HUAWEI ME936 LTE M.2 Module
AT Command Interface Specification
Introduction
1
Introduction
1.1 Scope
This document describes AT command interface specifications that is supported by
Huawei Mobile Broadband product ME936 module.
Please read the Release Notes released with the firmware before using ME936
module and this document.
1.2 Overview
This document describes certain AT commands (implemented by terminal devices) of
international standards, according to the requirements of terminal devices. In addition,
this document describes the proprietary AT command interfaces that are implemented
by terminal devices. These proprietary AT command interfaces help implement a
certain function.
This document does not describe the interfaces that have been defined by standards
or implemented by the mobile terminal (MT) but are not required by the Huawei
terminal product. The description of AT command interfaces covers only the data
packets of interfaces, the methods and processes for the Terminal Equipment (TE)
and the MT to use interfaces, excluding the contents that are not directly related to
interfaces. In addition, this document describes only the AT command interfaces
falling within the range of Rm interfaces between the TE and MT, excluding the AT
command interfaces falling within the range of Um interfaces between the MT and
IWF.
AT commands are communication command protocols between TEs and MTs. If a
new MT is to interconnect with an existing TE implemented based on this AT
specification, the MT must comply with the specification. For example, to interconnect
with the unified background of an existing personal computer (PC), a new module
must comply with this specification. A PC application or tool must comply with this
specification to interconnect with existing terminal devices. If a TE or MT does not
communicate by using AT commands, this specification does not apply.

AT Command Interface Specification
Introduction
1.3 Organization
Chapter 2 "General Commands" to chapter 7 "Standard STK Interface Commands"
describe AT interfaces defined in international standards such as 3GPP and ITU-T.
Chapter 8 "Huawei Proprietary Interface: BodySAR Interface Description" to chapter
15 "Huawei Proprietary Interface: Customer Production Line Tests Interface" describe
Huawei proprietary interfaces.
1.4 Document Conventions
Throughout the document, the module are referred to as ME (Mobile Equipment), MS
(Mobile Station), TA (Terminal Adapter) or DCE (Data Communication Equipment). To
control your module you can simply send AT Commands via its serial interface. The
controlling device at the other end of the serial line is referred to as TE (Terminal
Equipment), DTE (Data Terminal Equipment) or plainly 'the application' (probably
running on an embedded system).
Section "Property Description" of each command marks the property of each AT
command. Where, N means No, Y means Yes and NA means Not Applicable.
For example:
Saving upon Power-off
N
PIN
Y
The settings are described as follows:
Parameter settings in the command are not saved after the MT is powered off.
This command is controlled by personal identity numbers (PINs).

Introduction
<...>:
The parameter inside these angle brackets is mandatory. The <> does
not exist in a command.
[...]:
The parameter inside these square brackets is optional. The [] does not
exist in a command or a response.
:
Carriage return character, which value is specified with command S3.
:
Line feed character, which value is specified with command S4.
According to the AT command specifications for GSM and WCDMA in 3GPP TS
27.007, there is a component named TA between TE and MT. Physically, TA can be
integrated with either TE or MT. In this document, TA is integrated with MT. In TIA/EIA
IS 707-A, TA is not specified. To simplify the description in this document, TA is
ignored. The client on a computer is treated as TE, and MT is treated as TA+MT.
Note:
If all parameters are not specified, "=" is not required.
1.5.3 AT Command Description
An AT command controls the rules for interaction between the TE such as PC and MT
such as MS. Figure 1-1 shows the interaction between the TE and MT.

1.6 Abort Attributes of AT Commands
Some action commands that require time to execute may be aborted while in progress.
Aborting of commands is accomplished by the transmission from the DTE to the DCE
of any character. A single character shall be sufficient to abort the command in
progress; however, characters transmitted during the first 125 milliseconds after
transmission of the termination character shall be ignored (to allow for the DTE to

Introduction
append additional control characters such as line feed after the command line
termination character). To insure that the aborting character is recognized by the DCE,
it should be sent at the same rate as the preceding command line; the DCE may
ignore characters sent at other rates. When such an aborting event is recognized by
the DCE, it shall terminate the command in progress and return an appropriate result
code to the DTE, as specified for the particular command.
The following commands can be aborted.
ATD
Can be aborted
AT+CLCK
Can be aborted
AT+COPS
Can be aborted except "AT+COPS=?"
1.7 Rules for Running AT Commands
1.
Each interface should be functionally convergent.
2.
Each command line contains only one AT command and ends with a carriage
return character. For the URC instruction or response reported from MT to TE,
only one AT command is allowed in a command line. In principle, users are not
allowed to run S3/S4 format modification commands. This rule is applicable to the
communication between the MT and TE programs.
3.
For an AT command that cannot be interrupted, after sending the AT command,
the TE must wait until the MT responds to the AT command before sending the
second AT command.
4.
For the AT command to which the response is given only after a long time, in
order to prevent interference on other events, it is recommended to report the
final execution result asynchronously. If the ME responds to the TE only after a
long time of waiting, the response of command may be interrupted by URC.
There are two kinds of interruption:
−
Case 1: A URC is presented when the TE is waiting for response after sending
a command. This command will be kept in waiting state until the TE finishes
receiving the URC, and then the response to this command is presented.
−
Case 2: A URC is presented when the TE is waiting for response after sending
a command. The command continues to be executed. Therefore, response to
the command may be mixed with the URC.
5.
A string refers to a byte stream (excluding the quotation marks or commas) that is
placed inside double quotation marks. Special note should be specified if the byte
stream need not be enclosed in double quotation marks.
6.
The current version does not support escape character. The code value of a data
format in the UCS2 coding is reported as characters. For example, if the UCS2
code of a Chinese character is 0x553a, the 553a is reported.
7.
A possible response sent by the MT to the TE consists of Information text and
Result code, in which Information text is optional and Result code is mandatory.
The format of a possible response is controlled by the ATV command. For details,
see the description of the ATV Command. In this document, all possible
responses listed in tables follow the ATV1 format.
8.
The meaning of the command without any parameter should be described in the
document. And it is not recommended to use the command not setting any
parameter.

character. Other character sets are listed below (only the "IRA", "GSM" and "UCS2"
character sets are supported at present):
"GSM"
GSM 7 bit default alphabet (3GPP TS 23.038); this setting causes
easily software flow control (XON/XOFF) problems.
"HEX"
Character strings consist only of hexadecimal numbers from 00 to
FF; e.g. "032FE6" equals three 8-bit characters with decimal values
3, 47 and 230; no conversions to the original MT character set shall
be done.
"IRA"
International reference alphabet (ITU-T T.50)
"PCCPxxx"
PC character set Code Page xxx
"PCDN"
PC Danish/Norwegian character set
"UCS2"
16-bit universal multiple-octet coded character set (ISO/IEC10646);
UCS2 character strings are converted to hexadecimal numbers from
0000 to FFFF; e.g. "004100620063" equals three 16-bit characters
with decimal values 65, 98 and 99.
"8859-n"
ISO 8859 Latin n (1–6) character set
"8859-C"
ISO 8859 Latin/Cyrillic character set
"8859-A"
