HUAWEI MC509 CDMA LGA Module

AT Command Interface Specification

Overall Description

This chapter briefly describes the contents and organization of this document and

focuses on the basic knowledge of AT command interfaces.

1.1 Content Description

This document describes the AT command interface specification that is supported by

Huawei terminal product MC509 module. This document describes certain AT

commands (implemented by terminal devices) of international standards such as

TIA/EIA/IS-707-A.3,GSM 07.07, GSM 07.05, and International Telecommunication

Union-Telecommunication Standardization Sector (ITU-T) V.250 [14] according to the

requirements of terminal devices. In addition, this document describes the proprietary

AT command interfaces that are implemented by terminal devices.

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 MC509. The

description of AT command interfaces covers only the data packets of interfaces and

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 interworking

function (IWF).

1.2 Product Description

HUAWEI MC509 (the MC509) is a CDMA LGA module product, supporting two

CDMA frequency bands, that is, CDMA800 and CDMA1900.

The MC509 provides one external UART interface and supports functions such as

short message service (SMS), phone book, data service, and embedded TCP/UDP.

AT Command Interface Specification

Overall Description

1.3 Instructions for Use

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:

<...>

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.

<CR> Carriage return character. For details, see the description in S3.

<LF>

Line feed character. For details, see the description in S4.

When an AT command is sent, the characters contained in the name and parameters

(excluding SMSs, phone book, and operator name) of the AT command are case

insensitive. All the characters contained in the result returned by the AT command

must be in upper case (excluding SMSs, phone book, operator name and error

messages).

When an AT command is sent, string parameters can be placed inside quotation

marks or not.

1.4 Overview of AT Command Interfaces

1.4.1 Description of AT Commands

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.

1.4.2 Types of AT Commands

AT commands are categorized into three types: basic commands, S register

commands, and extended and vendor-defined commands.

A basic command starts with a single letter or with the & symbol plus a single letter.

T a ble 1-1 describes the format of a basic command.

Overall Description

Table 1-1 Format of a basic command

Command Format

Description

<command>[<number>] In the command format, <command> indicates a single

letter (A–Z) or the & symbol plus a single letter.

In the command format, <number> indicates a decimal

number with one digit or multiple digits. The digit 0 at

the start of <number> can be ignored.

Note:



If a basic command that is allowed to contain <number> does not contain <number>, the

default value of <number> is used in the command.



If a basic command that is not allowed to contain <number> contains <number>, "ERROR"

or “+CME ERROR : operation not allowed” is returned.

An S register command consists of the letter S and a decimal number, which is called

the parameter number of the register. An S register command can be in the format of

read command and set command. T a ble 1-2 describes the format of an S register

command.

Table 1-2 Format of an S register command

Command Format

Description

Read

S<parameter

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.

command number>?

Set

S<parameter

Replaces the characters saved in the S register

command number>=<value> with the characters related to the value of

<value>.

Note:

If the parameter number of the register is not identified, this indicates that the command does

not exist. In this case, ERROR is returned.

All extended commands start with the + symbol. Vendor-defined commands start with

a special symbol such as ^ and %. In this document, all vendor-defined commands

start with the ^ symbol. Extended and vendor-defined commands are further

categorized into action commands and parameter commands. T a ble 1-3 describes

the types and formats of extended and vendor-defined commands.

An action command refers to a command that performs a specific action in addition

to interacting with the local parameters of the MS, including AT+CPBR and

AT^HCMGS. An action command may or may not contain parameters. Action

commands are categorized into execution (write) command and test command. A

parameter command refers to a command that interacts with the local parameters of

the MT only, certain of which may affect the execution of action commands.

Parameter commands are categorized into set command, read command, and test

command.

1.4.3 Abort Attributes of AT Commands

Abort means that the TE sends an instruction to abort a command when the

command is being executed. An abort instruction must be sent before a command is

completely executed. Therefore, the abort instruction is valid for a command whose

execution consumes certain time; however, not all commands of this kind can be

aborted. Whether a command can be aborted depends on the abort attribute of the

command. Each AT command has its abort attribute, which is alternative. That is, the

command is either abortive or not abortive. Abortive commands include certain basic

commands and execution commands of action commands. Within 125 ms after the

abortive commands are sent, no abort request is accepted. After 125 ms and before

the commands are completely executed, if the module receives any character sent

by the TE, the commands are aborted immediately.

1.4.4 Rules for Running AT Commands

1. Each command line contains only one AT command and ends with a carriage

return character, in addition to the basic standard commands such as 1, V, S3

etc. 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.

2. To increase the readability and regularity of command and response formats, in

addition to the original interfaces specified in standards and protocols, all new

interfaces must observe the following rule: No space is added to the end of

commands such as the AT^XXX=<arg0>,<arg1> commands, or added to the

end of the ^ symbol, colon, and comma. No redundant space is added ahead of

Overall Description

or to the end of a command. This rule is applicable to the communication

between the MT and TE programs.

3. For an uninterruptible AT command, after sending the AT command, the TE

must wait until the MT responds to the AT command before sending the second

AT command.

4. A string used by the TE to send a command cannot contain the combination of

quotation marks and commas (confusing a parameter with a string). The current

version does not support escape character. The code value of a data format in

the UCS2 encoding is reported as characters. For example, if the UCS2 code of

a Chinese character is 0x553a, the 553a is reported.

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.

8.2.2 Interface Description

The set command sets the mode of notifying the TE of a new short message. Where:

<mode> and <bfr> are used to set the mode of notifying the TE of a new short

message.

<mt> sets the storage and notification rules for newly received short messages: a

new short message is directly reported to the TE; or a new short message is stored in

the MT and the storage position is reported to the TE.

<ds> sets whether a short message status report (+CDSI, ^HCDS) is sent.

The supported parameter value is returned when the test command is executed.

8.2.3 Parameter Description

<mode>: Specifies the short message notification mode.

0: The short message notification is stored in the buffer of the MT. If the buffer of the

MT is full, the new notification overwrites the oldest notification.

1: The short message notification is sent to the TE. If the short message notification

fails to be sent (for example, in online data mode), the notification is discarded

(default value after startup).

2: Send a message notification and message status report to the TE. If the sending

fails (for example, in the online data mode), buffer the message notification in the MS

and send it to the TE later.

In CDMA mode, <mode> always set to 1.

<mt>: Specifies the storage and notification rules for received short messages.

The storage and notification for a new short message has the two modes:

1. The short message is stored in the MT, and a storage position notification is sent to

the TE (default value after startup).

The short message notification uses the +CMTI command, that is, a new short

message is stored in <mem3> specified by the +CPMS command; the storage

location and the index value are reported to the TE.

2. The short message is not stored in the MT but is directly sent to the TE.

The short message notification uses the ^HCMT command. A new short message is

not stored on the board. It is reported to the TE. The TE needs to call the AT+CNMA

command to acknowledge the reported short message. If the AT+CNMA command is

not received within two seconds, the MT sends a receiving error to the network.

This command replies to the ^HCMT or ^HCDS indication received by the TE from

the MT.

The execution command acknowledges the reception of a new short message sent

to the TE. For usage of the command, see the +CNMI command.

Before the previous received short message is acknowledged, the MT does not send

another ^HCMT or ^HCDS command to the TE.

If the MT does not obtain a short message acknowledgement in the specified time

(about two seconds) (due to network timeout), it sends "RP-ERROR" to the network.

If this command is executed but no short message needs to be acknowledged,

"+CMS ERROR:<err>" is returned.

TE wait for <CR><LF><greater_than><space>(IRA 13, 10, 62, 32) from the MT，

and input the message content that end with<ctrl-Z> (IRA 26).

TEXT mode:

The ^HCMGS=<da>[,<toda>] command is sent with the end of (CR).

The TE waits <CR><LF><greater_than><space>(IRA 13, 10, 62, 32) returned by

the MT, and then sends the message content ending with <ctrl-Z> (IRA 26).

In TEXT mode, it only supports 0~0x00FF with UCS2.

The maximum length of message is 160 characters with 7bit codec, and 70

characters with UCS2S.

8.9.3 Parameter Description

<length>: the length is bytes of layer3 packet.

<da>: Specifies the number of the recipient of a short message. It is a string with

double quotation marks, consisting of a maximum of 20 characters. The value can be

0–9, *, #, and +. The "+" symbol can only be at the start of the number.

<toda>: Specifies the address encoding format. It is a digit of one byte. It is not

supported at present. The default value is 0.

<mr>: A decimal digit, specifying the identifier of a short message. The value ranges

from 0 to 65535.

<ctrl-Z>: Identifies the end of a short message. The character is '0x1A' ('0x001A' in

the Unicode).

<ESC>: Indicates that the sending of a short message is canceled. The character is

'0x1B' ('0x001B' under the Unicode).

<Layer3 packet>：the character is 0～9、A～F，two characters form a Octet.

Sending of a short message adopts the asynchronous command processing mode in the AT

command. Currently, the asynchronous command processing process cannot process other

AT commands. During the process, if the MT receives a short message-related command,

such as the +CPMS, ^HCMGR, +CMGD, ^HCMGL, +CNMA, +CNMI, or ^HCMGW command,

it returns "+CMS ERROR:302". That is, the operation is not allowed. If the MT receives the

^HCMGS command, it returns "^HCMGSF: 0". If the MT receives another command unrelated

to a short message, it returns "+CME ERROR:40". That is, the operation is not allowed.



2: speed optimal, mobile tries to obtain position fixes in such a way that TTF is

minimal, depending upon the fix rate and initial uncertainties, MS decides

whether to attempt MS-based fix or MS-assisted fix。In CDMA, MS-based and

download ephemeris from AGPS server is preferred, if failed then MS-assisted.

In UMTS, it‟s just MS-based.



3: accuracy optimal, mobiles tries to obtain position fixes with best accuracy. In

CDMA, MS-Assisted mode and download ephemeris from AGPS server is

preferred, MS-based mode uses only if MS-assisted fix fails. In UMTS, it‟s just

MS-assisted.

4: data optimal, MS will try to minimize the amount of data exchanged over the

network. In CDMA, MS-based and download ephemeris from AGPS server is a

preferred mode over MS-assisted mode, and minimum AGPS server/network

access is allowed. In UMTS, it‟s just standalone.



5: MS-based only, all position fixes provided to PD client are calculated by MS. If

communication with network fails, the session will fallback to standalone.

6: gpsOneXTRA, provide enhanced standalone performance。It eliminates the

need to demodulate the GPS signal for ephemeris, almanac, iono, UTC, or

health.



7: Cell-ID, the user position will be fixed by the cell which the MS in.

15.1 CME ERROR List

For all AT commands, if the default value of the CMEE is 2, "ERROR" can be reported, or

"CME ERROR" can be reported. "CME ERROR" includes certain common errors ad certain

specific errors of the AT commands.

T a ble 15-1 lists CME ERRORs that may be produced by certain interface commands

and causes. The numbers in the header row are the <err> values of the CME

ERROR, and numbers in the body of the table are cause IDs. For the mapping

between the <err> value of CME ERROR and the string, see T a ble 15-2 . The

causes are described later.

For example, 7 is entered in the column of the +CPWD= command row with the

<err> value of 16, which indicates that the +CPWD= command may produce CME

ERROR with the <err> value of 16. The text string is "incorrect password", the cause

ID is 7, and the specific cause explanation is "incorrect password".
