OnCell G2150I AT Command Set Introduction

Definitions

The words “Mobile Station” (MS) or “Mobile Equipment” (ME) are used for mobile terminals that support GSM services. Terminal Equipment (TE) is the Human Machine Interface (HMI) of a GSM device (modem or handset). TE can be a handset HMI or the AT command line interface.

OnCell G2150I

User GSM network

A call from a GSM mobile station to the PSTN is called a “mobile originated call” (MOC) or “outgoing call,” and a call from a fixed network to a GSM mobile station is called a “mobile terminated call” (MTC) or “incoming call.”

Presentation Rules

In the remainder of this document, AT commands are presented in three parts. A “Description” paragraph provides general information about the AT command (or response) behavior. A “Syntax” paragraph describes how to use the command, and gi ves possible responses in a readable format. A “Defined values” paragraph provides parameter values, and the AT command for the corresponding responses. Schemas are provided where necessary.

OnCell G2150I AT Command Set AT Command Features

Serial Line Settings

A serial link handler is configured with the following default values (factory settings):

y 115200 bps y 8 data bits y 1 stop bit y no parity y RTS/CTS flow control

Use the +IPR, +IFC, and +ICF commands to change these settings.

Command Line

Commands always start with AT (which means ATtention) and finish with a <CR> character.

Information Response and Result Codes

Responses start and end with <CR><LF> (except for the ATV0 DCE response format) and the ATQ1 (result code suppression) commands.

y If the command syntax is incorrect, the “ERROR” string is returned. y If the command syntax is correct, but the command is transmitted with the wrong parameters,

the +CME ERROR: <Err> or +CMS ERROR: <SmsErr> strings are returned with adequate error codes if CMEE was previously set to 1. By default, CMEE is set to 0, and the error message is only “ERROR.”

y If the command line has been executed successfully, an “OK” string is returned. In some cases, such as “AT+CPIN?” or (unsolicited) incoming events, the product does not return

the “OK” string as a response. In the following examples <CR> and <CR><LF> are omitted intentionally.

Note: Supports GSM and FAX commands

Defined values: No parameter

Power Off: +CPOF

Description: This specific command stops the GSM software stack as well as the hardware layer, or the G2150I activity. The AT+CFUN=0 command is equivalent to +CPOF.

Command syntax: Command syntax: AT+CPOF[=1]

Command Possible responses

AT+CPOF

Note: Stop GSM stack

AT+CPOF=1 Note: Stop the Wireless CPU

Note: After AT+CPOF=1, the G2150I will not respond to AT commands. To reset it, use the hard reset. Note: In autobaud mode, after an AT+CPOF, unsolicited information waking up the G2150I is sent at 9600 bps until an AT command is sent. When an AT command is sent, the G2150I will synchronize with the sender’s speed. (see CAUTION in § 14.1.1) Defined values: No parameter

Set Phone Functionality: +CFUN

Description: This command selects the mobile station’s level of functionality. When the application wants to stop the product with a power off, or if the application wants to force the product to execute an IMSI DETACH procedure, then it must send: AT+CFUN=0 (equivalent to

OK Note: Command valid

3-5

OnCell G2150I AT Command Set General Commands

AT+CPOF). This comma nd executes an IMSI DETACH and makes a backup copy of some internal parameters in SIM and in EEPROM. The SIM card cannot then be accessed. If the mobile equipment is not powered off by the application after this command has been sent, a re-start command (AT+CFUN=1) will have to issued to restart the whole GSM registration process. If the mobile equipment is turned off after this command, then a power on will automatically restart the whole GSM process. The AT+CFUN=1 command restarts the entire GSM stack and GSM functionality: a complete software reset is performed. All parameters are reset to their previous values if AT&W was not used. If you write entries in the phonebook (+CPBW) and then reset the product directly (AT+CFUN=1, with no previous AT+CFUN=0 command), some entries may not be written (the SIM task does not have enough time to write entries in the SIM card). In addition, the OK response will be sent at the last saved (AT&W) baud rate defined by the +IPR command. With the autobauding mode the response can be at a different baud rate. It is therefore preferable to save the defined baud rate with AT&W before directly sending the AT+CFUN=1 command.

Command syntax: AT+CFUN=<functionality level>

Command Possible responses

AT+CFUN?

Note: Ask for current functionality level

AT+CFUN=0

Note: Set minimum functionality, IMSI detach procedure

AT+CFUN=1

Note: Set the full functionality mode with a complete software reset

+CFUN: 1 OK

Note: Full functionality

Note: Command valid

Defined values: <functionality level> 0: Set minimum functionality, IMSI detach procedure 1: Set the full functionality mode with a complete software reset

Phone Activity Status: +CPAS

Description: This command returns the activity status of the mobile equipment. Command syntax: AT+CPAS

Command Possible responses

AT+CPAS

Note: Current activity status

Defined values: <pas> 0 ready (allow commands from TA/TE) 1 unavailable (does not allow comma nds) 2 unknown 3 ringing (ringer is active) 4 call in progress 5 asleep (low functionality)

+CPAS: <pas> OK

3-6

OnCell G2150I AT Command Set General Commands

Report Mobile Equipment Errors: +CMEE

Description: This command disables or enables the use of the “+CME ERROR: <xxx>“ or “+CMS ERROR:<xxx>“ result code instead of simply “ERROR”.

Command syntax: Command syntax: AT+CMEE=<error reporti n g fl ag>

Command Possible responses

AT+CMEE=?

AT+CMEE=0 Note: Disable ME error r eports, use only “ERROR ”

AT+CMEE=1

Note: Enable “+CME ERROR: <xxx>“ or “+CMS ERROR: <xxx>“

Defined values: <error reporting flag> 0: Disable ME error reports, use only « ERROR » 1: Enable «+CME ERROR: <xxx>» or «+CMS ERROR: <xxx>»

+CMEE: (0,1) OK

Keypad Control: +CKPD

Description: This command emulates the ME keypad by sending each keystroke as a character in a <keys> string. The supported GSM sequences are listed in the appendix. If emulation fails, a +CME ERROR: <err> is returned. If emulation succeeds, the result depends on the GSM sequence activated: Note: In the case where the FDN phonebook is activated, the sequences concerning “call forwarding” are allowed only if the entire sequence is written in the FDN.

Command syntax: AT+CKPD=<keys>

Command Possible responses

AT+CKPD=“*#21#”

Generic SIM Access: +CSIM

Description: This command allows direct control of the SIM by a distant application on the TE. The <command> is sent without any modification to the SIM. In the same manner the SIM <response> is sent back by the ME as it is. The user shall then take care of processing SIM

information within the frame specified by GSM as specified in GSM 11.11(or 3GPP TS

51.011). If operation mode is not allowed by the ME, +CME ERROR: <error> is returned.

Between two successive +CSIM commands, there is no locking of the interface between the SIM and the GSM application. Since in this situation some command types and parameters can modify the wrong SIM files, some operations, described below, are not allowed for CSIM command. However, it is possible to process them with the CRSM command.

For command sent to TE, This value must be in the range [10 – 522], or a CME_ERROR=3 is returned. <command>: hexadecimal type Command passed on by the MT to the SIM in the format as described in GSM 11.11 (or 3GPP TS

51.011) (hexadecimal character format; refer +CSCS) Second Byte Value not supported:

Due to the absence of locking, a CME_ERROR=3 is returned for the following instructions ( See CRSM commands):

• A2: SEEK the user must make sure that the value of the fifth Byte of the instruction corresponds to the length of bytes (data starting from 6th byte) which follow it. The value of the Fifth Byte must be equal of the value: <length>/2 – 5, or the command

is not sent to the SIM and CME_ERROR=3 is returned. <error>: integer type 3: Wrong format or parameters of the command 13: SIM no response <response>: hexadecimal type

Response to the command passed on by the SIM to the MT in the format as described in

GSM 11.11 (or 3GPP TS 51.011) (hexadecimal character format; refer +CSCS)

Restricted SIM Access: +CRSM

Description: By using this command instead of Generic SIM Access the +CSIM TE application gives easier but more limited access to the SIM database. This command transmits to the MT the SIM <command> and its required parameters. As a response to the command, MT sends the actual SIM information parameters and response data. MT error result code +CME ERROR may be returned when the command cannot be passed to the SIM, but failure in the execution of the command in the SIM is reported in <sw1> and <sw2> parameters. As for the CSIM command, there is no locking between two successive commands. The user should be aware of the precedence of the GSM application commands to the TE commands.

Multiplexing Mode: +CMUX

Description: This command is used to manage (enable or disable) the 3GPP TS 27.010 multiplexing protocol control channel. This command allows the multiplexing of 4 logical channels on a single UART. Two

UARTs are available on the G2150I, but multiplexing can only apply to one. The client

application may handle, by this means, up to 5 channels (4 logical multiplexed channels

on a UART and 1 physical channel on the other UART). Notes on speed and autobauding:

• The speed of the response is the same that the one of the received AT+CMUX

command (prior to entering <mode>).

• It is recommended that, whenever the multiplexer control channel is released, the

modem should assume an interface rate for autobauding purposes, irrespective of any

previous higher speed selected.

•If a +CMUX command is issued while in any multiplexer mode, then that +CMUX

3-12

OnCell G2150I AT Command Set General Commands

command is ignored and the modem will return a +CME ERROR: <err> response. Restrictions

• Only basic option and UIH framing is supported.

• Only convergence layers type 1 and 3 are supported.

• Autobauding is not compliant with multiplexing mode. It is neither possible to start

multiplexing when autobauding is active (AT+IPR=0), nor to set autobauding during

multiplexing mode, since the multiplexer uses only a fixed baudrate. In the same way,

the bit rate cannot be changed through the AT+IPR command while multiplexing mode

is active. Therefore, the AT+IPR=<rate> command should not be used and will have no

effect.

• Before starting multiplexing mode, port speed must be configured by the

AT+IPR=<rate> command, to be compliant with values defined in 4.24.3 Defined

valuesfor <port_speed> parameter. Specific behaviors

• In multiplexing mode, AT configuration commands (AT+CMEE for example), will be

applied to all logical channels.

• In multiplexing mode, unsolicited result code will be sen t to all logical channels.

• Since AT commands are grouped by classes, launching an AT command from a port

causes the lock of all commands belonging to the same class. If an AT command of the

locked class is launched from another port, a +CME ERROR: 536 will occur as long as

the class is not released (at first command completion time).

• In internal mode, if GPS is used on UART2, it is not po ssible to start multiplexing

mode on UART2. In the same way, if multiplexing mode is started on UART2, it is not

possible to use GPS in internal mode.

• If Bluetooth is started, it is not possible to start multiplexing mode on UART2. In the

same way, if multiplexing mode is started on UART2, it is not possible to start

Bluetooth.

• If TMT (Terminal Emulator) is launched on a specific UART, it is not possible to start

multiplexing mode on this UART. TMT must be closed before starting multiplexing

mode. On the other hand, as soon as multiplexing mode is started, HAPC can be started

on a DLCi.

• After an AT+CFUN=1 command during a multiplexing mode session, multiplexing

mode is automatically restarted by the modem with previous parameters and all

previous opened DLCs are reopened with the speed of AT+IPR? Command.

• DCD, RI, and DTR signals are managed virtually; when V24 sets DCD, RI or DTR

signals, an MSC frame is sent to the remote part to indicate a virtual state change. All is

logical, no physical signal is involved.

• +++ Escape Sequence is always available to get offline.

• Flow control can be managed either physically, or virtually by MSC. By default, the

G2150I manages hardware flow control on a UART, which becomes virtual on logical

channels when some DLCs are opened.

• At multiplexing mode session stop, it is not necessary to reset the G2150I; it

automatically goes back into AT mode.

• 2 timeouts are implemented for multiplexing mode connection: y Multiplexing mode starts the connection: 30 seconds. After this timeout, multiplexing mode is

stopped and a previous physical port is reopened.

y DLC inactivity timeout: 5 minutes This timeout is armed only if no DLC is opened, to avo id to

be blocked into only DLC0 opening channel state. After this timeout, multiplexing mode stopped and previous physical port is reopened.

Dial Command: D

Description: The ATD command is used to set a voice, data or fax call. As per GSM 02.30, the dial command also controls supplementary services.

For a data or a fax call, the application sends the following ASCII string to the product

(the bearer must be previously selected with the +CBST command):

ATD<nb>

Note: If a GPRS PPP session is already running, the setting of a CSD (GSM data

call) is not supported.

For a voice call, the application sends the following ASCII string to the product: (the

bearer may be selected previously; if not, a default bearer is used). ATD<nb>; where <nb> is the destination phone number. Emergency calls The following Emergency Numbers are available without a SIM card:

000, 08, 110, 112, 118, 119, 911 and 999. The following Emergency Numbers are available with a SIM card:

when EF_ECC file is missing from SIM: 112 and 911 when SIM includes an EF_ECC file: 112, 911 and any Emergency Numbers

available in the EF_ECC file. Please note that for an international number, the local international prefix does not need to be

set (usually 00) but does need to be replaced by the ‘+’ character. Example: to set up a voice call to MOXA offices from another country, the AT command is:

“ATD+886289191230;” Note that some countries may have specific numbering rules for their GSM handset

numbering.

The response to the ATD command is one of the following:

Verbose result code Numeric code

(with ATVO set)

OK 0 If the call succeeds, for voice call only CONNECT <speed> 10, 11, 12, 13, 14, 15 If the call succeeds, for data calls only,

BUSY 7 If the called party is already in communication NO ANSWER 8 If no hang up is detected after a fixed network

NO ANSWER 3 Call setup failed or remote user release. Use

Direct dialing from a phonebook (stored in the SIM card) can be performed with the following command:

ATD> <index>; to call <index> from the selected phonebook (by the +CPBS

command) ATD> “BILL”; to call “BILL” from the selected phonebook ATD> mem <index> (mem is “SM”,”LD”,”MC”,”ON”,”ME”,”RC”,”MT” or “SN”, See +CPBS command) allows direct dialing from a phonebook number..

Note: Call index 6 from ADN phonebook

When the FDN phonebook has been locked, only numbers beginning with the digits of FDN

phonebook entries can be called. For example, if “014629” is entered in the FDN phonebook all the phone numbers beginning with these 6 digits can be called. The CLIR

supplementary service subscription can be overridden for this call only. “I” means “invocation” (restrict CLI presentation). “i” means “suppression” (allow CLI presentation). Control of CUG supplementary service information by “G” or “g” is allowed for this

call only. The index and info values set with the +CCUG command are used. An

outgoing call attempt could be refused if the AOC service is active and credit has

expired (NO CARRIER). When trying to set up an outgoing call while there is an active

call, the active call is first put on hold, then the call set up is carried out. As per GSM

02.30, GSM sequences may be controlled using dial commands. These sequences can

contain “*”, “#”, but “;” is forbidden. If the sequence is not supported or fails, +CME

ERROR: <err> is returned. In the case where the FDN phonebook is activated, the

sequence concerning call forwarding are allowed only if there are written in the FDN.
