1 Introduction
1.1 Scope of the document
This document presents the AT Commands Set for Quectel cellular engine M10.
1.2 Conventions and abbreviations
In this document, the GSM engines are referred to as following terms:
 ME (Mobile Equipment)
 MS (Mobile Station)
 TA (Terminal Adapter)
 DCE (Data Communication Equipment)
 Facsimile DCE(FAX modem, FAX board)
In application, controlling device controls the GSM engine by sending AT Command via its serial
interface. The controlling device at the other end of the serial line is referred to as following terms:
 TE (Terminal Equipment)
 DTE (Data Terminal Equipment)
 Plainly "the application" which is running on an embedded system
1.3 AT Command syntax
The "AT" or "at" prefix must be set at the beginning of each command line. To terminate a
command line enter <CR>. Commands are usually followed by a response that includes
"<CR><LF><response><CR><LF>". Throughout this document, only the responses are
presented, “<CR><LF>” are omitted intentionally.
The AT Command Set implemented by M10 is a combination of GSM07.05, GSM07.07 and
ITU-T recommendation V.25ter and the AT Commands developed by Quectel.
All these AT Commands can be split into three categories syntactically: "basic", "S parameter",
and "extended". They are listed as follows:
 Basic syntax
These AT Commands have the format of "AT<x><n>", or "AT&<x><n>", where "<x>"is the
command, and "<n>"is/are the argument(s) for that command. An example of this is "ATE<n>",
which tells the DCE whether received characters should be echoed back to the DTE according to
the value of "<n>". "<n>" is optional and a default will be used if missing.
 S parameter syntax
These AT Commands have the format of "ATS<n>=<m>", where "<n>" is the index of the S

register to set, and "<m>"is the value to assign to it. "<m>" is optional; if it is missing, then a
default value is assigned.
 Extended syntax
These commands can operate in several modes, as following table:
Table 1: Types of AT Commands and responses
Test Command AT+<x>=? This command returns the list of parameters and value
ranges set with the corresponding Write Command or
by internal processes.
Read Command AT+<x>? This command returns the currently set value of the
parameter or parameters.
Write Command AT+<x>=<…> This command sets the user-definable parameter
values.
Execution Command AT+<x> This command reads non-variable parameters affected
by internal processes in the GSM engine
1.3.1 Combining AT Commands on the same command line
You can enter several AT Commands on the same line. In this case, you do not need to type the
"AT" or "at" prefix before every command. Instead, you only need type "AT" or "at" at the
beginning of the command line. Please note to use a semicolon as command delimiter.
The command line buffer can accept a maximum of 256 characters. If the characters entered
exceeded this number then none of the command will be executed and TA will return "ERROR".
1.3.2 Entering successive AT Commands on separate lines
When you need to enter a series of AT Commands on separate lines, please note that you need to
wait the final response (for example OK, CME error, CMS error) of last AT command you entered
before you enter the next AT command.
1.4 Supported character sets
The M10 AT Command interface defaults to the IRA character set. The M10 supports the
following character sets:
 GSM format
 UCS2
 HEX
 IRA
 PCCP437
 8859_1
The character set can be set and interrogated using the "AT+CSCS" command (GSM 07.07).
The character set is defined in GSM specification 07.05.

The character set affects transmission and reception of SMS and SMS Cell Broadcast Messages,
the entry and display of phone book entries text field and SIM Application Toolkit alpha strings.
1.5 Flow control
Flow control is very important for correct communication between the GSM engine and DTE. For
in the case such as a data or FAX call, the sending device is transferring data faster than the
receiving side is ready to accept. When the receiving buffer reaches its capacity, the receiving
device should be capable to cause the sending device to pause until it catches up.
There are basically two approaches to achieve data flow control: software flow control and
hardware flow control. M10 support both two kinds of flow control.
In Multiplex mode, it is recommended to use the hardware flow control.
1.5.1 Software flow control (XON/XOFF flow control)
Software flow control sends different characters to stop (XOFF, decimal 19) and resume (XON,
decimal 17) data flow. It is quite useful in some applications that only use three wires on the serial
interface.
The default flow control approach of M10 is hardware flow control (RTS/CTS flow control), to
enable software flow control in the DTE interface and within GSM engine, type the following AT
command:
AT+IFC=1, 1
This setting is stored volatile, for use after restart, AT+IFC=1, 1 should be stored to the user
profile with AT&W.
Ensure that any communications software package (e.g. ProComm Plus, Hyper Terminal or
WinFax Pro) uses software flow control.
Note:
Software Flow Control should not be used for data calls where binary data will be transmitted or
received (e.g. TCP/IP) as the DTE interface may interpret binary data as flow control characters.
1.5.2 Hardware flow control (RTS/CTS flow control)
Hardware flow control achieves the data flow control by controlling the RTS/CTS line. When the
data transfer should be suspended, the CTS line is set inactive until the transfer from the receiving
buffer has completed. When the receiving buffer is ok to receive more data, CTS goes active once
again.
To achieve hardware flow control, ensure that the RTS/CTS lines are present on your application
platform.

1.6 Unsolicited Result Code
A URC is a report message sent from the ME to the TE. An unsolicited result code can either be
delivered automatically when an event occurs, to reflect change in system state or as a result of a
query the ME received before, often due to occurrences of errors in executing the queries.
However, a URC is not issued as a direct response to an executed AT command. AT commands
have their own implementations to validate inputs such as "OK" or "ERROR".
Typical URCs may be information about incoming calls, received SMS, changing temperature,
status of the battery etc. A summary of URCs is listed in Appendix A.
When sending a URC the ME activates its Ring Interrupt (Logic "l"), i.e. the line goes active low
for a few milliseconds. If an event which delivers a URC coincides with the execution of an AT
command, the URC will be output after command execution has completed.

Note:
 Parameter "I" and "i" only if no *# code is within the dial string.
 <n> is default for last number that can be dialed by ATDL.
 *# codes sent with ATD are treated as voice calls. Therefore, the
command must be terminated with a semicolon ";".
 See ATX command for setting result code and call monitoring
parameters.
Responses returned after dialing with ATD
 For voice call two different responses mode can be determined. TA
returns "OK" immediately either after dialing was completed or after
the call is established. The setting is controlled by AT+COLP. Factory
default is AT+COLP=0, this cause the TA returns "OK" immediately
after dialing was completed, otherwise TA will returns "OK",
"BUSY", "NO DIAL TONE", "NO CARRIER".
Using ATD during an active voice call:
 When a user originates a second voice call while there is already an
active voice call, the first call will be automatically put on hold.
 The current states of all calls can be easily checked at any time by
using the AT+CLCC command.

Response
This command is only available during TA is in data mode, such as, a CSD
call, a GPRS connection and a transparent TCPIP connection. The "+++"
character sequence causes the TA to cancel the data flow over the AT
interface and switch to command mode. This allows you to enter AT
command while maintaining the data connection to the remote server or,
accordingly, the GPRS connection.
OK
To prevent the "+++" escape sequence from being misinterpreted as data, it
should comply to following sequence:
1. No characters entered for T1 time (0.5 seconds).
2. "+++" characters entered with no characters in between. For CSD call
or PPP online mode, the interval between two "+" MUST be less than 1
second and for a transparent TCPIP connection, the interval MUST be
less than 20 ms.
3. No characters entered for T1 time (0.5 seconds).

Note:

 If a fixed baud rate is set, make sure that both TE (DTE, usually
external processor) and TA (DCE, Quectel GSM module) are
configured to the same rate. If autobauding is enabled, the TA could
automatically recognize the baud rate currently used by the TE after
receiving “AT” or “at” string.
 The value of AT+IPR can’t be restored with AT&F and ATZ, but it is
still storable with AT&W and visible in AT&V.
 In multiplex mode, the baud rate can’t be changed by the write
command AT+IPR=<rate>, and the setting is invalid and not stored
even if AT&W is executed after the write command.
 A selected baud rate takes effect after the write commands is executed
and acknowledged by “OK”.

2.2.43.1 Autobauding
To take advantage of autobauding mode specific attention must be paid to the following
requirements:
 Autobauding synchronization between TE and TA
− Ensure that TE and TA are correctly synchronized and the baud rate used by the TE is
detected by the TA. To allow the baud rate to be synchronized simply use an “AT” or
“at” string. This is necessary after customer activates autobauding or when customer
starts up the module with autobauding enabled.
− It is recommended to wait for 2 to 3 seconds before sending the first “AT” or “at” string
after the module is started up with autobauding enabled. Otherwise undefined characters
might be returned.
 Restriction on autobauding operation
− The serial interface shall be used with 8 data bits, no parity and 1 stop bit (factory
setting).
− The command “A/” can’t be used.
− Only the string “AT” or “at” can be detected (neither “AT” or “at”).
− URCs that may be issued before the TA detects a new baud rate by receiving the first AT
character, and they will be sent at the previously detected baud rate.
− If TE’s baud rate is changed after TA has recognized the earlier baud rate, loss of
synchronization between TE and TA would be encountered and an “AT” or “at” string
must be re-sent by TE to regain synchronization on baud rate. To avoid undefined
characters during baud rate re-synchronization and the possible malfunction of
resynchronization, it is not recommended to switch TE’s baud rate when autobauding is
enabled. Especially, this operation is forbidden in data mode.
 Autobauding and baud rate after restarting.
− In the autobauding mode, the detected baud rate is not saved. Therefore,
resynchronization is required after restarting the module.
− Unless the baud rate is determined, an incoming CSD call can’t be accepted. This must
be taken into account when autobauding and auto-answer mode (ATS0 ≠ 0) are
enabled at the same time, especially if SIM PIN 1 authentication is done automatically
and the setting ATS0 ≠ 0 is stored to the user profile with AT&W.
− Until the baud rate is synchronized, URCs after restarting will not be output when
autobauding is enabled.
 Autobauding and multiplex mode
If autobauding is active it is not recommended to switch to multiplex mode.
 Autobauding and Windows modem
− The baud rate used by Windows modem can be detected while setting up a dial-up
GPRS/CSD connection. However, some Windows modem drivers switch TE’s baud rate
to default value automatically after the GPRS call is terminated. In order to prevent no
response to the Windows modem when it happens, it is not recommended to establish the
dial-up GPRS/CSD connection in autobauding mode.
− Based on the same considerations, it is also not recommended to establish the FAX
connection in autobauding mode for PC FAX application, such as WinFax.
NOTE:
To assure reliable communication and avoid any problem caused by undetermined baud rate

between DCE and DTE, it is strongly recommended to configure a fixed baud rate and save
instead of using autobauding after start-up.

Reference Note:
 The automatic URC is reported about every 5 seconds when
<mode>=2.
 The parameter <lac> and <cellid> are presented as hexadecimal digits;
the remaining parameters are composed of decimal digits.
 If a field cannot be measured, the parameter is filled with character ‘x’.
 If not in dedicated mode, <tch>, <ts>, <maio>, <hsn>, <ta>,
<rxq_sub>, <rxq_full> are not valid and are displayed as "x".
 If the network supports frequency hopping during a connection, the
TCH channel is not stable. This mode is indicated by <tch> = ‘h’.
 In dedicated mode, the parameters <c1> and <c2> of main cell can not
be updated and are displayed as an invalid value ‘-1’. At the same time,
the parameters <txp> and <rla> cannot be updated under certain
conditions and remain the value of idle mode. This is because the ME
does not update the cell selection and reselection parameters since, in
this mode, they are not relevant for operation. When the connection
ends, and the mobile is back to idle mode, correct values will be given.
 If TA reports neighbouring cells description, the information of 6 cells
are presented and if some cells can not be measured, ‘x’ is filled in the
parameters of these cells.
 In dedicated mode, the parameters <c1> and <c2> of neighbour cells
may be measured and reported with a meaningless value, and the
parameters <mcc>, <mnc>, <lac> and <cellid> of neighbour cells can
not be measured, ‘x’ is filled in these parameters of all the 6 neighbour
cells.
 The command does not report receiving level and reserving quality,
and AT+CSQ can be used to retrieve the two parameters.
