2. PRELIMINARY INFORMATION

Before describing the AT commands use, it is needed to define a way to point out significant differences, when needed, between modules belonging to different series, or having different software versions.

In 2G Modules sub-chapters (or under label in the text) are described AT commands examples concerning the modules supporting the 2G Technology only. Where needed, the guide specifies also the software version.

In 3G Modules sub-chapters (or under label in the text) are described AT commands examples concerning the modules supporting the 2G/3G Technologies. Where needed, the guide specifies also the software version.

If the AT command example is valid for all products, no labels or dedicated chapters are used.

Chapter 1.29 is focusing on the Default/Dedicated EPS Bearer (4G modules)

The AT commands use specified in this guide assumes that the #SELINT=2 AT

Interface Style is used.

Refer to document [1]/[17]/[26] in accordance with the module that you are using to have more information on the AT commands syntax, parameters, and parameters range.

In this guide is used the notation [x]/[y] to refer to documents of different modules.

See the document in accordance with your module.

Refer to document [3] in accordance with the module that you are using to have information on the hardware. For example serial ports, GPIO pins... etc.

Refer to document [18] to have detailed information on the audio architecture provided by the modules.

After power on, the module is ready to receive AT commands on its Main Serial Port. Its second serial port, called Auxiliary, is used for factory test.

For example, type in the following AT command to verify if the DTE/DCE connection is working.

3.1.1.1. RTS control line

3.1.1.1.1. 2G Modules

The RTS control line indicates permission to the DCE (module) to send data to the DTE (user equipment). The module every GSM TDMA frame (4.61 ms) checks the RTS (output) of DTE. As soon as the RTS of the DTE is detected as not asserted, the module immediately stops the transmission of the bytes toward the DTE.

RTS=ON, asserted, DCE can transmit

RTS=OFF, not asserted,

DCE

Fig. 2: RTS Control Line

The maximum number of characters that Telit Module can send to the DTE after the transition

RTS asserted to RTS NOT asserted depends upon the used serial port speed. In any case, to take into account delays due to software tasks priorities it is necessary to consider a detection interval equal to 4.61 x 2 = 9.22 ms.

Example:

 at 115200 8N1 the maximum number of transmitted characters (bytes) by DCE is 107:

115200 8N1 => 115200 bit/s = 11520 char/s = 11.52 char/ms = 106.2 char/GSM frame x 2; at 57600 8N1 the maximum number of transmitted characters (bytes) by DCE is 54; at 9600 8N1 the maximum number of transmitted characters (bytes) by DCE is 9.

For the GE910 products (no V3) the number of transmitted characters is formed by two quantities:

288 characters: the number is fixed, regardless the selected speed,

53 is the max number of characters that are transmitted when the software detects the

RTS transition after the max interval time equal to 4.61 ms. In this example the used speed is 115200 bits/s,

 in this example, the maximum number of transmitted characters is: 288 + 53 = 341.

3.1.1.1.2. 3G Modules

HE910 Series

RTS control line indicates permission to the DCE (module) to send data to the DTE (user equipment). The low-high RTS transition generates an interrupt signal. Between the RTS transition and the interrupt signal recognition, the module can send at most one character toward DTE.

Suppose that the HE910 module is in ONLINE Mode and the DTE forces the RTS control line to

high, see Fig. 2 . The data flow from the module to the DTE (download) is stopped. At the same

time, the CTS control line is low - see Fig. 3 -, it means that the module can receive data from

DTE (upload). Follow the steps below to force the module in the COMMAND Mode:

Enter the escape sequence: +++

Force the RTS to low. The Tx buffer of the module will be emptied, and the OK message will be displayed.

Now, the module is in COMMAND Mode.

3.1.1.2. CTS control line

The CTS control line indicates permission to the DTE (user equipment) to send data to the DCE

(module). The CTS (output) of the DCE is not asserted when the data in its receiver buffer is greater than 75% of its capacity, the DTE transmission is stopped. The CTS is asserted when data in the receiver buffer of the module is lower than 25% of its capacity, the DTE transmission starts again.

3.1.17. MSISDN

MSISDN is a number uniquely identifying a subscription in a GSM or UMTS mobile network.

MSISDN is defined by the ITU-U Recommendation [12] which defines the numbering plan: a number uniquely identifies a public network termination point and typically consists of three fields,

CC (Country Code), NDC (National Destination Code), and SN (Subscriber Number), up to 15 digits in total.

3.1.17.1. 2G Modules

The following AT command can be used to store the MSISDN on the assigned field

(EF_MSISDN) of the SIM card.

AT+CRSM=<command>[,<file id>[,<P1>,<P2>,<P3>[,<data>]]]

Using this command, the user needs to know the structure of the field used by the SIM card to storage the MSISDN number, refer to [5], [13]. AT#SNUM is an AT command more "user friendly", it is valid also for USIM card. See the following example:

Before entering the MSISDN in international phone number format, it is mandatory to enter the

command AT#ENS=1. It enables the features described on § 3.1.25.

AT#ENS=1

OK

Write phone number and memo string.

AT#SNUM=1,"+393X912Y45Z7","MY NUMBER"

3.1.21. Signal Strength & Quality

Assume that the module is registered on a network that provides 2G or 3G technology. The following AT command returns the received signal strength & quality giving an indication about the radio link reliability.

AT+CSQ

Assume that the antenna is not connected to the module or network coverage is not present at all.

0 = <ber> = Bit Error Rate

Now, a wrong parameter is entered just to see the result format when Verbose Extended Error result is enabled:

AT+CSQ?

+CME ERROR: operation not supported

3.1.22. Fast Network Status Check

Once the module is registered on a network, does not matter about the technology (2G or 3G), it is useful to know the received signal strength and the network on which the module is registered.

This information is gathered by means of the following standard AT commands: +CREG, +COPS and +CSQ. These commands are not fast in the response due to network response time, especially the +COPS command. If the user objective is to keep his application as general as possible, he can use the standard AT command above mentioned.

Telit's modules provide proprietary AT commands to gather all the information in a faster and simpler way, they are:

AT#MONI

AT#SERVINFO

AT#MONI and AT#SERVINFO commands should be used only to collect network name and signal strength information. To check if the module is registered or it is looking for a suitable network to register on, use +CREG command. In fact, if the network signal is too weak and module loses the registration, until a new network is found the two commands report the last measured valid values and not the real ones. The TA (timing advance parameter) is valid only during a call.

Check network registration with +CREG command. When module is registered, query the module for network operator name and signal strength with AT#MONI command.

3.1.22.1. 2G Modules

The following examples are valid also for modules providing 3G Technology when they are forced in GSM mode by means of the AT+WS46=12 command.

Assume that the antenna is connected to the module and only serving cell information is needed.

Check if the module is using 2G Technology.

AT+COPS?

+COPS: 0,0,"I TIM",0

OK

Yes, it is using 2G Technology. Only the modules providing 2/3G Technologies return the last parameter. It gives information on access technology.

3.1.32. Set Audio Path Active

The present chapter gives a short description about the AT commands that manage the HS and

HF audio paths provided by the modules. Not all modules provide two audio paths, see document

[3]. The modules that provide two audio paths feature the capability to switch between them using software or hardware mode.

When your module provides two physical audio paths, use the following AT command to switch between them:

AT#CAP=<n>

OK

Examples 1:

AT#CAP=2

OK

Examples 2

AT#CAP=1

OK

Examples 3

AT#CAP=0

OK

Use software mode to select HS audio path

Use software mode to select HF audio path

Use hardware mode to select audio path

After entering the previous command select the audio path by means of the pin AXE, refer to [3]:

 pin AXE = HIGH to select HS audio path. pin AXE = LOW to select HF audio path.

The audio paths can be switched also during a call in both ways. When hardware control is not used, AXE pin can be left unconnected.

3.1.32.1. 2G Modules Software Version 13.xx.xxx

AT#CAP=<n>

is a dummy command, returns OK response and no actions are performed by the module. It has been introduced for backward compatibility reasons.

3.1.32.2. 3G Modules

AT+FCLASS=0

has been executed).

ATD+39404X92XYX

CONNECT 9600

The ATD response is returned when the modem handshake is over; it takes an interval of time depending from several factors (Network Operator, communication speed, etc.). Wait for this time before doing anything: when the module is doing the handshake, entering any character closes the handshake and aborts the call.

3.1.39. Disconnect Data Call

During the data call, the module is in ONLINE Mode (ON Line) and if any AT command is entered it is discarded and not executed. Before typing in the ATH command to close the call, the Escape

Sequence (+++) must be used to enter the COMMAND Mode. No characters must be entered between two consecutive "+" characters forming the Escape Sequence.

Assume that a CSD Data Call is in progress. To exit the ONLINE Mode, do the following actions:

Enter the Escape Sequence: +++

AT+CLIR?

+CLIR: 0,4

OK

<n> = 0 = CLIR module facility in accordance with CLIR Network Service

<m>= 4 = CLIR temporary mode presentation allowed (it is the facility status on the Network)

The <m> parameter reports the status of the service at Network level. If the CLIR service is not provisioned by the Network, then it is not possible to use this service and changing the first parameter <n> will not change the CLI presentation to the other party behavior of the Network.

4.1.3.2. Restrict/Allow Caller Line ID Indication

Use the following AT command to enable or disable the presentation of the CLI to the called party.

AT+CLIR=<n>

1.24. SMS Management

The modules provide the SMS Service to store, send, receive, and delete a SMS, which is a short text message up to 160 characters long. Before using the SMS messages, you must configure the

Short Message Service.

4.1.7. Select SMS Format Type

The Telit Module supports two SMS formats:

PDU mode

Text mode

The module uses the PDU format to send a message on the air. The PDU mode enables the user to edit the message in PDU format. If the user is familiar with PDU encoding, he can operate with

PDU by selecting that mode and use the appropriate commands.

The present document uses the Text mode to explain how to operate with SMS. Here is the AT command to select the mode.

AT+CMGF=<mode>

Examples

Check the supported range of values:

AT+CMGF=?

+CMGF: (0,1)

OK

Set up Text Mode for the SMS:

AT+CMGF=1

OK

This setting is stored and remains active until the module is turned OFF.

4.1.7.1. Set Text Mode Parameters

When SMS format is Text mode, the SMS parameters that usually reside on the header of the

PDU must be set apart with the +CSMP command.

AT+CSMP=<fo>,<vp>,<pid>,<dcs>

1.26. GSM Power Saving Modes

The Telit Modules provide a function that reduces the power consumption during the period when they are in IDLE state (waiting for a call), allowing a longer activity with a given battery capacity.

The power saving function can be configured in several modes in accordance with the user needs.

In accordance with the response of the

AT+CFUN=?

Command, you can know the Power Saving

Modes supported by the version of your Telit Module, refer to the table below:

Modules Software Versions AT+CFUN=?

2G

3G

10.01.xxx, 13.00.xxx, 16.01.xxx

12.00.xxx

+CFUN: (0,1,2,4,5,7,9,10,11),(0, 1)

OK

+CFUN: (0,1,4,5,7,9),(0, 1)

OK

Tab. 4: CFUN Modes & Software Versions

Use the following AT command to set the power saving mode:

AT+CFUN=[<fun>[,<rst>]]

Check the current mode:

AT+CFUN?

+CFUN: 1

module with full functionality and power saving disabled (factory setting)

OK

4.1.28. Some clarifications

1. When the module is powered ON the power saving function is disabled (CFUN=1, factory setting) to guarantee the radio functionality and data exchange between the module and the user device. Therefore, the needed CFUN mode command should be entered after every power ON.

2. The radio power ON/OFF activities require a delay between consecutive activation of the following CFUN commands:

CFUN=1

CFUN=4 or CFUN=1

CFUN=4

CFUN=1

CFUN=1

CFUN=10 or CFUN=1

CFUN=11 or CFUN=1

CFUN=10

CFUN=11

It is suggested to use a delay of 10 sec.

3. If the entered CFUN command does not turn off the radio functionality, the power saving function does not affect the network activity of the module. During the power saving mode the module remains registered on the network and reachable for incoming calls, SMS, etc. If an

1vv0300784 Rev. 19 Page

103

of

168

17-01-25 103

incoming call arrives during the power saving, the module will wake up and proceed normally to manage the call.

4. Assume that the module is in power saving mode. The paging time range is 0.5 ÷ 2.1 sec, it depends upon DRX time set by the network; when the module wakes up from the power saving mode, it takes a maximum of 150 ms before checking the DTR line coming from the DTE. If a command is received during the power saving, the module needs at least 0.5÷2.1 sec +150 msec to be ready. Hence, use a delay of at least 2250 msec between the port opening

(DTR=ON) and command sending.

5. The CFUN mode can be saved into the selected profile only if the AT+CFUN command is entered into the module through the AT0 parser (Instance #1, refer to documents [10], [22]).

4.1.29. CFUN=0 and 3G Modules

For HE910 series the behavior of the CFUN=0 is conditioned by the setting of the AT#ENS

command, refer to § 3.1.25.3, and 3.1.25.4.

AT#ENS=0

AT#ENS=1

CFUN=0 has the standard functionality

CFUN=0 has the same functionality of CFUN=4

4.1.30. CFUNs and the Main Serial Port

This chapter describes the relation between the CFUN modes and the control lines (RTS, CTS

refer to § 1.6) of the Main Serial Port (hereafter called AT interface). The § 4.1.31 describes the

wake up events (for example, unsolicited result code) that force the module to exit from the power saving mode temporarily or permanently.

CFUN=2, CFUN=4

These CFUN modes do not interact with the control serial lines of the AT interface.

Type in CFUN=2, the module disables Tx.

Type in CFUN=4, the module performs network deregistration, and SIM deactivation.

CFUN=0, CFUN=9

Here is the starting control lines configuration, the AT interface is working.

<DSR=ON>, RI=OFF, DCD=OFF, <CTS=ON>, RTS=ON (or OFF), DTR=ON

Type in CFUN=0 or CFUN=9. The module enters the NON-CYCLIC SLEEP mode, and the AT interface is no longer accessible. Here is the new control lines configuration.

<

DSR=OFF

>, RI=OFF, DCD=OFF, <

CTS=OFF

>, RTS=ON (or OFF), DTR=ON.

Power saving mode is identified by <DSR=OFF>, <CTS=OFF>. Do not send further characters, they remain in the input buffer and may delay the output of an unsolicited result code.

The RTS line toggling forces the module to exit power saving and enter CFUN=1 mode. The

AT interface is again accessible.

The power saving mode (0 or 9) does not affect the radio activities of the module. It remains registered on the network and reachable for incoming calls or SMS. If a call incomes during the power saving mode, the module will wake up, enters CFUN=1 mode, and proceeds normally with the unsolicited incoming call code.

CFUN=7

Here is the starting control lines configuration, the AT interface is working.

<DSR=ON>, RI=OFF, DCD=OFF, <CTS=ON>, RTS=ON (or OFF), DTR=ON

Type in CFUN=7, the module enters the CYCLIC SLEEP mode. It sets periodically the CTS control line to ON to enables the AT interface for a short time. The period, between two consecutive CTS

OFF

ON transitions, extends from some sec to some tens of sec, its variability depends on the internal timing of the module. If characters are recognized on the AT interface, the module stays

active for about 2 sec after the last character has been sent or received, see

Fig. 4.

The module exits CYCLIC SLEEP mode only if AT+CFUN=1 is entered.

The power saving mode 7 does not affect radio activities of the module. It remains registered on the network and reachable for incoming calls or SMS. If call incomes during the power saving mode, the module will wake up, proceed normally with the unsolicited incoming call code, and after that enters again CFUN=7 mode.

<DSR=ON>, RI=OFF, DCD=OFF, <CTS=ON>, RTS=ON (or OFF), DTR=ON

Type in CFUN=5. The module has full functionality, and the power saving mode is enabled.

To force the module in power saving mode the DTE must set DTR control line to OFF.

Here is the new control lines configuration.

<DSR=OFF>, RI=OFF, DCD=OFF, <CTS=OFF>, RTS=ON (or OFF), DTR=OFF

The AT interface is no longer accessible. Power saving mode is identified by <DSR=OFF>,

<CTS=OFF>.

The module is in power saving mode. The DTE must set the DTR control line to ON, and wait that the module sets the CTS/DSR control lines to ON, before sending any AT command. Now, the AT interface is accessible, but the module is still in CFUN=5 mode. Enter CFUN=1 to exit

CFUN=5 mode.

The module will go back in the power saving mode when the DTE sets DTR line to OFF.

The power saving mode 5 does not affect the radio functionalities of the module. It remains registered on the network and reachable for incoming calls or SMS. If call incomes during the power saving mode, the module will wake up, proceed normally with the unsolicited incoming call code, and after that enters again CFUN=5 mode, it is a CYCLIC SLEEP mode.

CFUN=10

Enter CFUN=10. The module is detached from the network (TX and RX are disabled), the SIM is deactivated, and the power saving mode is enabled.

To force the module in power saving mode the DTE must set DTR control line to OFF.

Here is the new control lines configuration.

<

The module is in power saving mode. The DTE must set the DTR control line to ON, and wait that the module sets the CTS/DSR control lines to ON, before sending any AT command. Now, the AT interface is accessible, but the module is still in CFUN=10 mode.

Enter CFUN=1 to exit CFUN=10 mode.

The module will go back in the power saving mode when the DTE sets DTR line to OFF.

CFUN=11

Here is the starting control lines configuration, the AT interface is working.

<DSR=ON>, RI=OFF, DCD=OFF, <CTS=ON>, RTS=ON (or OFF), DTR=ON

Enter CFUN=11. The module is detached from the network (TX and RX are disabled), the SIM is deactivated, and the power saving mode is automatically entered. Here is the new control lines configuration.

<

DSR=OFF

>, RI=OFF, DCD=OFF, <

CTS=OFF

>, RTS=ON (or OFF), DTR=ON

The AT interface is no longer accessible. Power saving mode is identified by <DSR=OFF>,

<CTS=OFF>

The module is in power saving. It monitors the RTS toggling every N seconds to change the current AT interface state (accessible/not accessible). The range of N extends from some sec to some tens of sec, its variability depends on the internal timing of the module. In any case, the CFUN=11 mode is still active.

When the AT interface is accessible, enter CFUN=1 to exit CFUN=11mode.

4.1.31. CFUNs and Wake up Events

It is suggested to read § 4.1.30 before reading the

Tab. 5

. See CFUN examples in

§ 4.1.32.

The Tab. 5 shown in the next page summarizes the behavior of the CFUN modes in relation with

specific wake up event. The shaded row lists the available CFUN modes; the shaded Wake up

Events column lists the possible events. Therefore, the cell on the crossing between the selected

CFUN mode column and the row of the selected wake up event shows the new CFUN mode entered by the module after the occurrence of the wake up event. It is assumed that the wake up events occur when the module is in power saving mode.

The "N/A" abbreviation indicates that the specific wake up event shown in the table is not applicable to the selected CFUN. For example, incoming voice call is not applicable when the module is in CFUN=4 mode because the radio is turned off.

"The new mode depends on URC" means that the final CFUN mode of the module depends on the type of the URC. For example, if the wake up event is the extraction of the SIM, #QSS URC

is not generated if the module is in CFUN=4 mode because the SIM is deactivated, see § 4.1.32.1.

1.27. GPIO Pins

Telit Modules provide various GPIO pins, which can be configured, by means of the AT commands, as showed hereafter:

Inputs,

Outputs,

“Alternate Functions”.

User applications, through GPIO AT commands, can control external user equipment connected to GPIO pins. Simple or no circuitries are needed to perform the required hardware interface.

The GPIO setting is not saved on power off. At power on, repeat the GPIO setting.

For detailed GPIO pins descriptions refer to document [3] in accordance with the used module.

4.1.33. Set GPIO Pin as OUTPUT

Use the following AT command to set a GPIO as output with Low or High status value.

AT#GPIO=<pin>,<value>,1

Set GPIO8 pin as Output with Low status:

AT#GPIO=8,0,1

OK

GPIO8 pin is set in output; its status is Low

Set GPIO8 pin as Output with High status:

AT#GPIO=8,1,1

OK

GPIO8 pin is set in output; its status is High

4.1.34. Set GPIO Pin as INPUT

Use the following AT command to set a GPIO as input. A dummy value must be specified for pin status value.

AT#GPIO=<pin>,<dummy_value>,0

Example

Set GPIO9 pin as Input:

AT#GPIO=9,0,0

OK

GPIO9 pin is set in input

4.1.35. GPIO Pin Status

Use the following AT command to check the pin status.

1vv0300784 Rev. 19 Page

130

of

168

17-01-25 130

AT#GPIO=<pin>,2

Set GPIO8 pin as output with Low status.

AT#GPIO=8,0,1

OK

Set GPIO9 pin as input.

AT#GPIO=9,0,0

OK

Now, physically connect GPIO8 with GPIO9, and check the GPIO9 status.

AT#GPIO=9,2

#GPIO: 0,0

GPIO9 pin status is Low, as commanded by GPIO8.

Set GPIO8 pin as output with High status.

AT#GPIO=8,1,1

OK

Check the GPIO9 status.

AT#GPIO=9,2

#GPIO: 0,1

GPIO9 pin status is High, as commanded by GPIO8.

Check the GPIO8 status.

AT#GPIO=8,2

#GPIO: 1,1

GPIO8 pin is set in Output direction and its status is High.

Check the supported range of pin, mode and direction. The command response depends on the used module.

AT#GPIO=?

#GPIO: (1-13),(0-2),(0-2)

OK

The AT command response is function of the pin direction:

 input: the command response indicates the current input status output: the command response indicates the last setting of the pin status

If GPIO pin is set to Alternate Function mode, the reported status is not valid.

4.1.36. GPIO & Alternate Function

The following paragraphs describe the GPIO dedicated to support the Alternate Function configuration, and the AT commands used to perform the setting. For a detailed documentation about the Alternate Functions and GPIO circuitry refer to document [3] in accordance with the used module.

The user application by means of the GPIO4 can control the transmitter of the module. Use the following AT command to set the GPIO4 in RF Transmission Control Alternate Function mode.

AT#GPIO=4,<dummy_value>,2

1.28. Clock and Alarm Functions

The modules provide Real Time Clock and Alarm features. The next sub-chapters describe some examples to show the AT commands used to:

Set up the right time

Check the actual time

Set up an alarm time

Delete an alarm time

Check/Update module clock before using the Alarm feature.

Once woken up, the module can have several "alarm behaviors type" in accordance with the

<type> parameter used to set up the alarm by means of the AT+CALA command:

Automatically wakes up from shutdown and becomes operative.

Automatically wakes up from shutdown and enters dedicated Alarm Status. The module does not look for or try to register on any network, it performs only previously programmed alarm actions. It can receive AT commands to become operative or shutdown immediately.

Send an unsolicited code "+CALA: <text>" on the serial port until the 90 sec timeout expires or a special wake up command is received.

The programmed unsolicited code "AT+CALA:<user_text> alerts the user application that the

"alarm time" is expired.

Play an alarm tone until the 90 sec timeout expires or a special wake up command is received. The playing of the alarm tone alerts the user.

Rise the GPIO6 pin until the 90 sec timeout expires or a special wake up command is received. The GPIO6 pin can be used to wake up a user device at the desired time.

The Alarm time refers to the local time, regardless the time zone set by AT+CCLK command.

If GPIO6 pin is used as ALARM OUTPUT, it must be configured in "Alternate

Function" mode (see §

4.1.36.3) or else the pin will not respond to the Alarm

settings.

If the unsolicited code +CALA: <text> is used, the serial port speed must be

configured as needed (see § 1.7) and stored in the active profile (see AT&W

command), to perform the module power on with the desired serial port speed. Be careful, at the Alarm wake up, the module will start with the default port speed that could be different from the speed set on DTE.

4.1.38.5. Stop Alarm

When the "Alarm Time" is reached, the module starts the "Alarm Activity" according to the previous

"Alarm Setting". There are three ways to stop the "Alarm Activity".

Shutdown the module

Exit from “Alarm Activity” and enter the “Normal mode”

Let the “Alarm Activity” continue until the 90 sec timeout is expired

U se the following AT command, the module exits “Alarm Activity” and shuts down.

AT#SHDN

OK

Exit from the Alarm Status and Enter the Normal mode:

Use the following AT command, the module exits “Alarm Activity” and enters “Normal mode”.

AT#WAKE=0

OK

4.1.38.6. Alarm Status

When the "Alarm Time" is reached, the module wakes up and starts the "Alarm Activity". During this period no "Network Activity" is performed: the user application can perform some operations without register the module on the network. To check if the module is in the "Alarm" or in the

"Normal mode" status, use the following AT command.

AT#WAKE?

When the module is in the "Alarm" mode, no network activities are allowed: it is not possible to receive or send calls, SMS and any services. The only commands that are accepted by the module are AT#WAKE and AT#SHDN.

4.1.38.7. A simple Alarm Application

In this example, it is assumed that the user is developing a Meteorological Unit using a batterypowered module. The Meteorological Unit requirement is to measure the weather conditions every hour and send an SMS message to the main server, indicating the weather status just measured.

The user application should minimize the power consumption, because the Meteorological Unit will be installed in a remote location and its battery must last as long as possible. To minimize the power consumption, the user application should shut the module down as well the equipment that does not need to be powered up all the time. The module and the equipment will be woken up every hour for just the time needed to measure and send the required SMS message.

Set up the current time.

AT+CCLK="02/11/07,12:24:30+01"

OK

Set up the next alarm to program the GPIO6 pin which is responsible to power up the user equipment that does not need to be powered up all the time. <type> parameter is 6.

AT+CALA="02/11/07,13:24:30+01",0,6,"TIME TO MEASURE

& SMS…!"

OK

Shut down the module and the equipment.

AT#SHDN

OK

After an hour, when the programmed alarm time is reached, the module turns itself on in "Alarm

Mode", forces high the GPIO6 pin, which turns on the power supply of the equipment and sends the unsolicited code to DTE every three seconds:

4.1.40. 4G Modules and Default/Dedicated EPS Bearers

In GPRS and 3G networks, the data session is established by means of the Packet Data Protocol

(PDP) Context procedure. Before the PDP context can be established, the module must do an

Attach procedure, which communicates to the SGSN (Serving GPRS Support Node) that the module has powered up. After the Attach procedure is completed, the module can do the first PDP

Context procedure that will establish the data session, and allocate an IP address to the module.

This PDP Context will have a QoS associated with it based on the current needs. If the module needs to have multiple data sessions, it will do a second PDP Context activation, and so on.

In LTE (4G) modules there are two types of data session setups.

Default Evolved Packet System (EPS) Bearer.

When UE attaches to the network for the first time, it will be assigned default bearer that remains as long as UE is attached. UE can have additional default bearers as well. Each default bearer comes with a separate IP address. Default bearer does not have specific QoS (non-GBR bearer).

Dedicated Evolved Packet System (EPS) Bearer.

It is created when the requested service cannot be fulfilled through default bearer.

Some services require a high level of QoS like VoIP, video etc. Therefore, network creates a dedicated bearer with required QoS (can be GBR or non-GBR). Dedicated bearer does not require separate IP address, only additional default bearer needs an

IP address and therefore dedicated bearer is always linked to one of the default bearer established previously.

To have information on AT commands syntax and related parameters refer to document [26].

The functionalities (Data, IMS) of the Default PDP context assigned by the network, depend on the Network Operator.

When the <p_cid>=1 is associated to a user APN, i.e. the APN is not empty, that APN is used by the module during the 4G registration and data connection procedures. Some Network Operators could not allow the 4G registration when the user APN is used, and they could force a detach. If this happens, it is recommended to set the user APN on a <p_cid> different from 1 and keep on

<p_cid> 1 the empty APN.

4.1.40.1.1. Change a Default EPS Bearer at UE Power on

Following these steps, you can substitute the Default EPS Bearer with a user PDP Context.

4.1.40.2. Establish a Default EPS Bearer

The following AT commands can establish a Default EPS Bearer:

AT+CGACT

Establishes a Default EPS Bearer. If the module (UE) is not attached, it does the

Attached procedure and then activates the PDP Context.

AT#SGACT

Establishes a Default EPS Bearer, and opens a Network Interface to use the TCP/IP protocol running on the UE (IP Easy connection, see document [4]). If the <cid> used by the AT#SGACT command is already active, the command opens only a Network

Interface.

ATD

Establishes a Default EPS Bearer. It provides a dialup connection: PPP protocol is used to exchange data between the PC (or Application Equipment) and the module

(UE), the TCP/IP stack is running on the module.

AT#NCM

Establishes a Default EPS Bearer, refer to chapter 4.1.40.6

AT#MBIMCFG

Refer to document [23].

The AT commands shown in this chapter cannot use together the same <cid>.

4.1.40.4. AT#DUALAPN

Assume that the UE is registered on a 4G network. If the UE tries to establish two Default EPS bearers with the same APN and PDP type, the second PDN Connectivity Request returns an

ERROR message. In general, some 4G Network Operators does not support multiple Default EPS bearers for a single APN.

This could be a limitation for those user applications requiring the activation of two PDP contexts connected to two different <p_cid>.

To overcame this limitation, use the #DUALAPN=0 mode that allows you, for example, to assign to <p_cid>=2 the same APN and PDP type already in use with <p_cid>=1. The module routs the

<p_cid>=2 to the <p_cid>=1; therefore, the IP address of both <p_cid> will be the same. See the examples in the following sub-chapters.

I. If the module is in #DUALAPN=0 mode, the AT commands shown in

chapter 4.1.40.2 cannot use two <p_cid> having the same IP address.

#DUALAPN=0 mode is by default. II.

5. FIRMWARE UPDATE TOOL

Telit Modules support the Over-The-Air (OTA) update that is the wireless delivery of new firmware to the modules.

In the case the user needs to perform the firmware upgrading by means a serial line, Telit provides the suitable tool. It is suggested to provide a serial interface on the user printed circuit board (on which Telit Module is soldered) to perform the physical connection between the module and

Windows-PC, or use the Telit Evaluation Kit (EVK2), refer to document [6], that is equipped with serial interfaces.

The following paragraphs describe the Telit tool.

GT terminals are completely cased modems (refer to Applicability Table) and provide the standard RS-232 port that can be used to perform firmware update.

1.30. Xpf tool

The Xfp tool, running on Windows-PC, allows the user to update the firmware of the module. The tool erases the flash memory content, and then downloads the new firmware on the erased flash memory.

1)

2)

3)

5.1.1. Update Procedure

Here is the procedure to update the firmware:

Install on the Windows-PC the Xfp tool and the USB FLASH driver.

Power OFF the module.

Run Xfp tool. The following Xpf info appears. The info shows some products that are out of the scope of the present document.
