Co., Ltd. 17 HUAWEI MU736 HSPA+ 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 terminal product MU736 module. Please read the release notes released with the firmware before using MU736 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. Issue 02 (2013-12-24) HUAWEI Proprietary and Confidential Copyright © HUAWEI Technologies Co., Ltd. 18 HUAWEI MU736 HSPA+ M.2 Module AT Command Interface Specification Introduction 1.3 Organization Chapter 2 "General Commands" to chapter 9 "Commands for Standard STK Interface" describe AT interfaces defined in international standards such as 3GPP and ITU-T. Chapter 10 "Huawei Proprietary Interface: Mobile Termination Control and Status Interface" to chapter 18 "Huawei Proprietary Interface: GPS Service Interfaces" 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 Circuit - terminating 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 PIN N 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). 1.5 AT Command Syntax 1.5.1 AT Command Types Table 1-1 Types of AT commands AT command type Sub-type Syntax General command Set command Contains one parameter: AT [= ] Contains multiple parameters: AT =[ ] Issue 02 (2013-12-24) Function A set command is executed to set parameters. HUAWEI Proprietary and Confidential Copyright © HUAWEI Technologies Co., Ltd. 19 HUAWEI MU736 HSPA+ M.2 Module AT Command Interface Specification AT command type Basic command Sub-type Syntax Execution command Contains no parameter: AT Contains one parameter: AT [= ] Contains multiple parameters: AT [= ] Introduction Function An execution command performs a specific action in addition to interacting with the local parameters of the MS. Read command AT ? A read command is executed to read the current value of a parameter. Test command AT =? A test command is executed to return the available value range of each parameter supported by the command. Basic command AT [ ] In the command format, indicates a single letter (A–Z) or the & symbol plus a single letter. In the command format, indicates a decimal number with one digit or multiple digits. The digit 0 at the start of can be ignored. S register command Read command ATS ? Returns the ASCII code of characters currently saved in the S register. The ASCII code is expressed by a 3-digit decimal number. The digit 0 is added in the front of the number in case of insufficient digits. Set command ATS = Replaces the characters saved in the S register with the characters related to the value of . 1.5.2 AT Command Parameter You are not advised to use various parameter values that are not described in this document or not supported currently as described in this document. The AT command parameters described in the following chapters are in two formats: <> and [], which are described as follows: Issue 02 (2013-12-24) HUAWEI Proprietary and Confidential Copyright © HUAWEI Technologies Co., Ltd. 20 HUAWEI MU736 HSPA+ M.2 Module AT Command Interface Specification 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. Figure 1-1 Interaction between the TE and MT AT cmds Result codes TE MT Information text Network messages USER &APPLICATIONS NETWORK Figure 1-2 shows the basic organization format of the AT command line.

Figure 1-3 shows an example of returned value of the AT command. Figure 1-3 An example of returned value of the AT command information response to +CMD2=? also string type subparameters possible information response to +CMD2? +CMD2: 3,0,15,"GSM" +CMD2: (0-3),(0,1),(0-12,15),("GSM","IRA") OK shows acceptable ranges of each subparameter final result code 1.6 Abort Attributes of AT Command 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 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 Issue 02 (2013-12-24) HUAWEI Proprietary and Confidential Copyright © HUAWEI Technologies Co., Ltd. 22 HUAWEI MU736 HSPA+ M.2 Module AT Command Interface Specification Introduction 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 Command 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.

Possible Response(s) Issue 02 (2013-12-24) HUAWEI Proprietary and Confidential Copyright © HUAWEI Technologies Co., Ltd. 30 HUAWEI MU736 HSPA+ M.2 Module AT Command Interface Specification General Commands +CSCS: (list of supported s) OK 2.7.2 Interface Description The set command notifies TA of the TE's current character set so that TA can correctly convert TE's and MT's character sets. If TA and TE use an 8-bit interface but TE uses a 7-bit character set, the most significant bit of a character sent by the TE is set to 0. The read command queries the current TE character set. The test command queries the character set supported by the TE. 2.7.3 Parameter Description : at present, the default character set used by MS is "IRA". Other character sets are listed below (only the "IRA", "GSM" and "UCS2" character sets are supported currently). "GSM" GSM 7 bit default alphabet (3GPP TS 23.038); this setting causes easily software flow control (XON/XOFF) problems. "IRA" International reference alphabet (ITU–T T.50) (default value) "UCS2" 16-bit universal multiple-octet coded character set (ISO/IEC10646); UCS2 character strings are converted to hexadecimal numbers from 0000 to FFFF; for example, "004100620063" equals three 16-bit characters with decimal values 65, 98 and 99. Note: If MT is using GSM 7 bit default alphabet, its characters shall be padded with 8th bit (zero) before converting them to hexadecimal numbers (i.e. no SMS-style packing of 7-bit alphabet). 2.7.4 Property Description Saving upon Power-off PIN N N 2.7.5 Example Run: AT+CSCS=?
