1 Scope

This document describes the AT interface of Huawei UMTS Module. The description on the AT interface is only limited to the interface packet itself, the usage and use procedure of TE and MS, and does not cover the contents which are not directly related to the interface.

Note: Reinforced insulation or double insulation must be provided to isolate DC source from AC mains supply.

HUAWEI UMTS Module is a wireless terminal of UART or USB interface. It is used to provide data service, voice and SMS functions.

This document describes the AT interface. Therewith no description or definition explain for the document interface, and no temporary support to all kinds of parameter values, so no suggestion of usage.

In the subsequent AT command parameters, two formats are involved: <>, and [], as described below:

<...> Parameters enclosed in angle brackets must be completed. Brackets

[...] Optional subparameter of a command is enclosed in square brackets.

<CR> Carriage return character, which value is specified with command S3. <LF> Linefeed character, which value is specified with command S4.

1.2 Interface Design Principles

1) Each interface should be functionally convergent.

2) Since the AT command is a packet transmitted via communication port, the packet size is limited. For the transmission of AT command, in addition to the two characters “AT”, a maximum of 1600 characters can be received (including the

empty characters

HUAWEI UMTS M2M Module AT Command Interface Specification Confidential

at the end). For the “response” message or URC reported by the board, the maximum length is limited to 1600 characters.

3) Each command line can include only one AT command. For the URC instruction or response reported from MS to TE, only one AT command is allowed in a command line.

4) In order to make the commands and response formats more readable and standard, except the original interfaces of Qualcomm, in all newly added interfaces, e.g. no space can be contained in the commands such as AT%XXX: <arg0>, <arg1>, or behind %, colon or comma. No redundant space is allowed at the head or end.

5) After delivering each AT command, the TE cannot deliver the second AT command until the MS has made response to this AT command. Otherwise, the second AT command will not be executed.

6) 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 MS responds to the TE only after a long time of waiting, e.g. the “AT+CCFC=?” command receives a response only after a long time after the command is delivered, the MS may have received the reported instruction of RING on this occasion. Namely, the reporting of RING may interrupt other responses, and other URCs will not interrupt the response of command, and the interrupted part of the response will continue being reported.

7) Unless otherwise specified, all default codes between TE and MS take on this format: GSM 7 bit Default Alphabet. See also Section 6 in protocol 23.038. The character @ is transmitted on the interface still according to 0x00 of 7bit coding. The board software and API should be able to process this character. The board uploads the carriage return character (<CR>) and linefeed character (<LF>) in the string in the form of space.

8) a sort of compounding between quotation and comma can not exist in the string in this current version. For the data format of UCS2 code, the code value should be reported in the string format (if the code value is 0x553a, 553a should be reported).

9) The “Possible response” sent from MS to TE is composed of “Information text” and “Result code”, where “Information text” is optional, and “Result code” is mandatory. The format of “Possible response” is controlled by the ATV command, as detailed in the ATV command description. All “Possible responses” listed in the tables in this documents are in the ATV1 format.

1.3 Interface Change Principles

For the extended interface, parameters can be added behind the AT command. If the interface fails to meet the new requirements as detected in the later stage of product development, new parameters can be added on the basis of the original interface. In addition, for all the currently available interfaces, if the command received by MS is not identifiable, the “result code” of COMMAND NOT SUPPORT will be reported; if there is one surplus command parameter, the MS will report the “result code” of the corresponding TOO MANY PARAMETERS. No equal mark itself is deemed a surplus command parameter.

All newly added AT command interfaces of the E630 project team begin with “%”. This project team specifies that: In the AT command name such as “AT%XXX”, the number of X cannot be more than 9 currently.

2 Interface Introduction

HUAWEI UMTS M2M Module AT Command Interface Specification Confidential

All interfaces herein refer to the interfaces between TE and MS, and are used for guiding the implementation of the function requirements. The interface covers voice call, short message receiving and sending, data traffic flow, phone book statistics, supplementary service, and MS network system information setting.

For the commands sent from TE to MS, see also the detailed description in Appendix

16.1. Note that in the returned results of the TEST command, “,” and “-” are different. For example, the returned result of “+CMGD=?” is: +CMGD: (1,5),(0-4), which means that the first parameter value may be 1 or 5, and the second parameter value may range from 0 to 4.

This command is used to set whether to use result code: +CME ERROR:<err> indicates the error related to MS. When you set to use result code, the MS-related error will generate a result code: +CME ERROR: <err>, which will replace the ordinary ERROR result code. If the error reasons are not related to MS, the ordinary ERROR will still be returned.

3.1.3 Defined Values

<n>: 0 Do not use +CME ERROR :<err>result code, only ERROR is returned in case of

error occurrence. 1 Use +CME ERROR :<err>result code, <err> adopts the error code value. 2 Use +CME ERROR :<err>result code, <err> adopts the detailed string value of

the error. <err>: The value is given in the CME ERROR list in the Appendix.
