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.

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

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.

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.

Signal Quality: +CSQ

Description: This command is used to ascertain the received signal strength indication (<rssi>) and the channel bit error rate (<ber>) with or without a SIM card inserted.

Command syntax: AT+CSQ

Command Possible responses

AT+CSQ +CSQ: <rssi>,<ber>

Note: <rssi> and <ber> as defined below

Defined values:

<rssi>:

0 13 dBm or less 1 11 dBm 2 to 30 -109 to –53 dBm 31 -51dBm or greater 99 not known or not detectable

<ber>:

0…7 as RXQUAL values in the table GSM 05.08 99 not known or not detectable

Operator Selection: +COPS

Description: There are three possible ways of selecting an operator (PLMN):

• The product is in manual mode. It then tries to find th e operator specified by the

application and if found, tries to register.

• The product is in automatic mode. It then tries to find the home operator and if found, tries to register. If not found, the product automatically searches for another network.

• The product enters into manual/automatic mode, and then tries to find an operator as specified by the application (as in manual mode). If this attempt fails, it enters automatic mode. If this is successful, the operator specified by the application is selected. The mobile equipment then enters into automatic mode.

Note: The read command returns the current mode and the currently selected ope rat o r. In manual

mode, this PLMN may not be the one set by the application (as it is in the search phase).

These commands are not allowed during communication. Command syntax: To force an attempt to select and register on a network, the application must

send the following command:

Command syntax: AT+COPS=<mode>, [<format> [ , <oper> ] ] Possible responses for AT+COPS=<mode>:

+CME ERROR: 547 Emergency call is allowed without SIM

Careful: Error code + CME ERROR: 546 or +CME ERROR: 547 are only re turned if SIM is not

present.

The fact that network supports emergency calls (+CME ERRO R: 547) does not imply

that emergency calls will work without a SIM. The only way to know it is to try atd112.

Notes: ‧ If an incoming call occurs during a PLMN list request, the operation is aborted (+CME

ERROR: 520) and the unsolicited RING appears.

‧ If SPN (Service Provider Name) is present in the SIM, it will be returned in both long

and short alphanumeric <oper> fields. The string in the “short” field will be the SPN truncated to the appropriate character number (10).

The following operations are allowed without a SIM inserted, or PIN activated: AT+COPS? : get current PLMN AT+COPS=? : List allo wed PLMN AT+COPS=1,2,<plmn> : Set manually current PLMN.

Read Operator Name: +WOPN

Description: This specific command returns the operator name in alphanumeric format, the numeric format being given. With E-ONS (Enhanced Operator Name Service) feature, <lac> is an optional parameter to read names from OPL/PNN SIM files. If it is not entered, name will be given with current <lac>. Note that in limited service, current <lac> is set to 0. You can also erase NITZ PLMN names stored in Flash memory with “AT+WOPN=3,0”. When the G2150I receives an NITZ (Network Information and Time Zone) message with Long Name or Short Name information, an entry with registered PLMN and names in message is created in flash memory. These names will then be used with +COPS,+COPN,+WOPN, +CPOL commands with the priority order defined in 3GPP TS 22.101. The G2150I supports only n etwork names with GSM default alphabet coding scheme. The user can choose which of the following methods will be used for getting PLMN names with command “AT+WOPN=4,<PlmnOns>“. The priority order is: 1 - E-ONS Firs t entry if on Home PLMN, or matching entry if existing in OPL/PNN SIM files 2 – CPHS if on Home PLMN, use SIM file CPHS ONS (0x6F14) for Long Name if present

and SIM file CPHS SONS (0x6F18) for short name if present (if not, reuse SIM

file CPHS ONS) 3 – SPN If on Home PLMN, use SIM file SPN (0x6F46) if present 4 – NITZ if there is a matching entry in the list of names received so far, use it. Note that in

France for example, all the operators use NITZ message for Date and Time feature,

but not for PLMN names, so the list is always empty. In France, an NITZ message

is sent on a GPRS attachment. FLASH If there is a matching entry in the flash PLMN list (created by +WOLM), use it. 5 - ROM PLMN names in ROM defined according to MoU SE.13 and NAPRD Operator

Names documents Once a long name is found following this priority order, it is given as a response to the AT

command. Refer to 3GPP TS 24.008, 3GPP TS 23.040, 3GPP TS 22.042 and COMMON PCN HANDSET

Enter PIN: +CPIN

Description: This command is used to enter the ME passwords (CHV1 / CHV2 / PUK1 / PUK2, etc.), that are required before any ME functionality can be used. CHV1/CHV2 is between 4 and 8 digits long, PUK1/PUK2 is only 8 digits long. If the user application tries to make an outgoing call before the SIM PIN code (CHV1) has been confirmed, then the product will refuse the “ATD” command with a “+CME ERROR: 11” (SIM PIN required). The application is responsible for checking the PIN after each reset or power on if the PIN was enabled.

Command syntax: AT+CPIN=<pin>

Command Possible responses

AT+CPIN=1234 Note: Enter PIN

AT+CPIN=5678 Note: Enter PIN

After 3 unsuccessful attempts to enter the PIN (Personal Identification Number), the PUK (Personal Unblocking Key) will be required. PUK validation forces the user to enter a new PIN code as a second parameter and this will be the new PIN code if PUK validation succeeds. CHV1 is then enabled if PUK1 is correct. The application therefore uses this command: AT+CPIN=<Puk>,<NewPin>

OK Note: PIN code is correct

+CME ERROR: 3 Note: Operation not allowed, PIN previously entered

Command Possible responses

AT+CPIN=00000000,1234 Note: Enter PUK and new PIN

AT+CPIN=12345678,1234 Note: Enter PUK and new PIN, 2nd attem p t

To ascertain which code must be entered (or not), the following query command can be used: AT+CPIN? The possible responses are:

+CPIN: READY +CPIN: SIM PIN +CPIN: SIM PUK +CPIN: SIM PIN2 +CPIN: SIM PUK2 +CPIN: PH-SIM PIN +CPIN: PH-NET PIN +CME ERROR: <err>

Please note that in this case the mobile equipment does not end its response with the OK string. The response +CME ERROR: 13 (SIM failure) is returned after 10 unsuccessful PUK attempts. The SIM card is then out of order and must be replaced by a new one. Example: 3 failed PIN validations + 1 successful PUK validation

ME is not pending for any password CHV1 is required PUK1 is required CHV2 is required PUK2 is required SIM lock (phone-to-SIM) is required Network personalization is required SIM failure (13) absent (10) etc

If the user tries to do something that requires PIN2 (CHV2), the product will refuse the action with a “+ CME ERROR: 17” (SIM PIN2 required). The product then waits for SIM PIN2 to be given. Of course, if SIM PIN2 is blocked, SIM PUK2 is required instead of SIM PIN2. For example, the product needs PIN2 to write in the fixed dialing phonebook (FDN), so if SIM PIN2 authentication has not been performed during the current session, SIM PIN2 is required.

Preferred Message Format: +CMGF

Description: The message formats supported are text mode and PDU mode. In PDU mode, a complete SMS Message including all header information is given as a binary string (in hexadecimal format). Therefore, only the following set of characters is allowed: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F}. Each pair or character is converted to a byte (e.g.: ‘41’ is converted to the ASCII character ‘A’, whose ASCII code is 0x41 or 65). In Text mode, all commands and responses are in ASCII characters. The selected format is stored in EEPROM by the +CSAS command. Command syntax: AT+CMGF=<mode>

Defined values:

<mode> PDU or text mode

0 PDU mode 1 Text mode

The <pdu> message is composed of the SC address (00 means no SC address given, use default SC address read with +CSCA command) and the TPDU message.

In this example, the length in bytes of the TPDU buffer is 14, coded as GSM 03.40

In this case the TPDU is: 0x01 0x03 0x06 0x91 0x21 0x43 0x65 0x00 0x00 0x04 0xC9 0xE9 0x34 0x0B, which means regarding GSM 03.40:

<fo> 0x01 (SMS-SUBMIT, no validity period) <mr> (TP-MR) 0x03 (Message Reference) <da> (TP-DA) 0x06 0x91 0x21 0x43 0x65 (destination address +123456) <pid> (TP-PID) 0x00 (Protocol Identifier) <dcs> (TP-DCS) 0x00 (Data Coding Scheme: 7 bits alphabet) <length> (TP-UDL) 0x04 (User Data Length, 4 characters of text) TP-UD 0xC9 0xE9 0x34 0x0B (User Data: ISSY)

TPDU in hexadecimal format must be converted into two ASCII characters. For example, the byte 0x2A is presented to the ME as two characters ‘2’ (ASCII 50) and ‘A’ (ASCII 65).

Service Center Address: +CSCA

Description: This co mmand is used to indicate to which service center the message must be sent. The product has no default value for this address. If the application tries to send a message without having indicated the service center address, an error will be generated. Therefore, the application must indicate the SC address when initializing the SMS. This address is then permanently valid. The application may change it if necessary.

Description: The +WMGO command is used to specify a location in the SIM or Flash memory, for the next SMS storing with +CMGW command. The defined location is used only once: +WMGO has to be used again to perform another overwrite.

Important notes:

y If the external application specifies a free location, and an incoming message is received

before the AT+CMGW command occurs, the product may store the incoming message at the specified available location. If the user then issues an AT+CMGW command without changing the location with another AT+WMGO, the received message will be overwritten.

Using AT Commands During a Data Connection

To use AT Commands during a data connection (e.g., while the product is in online mode), it is necessary either to switch to offline mode, or to use the specific +WMUX command to enable Commands / Data multiplexing.

Switch from online to offline mode: To switch from online mode to offline mode, the “+++” sequence must be sent. Following this, the

product gets back to offline mode with an “OK” response, and a AT command can be sent. Note: The “+++” sequence will only work with the +ICF command using one of the following

settings:

• 8 data bits, with no parity

• 7 data bits, with even parity

Switch from offline to online mode: See the ATO command description.

Bearer Type Selection: +CBST

Description: This command applies to both outgoing and incoming data calls, but in a different way. For an outgoing call, the two parameters (e.g. <speed> and <ce>) are meaningful, whereas for an incoming call, only the <ce> parameter is used. Note 1) For incoming calls, if <ce> is set to ‘T’ only and th e network offers only ‘NT’ or vice versa, then the call is released. Note 2) Values 2 and 3 for <ce> parameter are equivalent to former values 100 and 101. Those values are managed for compatibility purposes, but they shou ldn’t be used in new code (2 as former 100, and 3 as former 101).

OnCell G2150I AT Command Set V24-V25 Commands

Fixed DTE Rate: +IPR

Description: This command specifies the data rate at which the DCE will accept commands.

Notes: y The serial autobauding feature is supported, and covers the following serial speeds (only):

2400, 4800, 9600, 19200, 38400, 57600 bps. Beyond those serial speeds, proper operation of the G2150I is not guaranteed.

y Any AT command issued by the DTE must start with both capital ‘A’ and ‘T’ (or ‘/’) or

both lower case ‘a’ and ‘t’ (or ‘/’), otherwise the DCE may return some garbage characters and become desynchronized. Should this happen, the DTE simply issues ‘AT\r’ (at 2400 or 4800 bauds) once or twice or just ‘AT’ (at 9600 bauds) to resynchronize the m odem.

y The DTE waits for 1 ms after receiving the last character of the AT response (which is

always ‘\n’ or 0x0A) to send a new AT command at either the same rate or a new rate. Should this delay be ignored, the DCE can become desynchronized. Once again, sending ‘AT\r’ once or twice or just ‘AT’ causes the DCE to recover.

Caution: when starting up, if autobauding is enabled and no AT command has yet been received, the product sends all unsolicited responses (like RING) at 9600 baud.

Command syntax: AT+IPR=<rate>

Command Possible responses

AT+IPR? +IPR: 9600

Note: Current rate is 9600 bps

600, 1200, 115200) OK

Note: Possible values, according to V25ter Recommendation: the first set of values indicates the range of auto-detectable baud rates (including 0). The second set of values indicates the baud rates supported by the DCE but not auto-detectable.

AT+IPR=38400 OK

is ignored. 4: 7 Data 2 Stop (supported) <parity> parameter is ignored. 5: 7 Data 1 Parity 1 Stop (supported) if no <parity> provided, 3 is used by default as

<parity> value. 6: 7 Data 1 Stop (supported) <parity> parameter is ignored.

0: Odd (supported) 1: Even (supported) 2: Mark (supported) 3: Space (supported) 4: None (supported)

Notes:

• Setting a character framing different from 8N1 will disable autobauding if it was activated. Setting it back to 8N1 will not re-enable auto-baud.

• Setting the framing to 8N1 will let autobauding be enabled, if it was already enabled (implying framing was already 8N1).

If the DCE has never detected RTS in the high (or ON) condition since startup, then it ignores RTS (assuming this signal is not connected). As soon as the DCE detects RTS high the signal acts on it. There f ore su bs equent RTS transition to OFF will prevent the DCE from sending any further data in both online and offline modes. This behavior allows the user to use the default settings (hardware flow control) and leave RTS disconnected. In the case where RTS is connected and is high at least once, it acts on the DCE. < DTE_by_DCE >

0: none (supported) 1: Xon/Xoff circuit 104 (not supported) 2: CTS (supported)

When this parameter is set to 0 (none) then CTS is kept high all the time.

Define PDP Context: + CGDCONT

Description: This Command specifies PDP context parameter values for a PDP context identified by the local context identification parameter, <cid>. Four PDP contexts can be defined through MOXA software. A special form of the set command, +CGDCONT= <cid> causes the values for context number <cid> to become undefined. The test command returns values supported as a compound value. If the MT supports several PDP types, <PDP_type>, the parameter value ranges for each <PDP_type> are returned on a separate line. The read command returns the current settings for each defined context. The test command returns values supported as a compound value. If the MT supports several PDP types, <PDP_type), the parameter value ranges for each <PDP_type> are returned on a separate line.

definition. The parameter is local to the TE-MT interface and is used in other PDP context-related commands. Range of values is 1 to 4.

<PDP_type>: (Packet Data Protocol type) a string parameter which specifies the type of packet data protocol

• IP: Internet Protocol

• PPP: Point to Point Protocol <APN>: (Access Point Name) a string parameter, which is a logical name that is used to select the GGSN or the external packet data network.

OnCell G2150I AT Command Set GPRS Commands

<PDP_address>: a string parameter that identifies the MT in the address space applicable to the PDP. If the value is null or omitted, then a value may be provided by the TE during the PDP startup procedure, or a dynamic address will be requested. The read form of the command will return the null string even if an address has been allocated during the PDP startup procedure. The allocated address may be read using the +CGPADDR command. <d_comp> a numeric parameter that controls PDP data compression ‧ 0: OFF (default if value is omitted)

‧ 1: ON ‧ Other values are reserved. <h_comp> a numeric parameter that controls PDP header compression

‧ 0: OFF (default if value is omitted) ‧ 1: ON ‧ Other values are reserved.

Notes: ‧ The data compression algorithm provided in SNDCP is V.42bis.

‧ 4 CIDs are available to specify 4 PDP context but only 11 NSAPI are available for

PDP activation. 4 PDP contexts can be specified with only one activated at the same time.

Quality of Service Profile (Requested): +CGQREQ

Description: This command allows the TE to specify a Quality of Service Profile that is used when the MT sends an Activate PDP Context Request message to the network. The set command specifies a profile for the context identified by the local context identification parameter, <cid>. Since this is the same parameter that is used in the +CGDCONT command, the +CGQREQ command is effectively an extension to the +CGDCONT command. The QoS profile consists of a number of parameters, each of which may be set to a separate value. A special form of the set command, +CGQREQ= <cid> causes the requested profile for context number <cid> to become undefined. The read command returns the current settings for each defined context. The test command returns values supported as a compound value. If th e MT supports several PDP types, the parameter value ranges for each PDP type are returned on a separate line.

Quality of Service Profile (Minimum acceptable): +CGQMIN

Description: This command allows the TE to specify a minimum acceptable profile that is checked by the MT against the negotiated profile returned in the Activate PDP Context Accept message. The set command specifies a profile for the context identified by the local context identification parameter, <cid>. Since this is the same parameter that is used in the +CGDCONT command, the +CGQMIN command is an extension to the +CGDCONT command. The QoS profile consists of a number of parameters, each of which may be set to a separate value. A special form of the set command, +CGQMIN= <cid> causes the minimum acceptable profile for context number <cid> to become undefined. In this case, no check is made against the negotiated profile. The read command returns the current settings for each defined context. The test command returns values supported as a compound value. If the MT supports several PDP types, the parameter value ranges for each PDP type are returned on a separate line.

If a value is omitted for a particular class then this class is not checked.

GPRS Attach or Detach: +CGATT

Description: The execution command is used to attach the MT to, or detach the MT from the GPRS service. After the command has completed, the MT remains in V.25ter command state. If the MT is already in the requested state, the command is ignored and the OK is returned. If the requested state cannot be achieved because the GPRS is not supported by the MT, an ERROR or +CME ERROR response is returned. Extended error responses are enabled by the +CMEE command. Any active PDP contexts will be automatically deactivated when the attachment state changes to detached. The read command returns the current GPRS service state. The test command is used for requesting information on the supported GPRS service states..

• 0: detached

• 1: attached

• 2: combined detach (GPRS and GSM detach in the same network request)

• Other values are reserved and will result in an ERROR response to the execution command.

PDP Context Activate or Deactivate: +CGACT

Description: The execution command is used to activate or deactivate the specified PDP context(s). After the command has completed, the MT remains in V.25ter command state. If any PDP context is already in the requested state, the state for that context remains unchanged. If the requested state for any specified context cannot be achieved, an ERROR or +CME ERROR response is returned . Extended error responses are enabled by the +CMEE command. If the MT is not GPRS attached when the activation form of the command is executed, the MT first performs a GPRS attach and then attempts to activate the specified contexts. If the attach fails then the MT responds with ERROR, or if extended error responses are enabled, with the appropriate failure-to-attach error message. If no <cid>s are specified the activation form of the command activates the first possible within the defined contexts. If no <cid>s is specified the deactivation form of the command deactivates all active contexts. One PDP contexts can be activated through MOXA software at the same time. The read command returns the current activation states for all the defined PDP contexts. The test command is used for requesting information on the supported PDP context activation states.

<cid>: a numeric parameter that specifies a particular PDP context. Before the activation of the

context, the MT has to attach itself to the GPRS network if necessary.

Note: if a GPRS PPP session is already running, the setting of a CSD (GSM data call) is not

supported.

OnCell G2150I AT Command Set GPRS Commands

Enter Data State: +CGDATA

Description: This command causes the MT to perform the necessary actions to set up communication between the TE and the network. This may include performing a GPRS attach and one PDP context activation. If the <cid> value is not defined to the MT, it will return an ERROR or +CME ERROR response. Otherwise, the MT issues the intermediate result code CONNECT and enters V.25ter online data state. GPRS attachment and PDP context activation procedures may take place prior to or during the PDP startup if they have not already been performed using the +CGATT and +CGACT commands. If no <cid> is given, the MT attempts to activate the context with available information. The other context parameters are set to their default values (No APN, default QOS parameters, dynamic IP address requested). If the activation is successful, data transfer may proceed. After data transfer and layer 2 protocol termination procedure completion, the V.25ter command state is re-entered and the MT returns the final result code OK. In case of abnormal termination or start up, the V.25ter command state is re-entered and the MT returns the final result code NO CARRIER or, if enabled, +CME ERROR. Attach, activate, and other errors may be reported. This command may be used in both normal and modem compatibility modes.

Notes:

y This command has the same effects than ATD*99***. y If a GPRS PPP session is already running, the setting of a CSD (GSM data call) is not

supported.
