UDL): 0x04 (User Data Length, 4 characters of text)
TP-UD : 0xC9 0xE9 0x34 0x0B (User Data : ISSY)
TPDU in hexadecimal format must be converted into two ASCII
characters, e.g. octet with hexadecimal value 0x2A is presented to the mobile
as two characters ‘2’ (ASCII 50) and ‘A’ (ASCII 65).
9.5. Save Settings +CSAS

This command shall be used to select value for the <vp>, <pid>, the
<dcs>. The application must send the following command :
Command syntax : AT+CSMP=<fo>, <vp>, <pid>,<dcs>
<fo> byte is composed of 6 differents fields :
b7 b6 B5 b4 b3 b2 b1 b0
RP UDHI SRR VPF RD MTI
RP : Reply Path, not used in text mode.
UDHI : User Data Header Information, b6=1 if the beginning of the User
Data field contains a Header in addition to the short message. This option is
not supported in +CSMP command, but can be used in PDU mode (+CMGS).
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 65
SRR : Status Report Request, b5=1 if a status report is requested. This
mode is supported.
VPF : Validity Period Format
b4=0 & b3=0 -> <vp> field is not present
b4=1 & b3=0 -> <vp> field is present in relative format
Others formats (absolute & enhanced) are not supported.
RD : Reject Duplicates, b2=1 to instruct the SC to reject an SMS-
SUBMIT for an SM still held in the SC which has the same <mr> and the
same <da> as the previously submitted SM from the same <oa>.
MTI : Message Type Indicator
b1=0 & b0=0 -> SMS-DELIVER (in the direction SC to MS)
b1=0 & b0=1 -> SMS-SUBMIT (in the direction MS to SC)
In text mode <vp> is only coded in "relative" format. The default value is
167 (24 hours). This means that one octet can describe different values :
VP value Validity period value
0 to 143 (VP + 1) x 5 minutes (up to 12 hours)
144 to 167 12 hours + ( (VP - 143) x 30 minutes )
168 to 196 (VP - 166) x 1 day
197 to 255 (VP - 192) x 1 week
<pid> is used to indicate the higher layer protocol being used or
indicates interworking with a certain type of telematic device. For example,
0x22 is for group 3 telefax, 0x24 is for voice telephone, 0x25 is for ERMES.
<dcs> is used to determine the way the information is encoded. UCS2
alphabet and compressed text are not supported. Only GSM default alphabet
and 8 bit data are supported.
Application to GSM AT+CSMP? current values

Application to GSM AT+CMGD=3 Delete it
GSM to application OK Message deleted
9.16. Service center address +CSCA
This command shall be used to indicate to which service center the
message has to be sent.
The GSM module has no default value for this address. If the application
tries to send a message without having indicated the service center address,
an error will be generated.

Command syntax: AT+CSCB= <mode>, [ <mids>, [ <dcss> ] ]
Set command selects which types of CBMs are to be received by the
ME, This command is allowed in both PDU and text modes.
The <bm> parameter of +CNMI command controls the message
indication.
Test read command (AT+CSCB ?) is not supported.
The activation of CBM reception (<mode>=0) can select only specific
Message Identifiers (list in <mids>) for specific Languages (list in <dcss>), but
the deactivation stops any reception of CBMs (only AT+CSCB=1 is allowed)
Message Identifiers (<mids> parameter) indicates which type of
message identifiers the ME should listen to.
Supported languages (<dcss> parameter) are : 0 for German, 1 for
English, 2 for Italian, 3 for French, 4 for Spanish, 5 for Dutch, 6 for Swedish,

incompatible (1)
Note 1 : The accepted status changes are from READ to NOT READ
and vice versa, and from SENT to NOT SENT and vice versa.
If all the parameters are correct, the module overwrites the whole SMS in
the SIM. Only the first byte (Status byte) is changed.
9.20. Message overwriting +WMGO
The +CMGW writes a SMS to the first free location. To write a SMS to a
specified location, the +WMGO specific command forces the module to write
a SMS (with +CMGW command) to the location specified with +WMGO, but
just for one +CMGW command.
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 69
Command syntax : AT+WMGO= <loc>
<loc> location number of the SIM record to write or overwrite
Possible responses:
OK if <loc> is a valid SMS location, for AT+WMGO=? and
for AT+WMGO?
+CMS ERROR: 321 if <loc> is out of the SIM capacity range.
+WMGO: <loc> for AT+WMGO?
Then on the next AT+CMGW commnand, the used record number will
be that one specifed by AT+WMGO command. The location is then forgotten,
and to make a second overwrting, the +WMGO shall be used again.
If the external application specifies a free location, and if an incoming
message is received before the AT+CMGW command, the module may store
the incoming message in a free location, which could be unfortunately the
one specified by +WMGO (the module does not prevent this case). Then if
the user issues a AT+CMGW command, without changing the AT+WMGO
location, the new message will be overwritten !
Be aware that this location number is not kept over a software reset.

10.15. Unstructured supplementary service data +CUSD
The USSD supplementary service is described by the GSM 02.90.
It is based on digit sequences which may be entered by mobile user with
an handset. An entered sequence is sent to the network which answers back
with a alphanumerical string, only for display, or to display and to ask for a
next sequence.
This command is used for :
-enabling or disabling the CUSD indication sent to the
application by the module when a incomming USSD is
received
-send and receive USSD strings.
For the first behavior, the syntax is :
Command syntax:
AT+CUSD = <n> [ ,<str> [ <dcs> ] ]
<n>
0 : Disable the result code presentation
1 : Enable the result code presentation
2 : Cancel session (not applicable to read command response)
In case of presentation enabled, a +CUSD (as direct answer to a send
USSD) is then indicated with :
+CUSD: <m> [,<str>,<dcs> ]
- <m> :
0no further user action required (network initiated
USSD-Notify, or no further information needed after mobile
initiated operation)
1further user action required (network initiated

a different way. For outgoing call the two parameters (e.g. <speed> and
<ce>) apply, whereas for incoming call only the <ce> parameter applies.
Note 1) as far as incoming calls are concerned, if <ce> is set to T only
and the network proposes NT only or vice versa then the call is released.
Note 2) older values 100 and 101 for <ce> are retained for compatibility
purpose but shallnot be used anymore, values 2 and 3 shall be used instead.

Application to GSM AT+IPR=?
GSM to application +IPR:(0,2400, 4800, 9600, 19200) ,
(300,600,1200,38400,57600,115200)
OK
possible values (1)
Application to GSM AT+IPR=38400
GSM to application OK disable autobauding and set
rate to 38400 bps
Application to GSM AT+IPR=0
GSM to application OK enable autobauding
Note (1) : first set of values indicates the range of autodetectable
speeds. The second set of values indicates all the possible speeds which can
be used by DCE.
An autobauding is provided which operates from 2400 to 19200 baud.
However some constraints have to be dealt with :
• any AT command issued by DTE must start with a capital ‘A’ and ‘T’
(or ‘\’). If not, DCE may send back some garbagge characters and get
de-synchronized. Shoud it happen, DTE shall just issue once or twice
‘AT\r’ (at 2400 or 4800 baud) or just ‘AT’ (at 9600 baud) to get the
modem re-synchronized.
• the DTE shall wait for 1ms after receipt of the last character of the AT
response (which is always ‘\n’ or 0x0A) to send a new AT command at
either the same rate or a new rate. Shoud this delay ignored, DCE
can get de-synchronised. Once again, sending once or twice ‘AT\r’ or
just ‘AT’ causes the DCE to recover.
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 97
Be careful : at start-up if autobauding is enabled and no AT command
has been received yet, the module sends all unsolicited responses (like
RING) at 9600 baud.
13.2. DTE-DCE character framing +ICF
This command is used to determine the local serial port start-stop
(asynchronous) character framing that the DCE shall use.
Command syntax: AT+ICF= <format>, <parity>
* <format> :
0Autodetect not supported
18 Data 2 Stop supported
28 Data 1 Parity 1 Stop supported
38 Data 1 Stop supported
47 Data 2 Stop supported
57 Data 1 Parity 1 Stop supported
67 Data 1 Stop supported
* <parity> :
0Odd supported
1Even supported
2Mark supported
3Space supported
4None supported
Note 1) setting a character framing different from 8N1 will disable
autobauding (in the case it was activated). However setting it back to 8N1 will
not re-enable autobaud.
Note 2) setting the framing to 8N1 will let the autobauding enabled, if it
was already enabled (implying framing was already 8N1).

13.3. DTE-DCE local flow control +IFC
This command is used to control the operation of local flow control
between the DTE and DCE.
AT+IFC=<DCE_by_DTE>,<DTE_by_DCE>
* < DCE_by_DTE > :
0 none Supported
1Xon/Xoff local circuit 103 not supported
2RTS Supported
3Xon/Xoff global on circuit 103 not supported
Important note : when this parameter is set to 2 (DTE invokes flow
control through RTS) the behavior of the DCE is the following :
If the DCE has never detected RTS in high (or ON) condition since
startup then it ignores RTS, assuming this signal is not connected.
As soon as DCE detects RTS high, then this signal acts upon it.
Therefore subsequent RTS transition to OFF will prevent DCE from sending
any further data in online and in offline as well.
This behavior allows the user to use the default settings (hardware flow
control) and let RTS disconnected. In the case RTS is connected and is high
at least once then it acts upon DCE.

14. Specific AT commands
14.1. Cell environment description +CCED
This command can be used by the application to retrieve the cell
parameters of the main cell and of up to six neighbour cells.
Two ways may exist for the external application to know these cell
parameters : on request of the application, or automatically by the module
every 5 seconds.
The automatic mode is not supported during communication or
registration.
The command to manage this functionality is :
Command syntax: AT+CCED=<mode>[, <requested
dump>]
* <mode> :
0One shot requested
1Automatic shots requested
2Stop automatic shots
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 106
* <requested dump> :
1Main Cell :
if the Cell Identity is available
MCC, MNC, LAC, CI, BSIC, BCCH Freq (absolute), RxLev,
RxLev Full, RxLev Sub, RxQual, RxQual Full, RxQual
Sub,Idle TS
if the Cell Identity is not available
MCC, MNC, LAC,, BSIC, BCCH Freq (absolute), RxLev,
RxLev Full, RxLev Sub, RxQual, RxQual Full, RxQual
Sub,Idle TS
2Neighbour1 to Neighbour6 :
if the Cell Identity is available
MCC, MNC, LAC, CI, BSIC, BCCH Freq (absolute), RxLev
if the Cell Identity is not available
MCC, MNC, LAC,, BSIC, BCCH Freq (absolute), RxLev
4Timing Advance
Combination (addition of the values) of the requested dumped are
supported.
Notice that in idle mode, only RxLev measures (one the main cell and on
the neighbour cells) are done. The value of these RxLev is set in the RxLev
Full field for the main cell.
The response will be :
+CCED :<value>, ... , <value>
OK
Where <value> is the ASCII string of the values (in decimal except LAC
and CI values are in hexadecimal) of the parameters. If a field can not be
measured - or has no sense - the parameter is not filled (two consecutive
commas are then found).
If the <requested dump> parameter is absent, this of the last +CCED
command (or 15 by default) will be taken.
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 107
Values of MCC/MNC are set to 0 in case of “No service”
14.2. Automatic RxLev indication +CCED
The CCED command has been extended to indicate the the received
signal strength indication (rssi) of the main cell. The principle of the command
is not changed :
Command Syntax: AT+CCED=<mode>[, <requested
dump>]
* <mode> :
0One shot requested
1Automatic shots requested
2Stop automatic shots
* <requested dump> :
8Main cell RSSI indications (RxLev) from 0 to 31
The response will be a +CSQ answer and not a +CCED answer. The
07.07 format for the +CSQ is respected. The <ber> is not evaluated by this
command, so the <ber> value will always be 99.
+CSQ :<rssi>, 99
OK
This +CSQ answer, when automatic shots are selected, is sent every
time the <rssi> measured by the module changes. This automatic shots are
supported in idle mode and during communication.
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 108
Combination (addition of the values) of the requested dumped (1,2,4,8)
are supported. Both answer +CCED and +CSQ may be then generated.
If the <requested dump> parameter is absent, this of the last +CCED
command (or 15 by default) will be taken.
14.3. General Indications +WIND
Wavecom introduced a general mechanism to send unsollicited non
standardized indication to the customer application. The yet identified
unsollicited non standardized indications are :
- indication of a physical change on the SIM presence pin from
connector (meaning SIM inserted, SIM removed)
- indication during a mobile originated call establishement, that the
calling party is ringing.
- Indication of the availability of the module, after boot, to receive AT
commands
For each of these indications, a “bit flow” has to be indicated. The syntax
of the command is :
Command syntax: AT+WIND= <IndLevel >
<IndLevel> Indication
1 (bit-0) Hardware SIM Insert / Remove indications (Rack open/close)
2 (bit-1) Calling party alert indication
4 (bit-2) Module is ready to treat AT commands (except phonebooks,
AOC, SMS), but still in emergency mode.
8 (bit-3) Indication that the module is ready to treat all AT commands,
at te end of init, or after ADN / FDN swap
16 (bit-4) Indication that a new call identifier has been created ( after an
ATD command, +CCWA indication)
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 109
32 (bit-5) Indication that an active, held or waiting call has been released,
If <IndLevel> is equal to 0 (default value), no unsolicited
“+WIND: <IndNb>” will occur.
Combination (addition of the values) shall be used to allow more
than one indication flow.
0 W IndLevel W 63
The answer is OK if the value are in the previous range.
The unsolicited answer will then be :
+WIND : <event> [ ,<idx> ]
<idx>: Call identifier, defined in +CLCC command.
The supported events are:
<event> Meaning
0The SIM presence pin has been detected as “SIM removed”
(depending from the 0 bit flow)
1The SIM presence pin has been detected as “SIM inserted”
2Calling party is alerting
3Module is ready to treat AT commands (except phonebooks, AOC,
SMS), at init or after AT+CFUN=1
4Module is ready to treat all AT commands, end of phonebook init
or swap (FDN to ADN)
5Call <idx> has been created (after ATD, RING or +CCWA…)
6Call <idx> has been released, after a NO CARRIER, a +CSSU: 5
indication, or after the release of a call waiting
AT commands interface

AT+WIND? Command is supported and indicates the <allowed bit
flows>. AT+WIND is automatically stored in e2p. This means the &W
commands has not to be used. And the selected flows are always activated
after boot.
Default value is 0 : No flow activated. No indication.
AT+WIND=? Indicates the posibbles values. (0-63)
14.4. Data ciphering mode between ME and MSC +ALEA

16.6. GSM 04.11 Annex E-2: Mobile originating SM-transfer
These error causes could appear for SMS commands (+CMGS, +CMSS, +CMGD…)
Cause no 1: "Unassigned (unallocated) number"
This cause indicates that the destination requested by the Mobile Station cannot be
reached because, although the number is in a valid format, it is not currently assigned
(allocated).
Cause no 8: "Operator determined barring"
This cause indicates that the MS has tried to send a mobile originating short message
when the MS's network operator or service provider has forbidden such transactions.
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 122
Cause no 10: "Call barred"
This cause indicates that the outgoing call barred service applies to the short
message service for the called destination.
Cause no 21: "Short message transfer rejected"
This cause indicates that the equipment sending this cause does not wish to accept
this short message, although it could have accepted the short message since the equipment
sending this cause is neither busy nor incompatible.
Cause no 27: "Destination out of service"
This cause indicates that the destination indicated by the Mobile Station cannot be
reached because the interface to the destination is not functioning correctly. The term "not
functioning correctly" indicates that a signalling message was unable to be delivered to the
remote user; e.g., a physical layer or data link layer failure at the remote user, user equipment
off-line, etc.
Cause no 28: "Unidentified subscriber"
This cause indicates that the subscriber is not registered in the PLMN (i.e. IMSI not
known)
Cause no 29: "Facility rejected"
This cause indicates that the facility requested by the Mobile Station is not supported
by the PLMN.
Cause no 30: "Unknown subscriber"
This cause indicates that the subscriber is not registered in the HLR (i.e. IMSI or
directory number is not allocated to a subscriber).
Cause no 38: "Network out of order"
This cause indicates that the network is not functioning correctly and that the
condition is likely to last a relatively long period of time; e.g., immediately reattempting the
short message transfer is not likely to be successful.
Cause no 41: "Temporary failure"
This cause indicates that the network is not functioning correctly and that the
condition is not likely to last a long period of time; e.g., the Mobile Station may wish to try
another short message transfer attempt almost immediately.
Cause no 42: "Congestion"
This cause indicates that the short message service cannot be serviced because of
high traffic.
Cause no 47: "Resources unavailable, unspecified"
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 123
This cause is used to report a resource unavailable event only when no other cause
applies.
Cause no 69: "Requested facility not implemented"
This cause indicates that the network is unable to provide the requested short
message service.
Cause no 81: "Invalid short message transfer reference value"
This cause indicates that the equipment sending this cause has received a message
with a short message reference which is not currently in use on the MS-network interface.
Cause no 95: "Invalid message, unspecified"
This cause is used to report an invalid message event only when no other cause in
the invalid message class applies.
Cause no 96: "Invalid mandatory information"
This cause indicates that the equipment sending this cause has received a message
where a mandatory information element is missing and/or has a content error (the two cases
are undistinguishable).
Cause no 97: "Message type non-existent or not implemented"
This cause indicates that the equipment sending this cause has received a message
with a message type it does not recognize either because this is a message not defined or
defined but not implemented by the equipment sending this cause.
Cause no 98: "Message not compatible with short message protocol state"
This cause indicates that the equipment sending this cause has received a message
such that the procedures do not indicate that this is a permissible message to receive while in
the short message transfer state.
Cause no 99: "Information element non-existent or not implemented"
This cause indicates that the equipment sending this cause has received a message
which includes information elements not recognized because the information element identifier
is not defined or it is defined but not implemented by the equipment sending the cause.
However, the information element is not required to be present in the message in
order for the equipment sending the cause to process the message.
Cause no 111: "Protocol error, unspecified"
This cause is used to report a protocol error event only when no other cause applies.
Cause no 127: "Interworking, unspecified"
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission 124
This cause indicates that there has been interworking with a network which does not
provide causes for actions it takes; thus, the precise cause for a message which is being send
cannot be ascertained.
All values other than specified should be treated as error Cause No 41
