80446ST10707A Rev . 0– 2015-11-03
AT COMMANDS
The Telit wireless module family can be controlled via the serial interface using the standard AT commands
1 . The Telit wireless module family is compliant with:
1.
Hayes standard AT command set, in order to maintain the compatibility with existing SW programs.
2.
3GPP TS 27.007 specific AT command and GPRS specific commands.
3.
3GPP TS 27.005 specific AT commands for SMS (Short Message Service) and CBS (Cell
Broadcast Service)
Moreover Telit wireless module family supports also Telit proprietary AT commands for special purposes.
The following is a description of how to use the AT commands with the Telit wireless module family.
3.1.
Definitions
The following syntactical definitions apply:
<CR> Carriage return character , is the command line and result code terminator character, which value, in decimal ASCII between 0 and 255,is specified within parameter S3 . The default value is 13.
<LF> Linefeed character , is the character recognised as line feed character. Its value, in decimal ASCII between 0 and 255, is specified within parameter S4 . The default value is
10. The line feed character is output after carriage return character if verbose result codes are used ( V1 option used ) otherwise, if numeric format result codes are used ( V0 option used) it will not appear in the result codes.
<...> Name enclosed in angle brackets is a syntactical element. They do not appear in the command line.
[...] Optional subparameter of a command or an optional part of TA information response is enclosed in square brackets. Brackets themselves do not appear in the command line.
When subparameter is not given in AT commands which have a Read command, new value equals to its previous value. In AT commands which do not store the values of any of their subparameters, and so have not a Read command, which are called action type commands, action should be done on the basis of the recommended default setting of the subparameter.
1
The AT is an ATTENTION command and is used as a prefix to other parameters in a string. The AT command combined with other parameters can be set up in the communications package or typed in manually as a command line instruction.combined with other parameters can be set up in the communications package or typed in manually as a command line instruction.

80446ST10707A Rev . 0– 2015-11-03
AT Command Syntax
The syntax rules followed by Telit implementation of either Hayes AT commands, GSM commands are very similar to those of standard basic and extended AT commands
There are two types of extended command:
Parameter type commands . This type of commands may be “set” (to store a value or values for later use), “read” (to determine the current value or values stored), or “tested”
(to determine ranges of values supported). Each of them has a test command (trailing =?
) to give information about the type of its subparameters; they also have a Read command
(trailing ?
) to check the current values of subparameters.
Action type commands . This type of command may be “executed” or “tested”.
•
“executed“ to invoke a particular function of the equipment, which generally involves more than the simple storage of a value for later use
•
“tested” to determine: if subparameters are associated with the action, the ranges of subparameters values that are supported; if the command has no subparameters, issuing the correspondent Test command
(trailing =?
) raises the result code “ ERROR ”.
Note: issuing the Read command (trailing ?
) causes the command to be executed. whether or not the equipment implements the Action Command (in this case issuing the correspondent Test command - trailing =?
- returns the OK result code), and, if subparameters are associated with the action, the ranges of subparameters values that are supported.
Action commands don’t store the values of any of their possible subparameters.
Moreover:
The response to the Test Command (trailing =?
) may be changed in the future by Telit to allow the description of new values/functionalities.
If all the subparameters of a parameter type command +CMD are optional, issuing
AT+CMD=<CR> causes the OK result code to be returned and the previous values of the omitted subparameters to beretained.
String Type Parameters

A string, either enclosed between quotes or not, is considered to be a valid string type parameter input. According to V25.ter space characters are ignored on the command line and may be used freely for formatting purposes, unless they are embedded in numeric or quoted string constants; therefore a string containing a space character has to be enclosed between quotes to be considered a valid string type parameter (e.g. typing AT+COPS=1,0,”A1” is the same as typing
AT+COPS=1,0,A1 ; typing AT+COPS=1,0,”A BB” is different from typing AT+COPS=1,0,A
BB ).
A string is always case sensitive.
A small set of commands requires always to write the input string parameters within quotes: this is explicitly reported in the specific descriptions.
3.2.2.
Command Lines
A command line is made up of three elements: the prefix , the body and the termination character .
The command line prefix consists of the characters “ AT ” or “ at ”, or, to repeat the execution of the previous command line, the characters “ A/ ” or “ a/ ” or AT#/ or at#/ .
The termination character may be selected by a user option (parameter S3), the default being
<CR> .
The basic structures of the command line are:
•
ATCMD1<CR> where AT is the command line prefix, CMD1 is the body of a basic command (nb: the name of the command never begins with the character “ + ”) and <CR> is the command line terminator character
•
ATCMD2=10<CR> where 10 is a subparameter
•
AT+CMD1;+CMD2=, ,10<CR> These are two examples of extended commands (nb: the name of the command always begins with the character “ + ”
). They are delimited with semicolon. In the second command the subparameter is omitted.
•
+CMD1?<CR> This is a Read command for checking current subparameter values
•
+CMD1=?<CR> This is a test command for checking possible subparameter values
These commands might be performed in a single command line as shown below:
ATCMD1 CMD2=10+CMD1;+CMD2=, ,10;+CMD1?;+CMD1=?<CR> anyway it is always preferable to separate into different command lines the basic commands and the extended commands; furthermore it is suggested to avoid placing several action commands in
2 The set of proprietary AT commands differentiates from the standard one because the name of each of them begins with either “ @ ”, “ # ”, “ $ ” or “*”. Proprietary AT commands follow the same syntax rules as extended commands

the same command line, because if one of them fails, then an error message is received but it is not possible to argue which one of them has failed the execution.
If command V1 is enabled (verbose responses codes) and all commands in a command line has been performed successfully, result code <CR><LF>OK<CR><LF> is sent from the TA to the
TE, if subparameter values of a command are not accepted by the TA or command itself is invalid, or command cannot be performed for some reason, result code <CR><LF>ERROR<CR><LF> is sent and no subsequent commands in the command line are processed.
If command V0 is enabled (numeric responses codes), and all commands in a command line has been performed successfully, result code 0<CR> is sent from the TA to the TE, if sub-parameter values of a command are not accepted by the TA or command itself is invalid, or command cannot be performed for some reason, result code 4<CR> and no subsequent commands in the command line are processed.
In case of errors depending on ME operation, ERROR (or 4 ) response may be replaced by +CME
ERROR: <err> or +CMS ERROR: <err> .
NOTE:
The command line buffer accepts a maximum of 400 characters. If this number is exceeded none of the commands will be executed and TA returns ERROR .

Information Responses And Result Codes
The TA response, in case of verbose response format enabled, for the previous examples command line could be as shown below:
• information response to +CMD1?
<CR><LF>+CMD1:2,1,10<CR><LF>
• information response to +CMD1=?
<CR><LF>+CMD1(0-2),(0,1),(0-15)<CR><LF>
• final result code <CR><LF>OK<CR><LF>
Moreover there are other two types of result codes:
•
result code s that inform about progress of TA operation (e.g. connection establishment
CONNECT )
•
result code s that indicate occurrence of an event not directly associated with issuance of a command from TE (e.g. ring indication RING ).

Command Response Time-Out
Every command issued to the Telit modules returns a result response, if response codes are enabled (default). The time needed to process the given command and return the response varies, depending on the command type. Commands that do not interact with the SIM or the network, and only involve internal setups or readings, have an immediate response.Commands that interact with the SIM or the network could take many seconds to send a response, depending on
SIM configuration (e.g., number of contacts stored in the phonebook, number of stored SMS), or on the network the command may interact with.
Command Issuing Timing
The chain Command -> Response shall always be respected and a new command must not be issued before the module has terminated all the sending of its response result code (whatever it may be).
This applies especially to applications that “sense” the OK text and therefore may send the next command before the complete code <CR><LF>OK<CR><LF> is sent by the module.
It is advisable anyway to wait for at least 20ms between the end of the reception of the response and the issue of the next AT command.
If the response codes are disabled and therefore the module does not report any response to the command, then at least the 20ms pause time shall be respected.
Storage
Factory Profile And User Profiles
The Telit wireless modules stores the values set by several commands in the internal non volatile memory (NVM), allowing to remember this setting even after power off. In the NVM these values are set either as factory profile or as user profiles : there are two customizable user profiles and one factory profile in the NVM of the device: by default the device will start with user profile 0 equal to factory profile.
For backward compatibility each profile is divided into two sections, one base section which was historically the one that was saved and restored in early releases of code, and the extended section which includes all the remaining values.
The &W command is used to save the actual values of both sections of profiles into the NVM user profile.
Commands &Y and &P are both used to set the profile to be loaded at startup. &Y instructs the device to load at startup only the base section . &P instructs the device to load at startup the full profile: base + extended sections .
The &F command resets to factory profile values only the command of the base section of profile, while the &F1 resets to factory profile values the full set of base + extended section commands.

The values set by other commands are stored in NVM outside the profile: some of them are stored always, without issuing any &W , some other are stored issuing specific commands
( +CSAS , #SLEDSAV , #SKTSAV , #ESAV ); all of these values are read at power-up.
The values set by following commands are stored in the profile base section; they depend on the specific AT instance:

AT
Reference
The prefix AT , or
SELINT 2 start a command line to be sent from TE to TA, with the only exception of AT#/ prefix
3GPP TS 27.007 at , is a two-character abbreviation ( ATtention ), always used to
Last Command Automatic Repetition - A/
A/ - Last Command Automatic Repetition
A/ If the prefix A/ or a/
SELINT 2
is issued, the MODULE immediately execute once again the body of the preceding command line. No editing is possible and no termination character is necessary. A command line may be repeated multiple times through this mechanism, if desired.
If A/ is issued before any command line has been executed, the preceding command line is assumed to have been empty (that results in an OK result code).
Note: this command works only at fixed IPR.
Note: the custom prefix AT #/ has been defined: it causes the last command to be executed again too; but it doesn’t need a fixed IPR.

Note: in the query command the class parameter must not be issued.
Note: the difference between call waiting report disabling ( AT+CCWA = 0,1,7 ) and call waiting service disabling ( AT+CCWA = 0,0,7 ) is that in the first case the call waiting indication is sent to the device by network but this last one does not report it to the DTE ; instead in the second case the call waiting indication is not generated by the network. Hence the device results busy to the third party in the
2 nd case while in the 1 st case a ringing indication is sent to the third party.
Note: The command AT+CCWA=1,0 has no effect a non sense and must not be issued..

SELINT 2
Execution command controls the network call hold service. With this service it is possible to disconnect temporarily a call and keep it suspended while it is retained by the network, contemporary it is possible to connect another party or make a multiparty connection.
Parameter:
<n>
0 - releases all held calls, or sets the UDUB (User Determined User Busy) indication for a waiting call. (only from version D)
1 - releases all active calls (if any exist), and accepts the other (held or waiting) call
1X - releases a specific active call X
2 - places all active calls (if any exist) on hold and accepts the other (held or waiting) call.
2X - places all active calls on hold except call X with which communication shall be supported (only from version D).
3 - adds an held call to the conversation
4 - connects the two calls and disconnects the subscriber from both calls (Explicit
Call Transfer (ECT))
Note: "X" is the numbering (starting with 1) of the call given by the sequence of setting up or receiving the calls (active, held or waiting) as seen by the served subscriber. Calls hold their number until they are released. New calls take the lowest available number.
Note: where both a held and a waiting call exist, the above procedures apply to the waiting call (i.e. not to the held call) in conflicting situation.

AT+CFUN= Set command selects the level of functionality in the ME.
[<fun>[,<rst>]]
Parameters:
SELINT 2
<fun> - is the power saving function mode
0 - minimum functionality, NON-CYCLIC SLEEP mode: in this mode, the AT interface is not accessible. Consequently, once you have set <fun> level 0, do not send further characters. Otherwise these characters remain in the input buffer and may delay the output of an unsolicited result code. The first wake-up event, or rising RTS line, stops power saving and takes the ME back to full functionality level <fun>=1 .
1 - mobile full functionality with power saving disabled (factory default)
4 - disable both TX and RX
5 - mobile full functionality with power saving enabled
7 - CYCLIC SLEEP mode: in this mode, the serial interface is periodically enabled while CTS is active. If characters are recognized on the serial interface, the
ME stays active for 2 seconds after the last character was sent or received. ME exits
SLEEP mode only, if AT+CFUN=1 is entered
9 - just as 0 but with different wake-up events (see SW User Guide)
12 – Fast detach
<rst> - reset flag
0 - do not reset the ME before setting it to <fun> functionality level
1 - reset the device. The device is fully functional after the reset. This value is available only for <fun> = 1
Note: issuing AT+CFUN=4[,0] actually causes the module to perform either a network deregistration and a SIM deactivation.
Note: if power saving enabled, it reduces the power consumption during the idle time, thus allowing a longer standby time with a given battery capacity.
Note: to place the module in power saving mode, set the <fun> parameter at value
= 5 and the line DTR (RS232) must be set to OFF . Once in power saving, the CTS line switch to the OFF status to signal that the module is really in power saving condition.
During the power saving condition, before sending any AT command on the serial line, the DTR must be set to ON (0V) to exit from power saving and it must be waited for the CTS (RS232) line to go in ON status.
Until the DTR line is ON , the module will not return back in the power saving condition
Note: the power saving function does not affect the network behaviour of the module, even during the power save condition the module remains registered on the network and reachable for incoming calls or SMS. If a call incomes during the

Set command operated (SIM PIN, SIM PUK, PH-SIM PIN, etc.).
SELINT 2 sends to the device a password which is necessary before it can be
If the PIN required is SIM PUK or SIM PUK2, the <newpin> is required. This second pin, <newpin> will replace the old pin in the SIM.
The command may be used to change the SIM PIN by sending it with both parameters <pin> and <newpin>
Parameters:
<pin> - string type value
<newpin> - string type value.
To check the status of the PIN request use the command AT+CPIN?
Read command reports the PIN/PUK/PUK2 request status of the device in the form:

Parameter:
SELINT 2
<state> - registration state
0 - the indicator is deregistered; there’s no unsolicited result code ( +CIEV URC) automatically sent by the ME to the application, whenever the value of the associated indicator changes; the value can be directly queried with +CIND?
1 - the indicator is registered: an unsolicited result code ( +CIEV URC) is automatically sent by the ME to the application, whenever the value of the
AT+CIND? associated indicator changes; it is still possible to query the value through
+CIND?
(default)
Note: When the ME is switched on all of the indicators are in registered mode.
Read command returns the current value of ME indicators, in the format:

Set command enables/disables sending of unsolicited result codes from TA to TE in the case of indicator state changes (n.b.: sending of URCs in the case of key pressings or display changes are currently not implemented).
Parameters:
<mode> - controls the processing of unsolicited result codes
0 - buffer +CIEV Unsolicited Result Codes.
1 - discard +CIEV Unsolicited Result Codes when TA-TE link is reserved (e.g. on-line data mode); otherwise forward them directly to the TE.
2 - buffer +CIEV Unsolicited Result Codes in the TA when TA-TE link is reserved (e.g. on-line data mode) and flush them to the TE after reservation; otherwise forward them directly to the TE.
3 - forward +CIEV Unsolicited Result Codes directly to the TE; when TA is in on-line data mode each +CIEV URC is stored in a buffer; once the ME goes into command mode (after +++ was entered), all URCs stored in the buffer will be output.

Reference
Note: After AT+CMER has been switched on with e.g. AT+CMER=2,0,0,2 command (i.e. <bfr> is 0), URCs for all registered indicators will be issued only first time, if previous <mode> was 0, for backward compatibility.
Values shown by the indicators will be current indicators values, not buffered ones. Subsequent AT+CMER commands with <mode> different from 0 and
<bfr> equal to 0 will not flush the codes, even if <mode> was set again to 0 before. To flush the codes, <bfr> must be set to 1.
Although it is possible to issue the command when SIM PIN is pending, it will answer ERROR if “message” or “smsfull” indicators are enabled in AT+CIND, because with pending PIN it is not possible to give a correct indication about SMS status. To issue the command when SIM PIN is pending you have to disable
“message” and “smsfull” indicators in AT+CIND first.

AT+CALA=
SELINT 2
Set command stores in the internal Real Time Clock an alarm time with respective
<time>[,<n>[,<type>
[,<text>[,<recurr>
[,<silent>]]]]] settings. It is possible to set up a recurrent alarm for one or more days in the week.
Currently just one alarm can be set.
When the RTC time reaches the alarm time then the alarm starts, the behaviour of the MODULE depends upon the setting <type> and if the device was already ON at the moment when the alarm time had come.
Parameters:
<time> - current alarm time as quoted string
“” - (empty string) deletes the current alarm and resets all the +CALA parameters to the “factory default” configuration
"hh:mm:ss±zz" - format to be used only when issuing +CALA with parameter
<recurr> too.
"yy/MM/dd,hh:mm:ss±zz" - generic format: it’s the same as defined for +CCLK
(see)
<n> - index of the alarm
0 - The only value supported is 0.
<type> - alarm behaviour type
0 - reserved for other equipment use.
1 - the MODULE simply wakes up fully operative as if the ON/OFF button had been pressed. If the device is already ON at the alarm time, then it does nothing
(default).
2 - the MODULE wakes up in "alarm mode" if at the alarm time it was off, otherwise it remains fully operative. In both cases the MODULE issues an unsolicited code every 3s:
+CALA: <text> where <text> is the +CALA optional parameter previously set.
The device keeps on sending the unsolicited code every 3s until a #WAKE or
#SHDN command is received or a 90 seconds timer expires. If the device is in
"alarm mode" and it does not receive the #WAKE command within 90s then it shuts down.
3 - the MODULE wakes up in "alarm mode" if at the alarm time it was off, otherwise it remains fully operative. In both cases the MODULE starts playing the alarm tone on the selected path for the ringer (see command #SRP )
The device keeps on playing the alarm tone until a #WAKE or #SHDN command is received or a 90 s time-out occurs. If the device is in "alarm mode" and it does not receive the #WAKE command within 90s then it shuts down.
4 - the MODULE wakes up in "alarm mode" if at the alarm time it was off, otherwise it remains fully operative. In both cases the MODULE brings the pin
GPIO6 high, provided its <direction> has been set to alarm output, and keeps it

#WAKE command within 90s then it shuts down.
5 - the MODULE will make both the actions as for type=2 and <type>=3 .
6 - the MODULE will make both the actions as for type=2 and <type>=4 .
7 - the MODULE will make both the actions as for type=3 and <type>=4 .
8 - the MODULE wakes up in "alarm mode" if at the alarm time it was off, otherwise it remains fully operative. In both cases the MODULE sets High the
RI output pin. The RI output pin remains High until next #WAKE issue or until a 90s timer expires. If the device is in "alarm mode" and it does not receive the #WAKE command within 90s. After that it shuts down.
<text> - unsolicited alarm code text string. It has meaning only if <type> is equal to 2 or 5 or 6.
<recurr> - string type value indicating day of week for the alarm in one of the following formats:
“<1..7>[,<1..7>[, … ]]” - it sets a recurrent alarm for one or more days in the week; the digits 1 to 7 corresponds to the days in the week (Monday is 1).
“0” - it sets a recurrent alarm for all days in the week.
<silent> - integer type indicating if the alarm is silent or not.
0 - the alarm will not be silent;
1 - the alarm will be silent.
During the "alarm mode" the device will not make any network scan and will not register to any network and therefore is not able to dial or receive any call or SMS, the only commands that can be issued to the MODULE in this state are the
#WAKE and #SHDN , every other command must not be issued during this state.

AT+CBC
SELINT 2
Execution command returns the current Battery Charge status in the format:
+CBC: <bcs>,<bcl> where:
<bcs> - battery status
0 - ME is powered by the battery
1 - ME has a battery connected, and charger pin is being powered
2 - ME does not have a battery connected
3 - Recognized power fault, calls inhibited
<bcl> - battery charge level, only if <bcs>=0
0 - battery is exhausted, or ME does not have a battery connected
25 - battery charge remained is estimated to be 25%
50 - battery charge remained is estimated to be 50%
75 - battery charge remained is estimated to be 75%
100 - battery is fully charged.
Note: <bcs> =1 indicates that the battery charger supply is inserted and the battery is being recharged if necessary with it. Supply for ME operations is taken anyway from VBATT pins.
Note: without battery/power connected on VBATT pins or during a power fault the unit is not working, therefore values <bcs>=2 and <bcs>=3 will never appear.
Note: <bcl> indicates battery charge level only if battery is connected and charger is not connected

New message acknowledgement - +CNMA
+CNMA – New Message Acknowledgement
AT+CNMA Execution command confirms correct reception of a new message (SMS-DELIVER or SMS-STATUS-REPORT) which is routed directly to the TE.
Acknowledge with +CNMA is possible only if the +CSMS parameter is set to 1
( +CSMS=1 ) when a +CMT or +CDS indication is shown.
If no acknowledgement is given within the network timeout (17 seconds), an RP-
ERROR is sent to the network, the <mt> and <ds> parameters of the +CNMI command are then reset to zero (do not show new message indication).
If command is executed, but no acknowledgement is expected, or some other ME related error occurs, final result code +CMS ERROR: <err> is returned.
The AT command syntax and functionalities are different between SMS PDU Mode and SMS Text Mode, as explained below.
(PDU Mode)
AT+CNMA[=<n>[,<l ength>[<CR>PDU is given<ctrl-Z/ESC]]]
Either positive (RP-ACK) or negative (RP-ERROR) acknowledgement to the network is possible. Parameter <n> defines which one will be sent. Optionally
(when <length> is greater than zero) an acknowledgement TPDU (SMS-
DELIVER-REPORT for RP-ACK or RP-ERROR) may be sent to the network. The entering of PDU is done similarly as specified in command Send Message
+CMGS , except that the SMSC address field is not present.
Parameter:
<n> - Type of acknowledgement in PDU mode
0 : send RP-ACK without PDU (same as TEXT mode)
1 : send RP-ACK with optional PDU message.
2 : send RP-ERROR with optional PDU message.
<length> : Length of the PDU message.
Only positive acknowledgement to network (RP-ACK) is possible. (Text Mode)
AT+CNMA

AT+CNMA=?
(Text Mode)

Notes

Test command returns the OK result code.
<n>
1 - In case that a directly routed message must be buffered in ME/TA (possible when +CNMI parameter <mode> equals 0 or 2) or AT interpreter remains too long in a state where result codes cannot be sent to TE (e.g. user is entering a message using +CMGS ), acknowledgement (RP-ACK) is sent to the network without waiting +CNMA command from TE.

(PDU Mode)
Execution command sends to the network a message.
Parameter:
<length> - length of the PDU to be sent in bytes (excluding the SMSC address octets).
7..164
After command line is terminated with <CR> , the device responds sending a four character sequence prompt:
<CR><LF><greater_than><space> (IRA 13, 10, 62, 32) and waits for the specified number of bytes.
Note: the DCD signal shall be in ON state while PDU is given.
Note: the echoing of given characters back from the TA is controlled by echo command E
Note: the PDU shall be hexadecimal format (each octet of the PDU is given as two
IRA character long hexadecimal number) and given in one line.
Note: when the length octet of the SMSC address (given in the PDU ) equals zero, the SMSC address set with command +CSCA is used; in this case the SMSC Typeof-Address octet shall not be present in the PDU .
To send the message issue Ctrl-Z char ( 0x1A hex).
To exit without sending the message issue ESC char ( 0x1B hex).
If message is successfully sent to the network, then the result is sent in the format:
+CMGS: <mr> where

After command line is terminated with <CR> , the device responds sending a four character sequence prompt:
<CR><LF><greater_than><space> (IRA 13, 10, 62, 32)
After this prompt text can be entered; the entered text should be formatted as follows:
- if current <dcs> (see +CSMP ) indicates that GSM03.38 default alphabet is used and current <fo> (see +CSMP ) indicates that 3GPP TS 23.040 TP-User-Data-
Header-Indication is not set, then ME/TA converts the entered text into GSM alphabet, according to 3GPP TS 27.005, Annex A; backspace can be used to delete last character and carriage returns can be used; after every <CR> entered by the user the sequence <CR><LF><greather_than><space> is sent to the TE.
- if current <dcs> (see +CSMP ) indicates that 8-bit or UCS2 data coding scheme is used or current <fo> (see +CSMP ) indicates that 3GPP TS 23.040 TP-User-Data-
Header-Indication is set, the entered text should consist of two IRA character long hexadecimal numbers which ME/TA converts into 8-bit octet (e.g. the ‘asterisk’ will be entered as 2A ( IRA50 and IRA65 ) and this will be converted to an octet with integer value 0x2A )
Note: the DCD signal shall be in ON state while text is entered.
Note: the echoing of entered characters back from the TA is controlled by echo command E
To send the message issue Ctrl-Z char ( 0x1A hex).
To exit without sending the message issue ESC char ( 0x1B hex).
If message is successfully sent to the network, then the result is sent in the format:

#PORTCFG: <requested>,<active>
Test command reports a brief description of the supported ports arrangement solutions. For each <Variant> parameter value are displayed, on one row, the allowed couples formed by: a physical port and the logically connected internal software Access Point (AT, TT).
On each row are reported the couples concerning both configurations:
USB cable plugged into USB port or not plugged in.
AT, indicated on each command row result, can be AT0, AT1, or AT2.

Data Link - #DLINK
#DLINK – Data Link
AT#DLINK=<act>,<urc_mod e>
SELINT 2
Set command establishes or terminates data link channel between the Telit Mobile (USB5) and the first logic cmux channel DLCI_1.
Parameters:
<act> - Data Link Action
0 – Terminate Data Link Channel
1 – Establish Data Link Channel
<urc_mode> - URC mode
0 – Disable URC message about Data Link status
1 – Enable URC message about Data Link status
If <urc_mode>=1 , Data link status reported as followings
#DLINK: <status>
<status>
0 : Data Link disconnected
1 : Data Link connected
Note: this command required #PORTCFG=12 and #USBCFG=1 or
#USBCFG=2; both the settings should be configured before to issue
#DLINK.
Note: #DLINK connects the port where it has been issued with Telit
Mobile (USB5). By now this command can be issued only on DLCI_1
(first cmux logical data channel), so the cmux must be up & running.
Note: Once DLCI_1 is connected with DLINK-USB successfully,
DLCI_1 couldn’t accept AT commands any more. “+++” escape sequence character on DLCI_1 or Telit Mobile (USB5) will terminate the data link channel; sending AT#DLINK=0 on any other port will produce the same result.
Note: until the data link channel is not established the Telit Mobile
(USB5) port is internally disconnected, it cannot process any kind of data (e.g. AT commands).
Note: a typical configuration is
DLCI_1 connected to AT parser or Telit Mobile (USB5)

#TEMPMEAS: <level>,<value> where:
<level> and <value> are as before
<action> - sum of integers, each representing an action to be done whenever the module internal temperature reaches either operating or extreme levels
(default is 0). If <action> is not zero, it is mandatory to set the
<hyst_time> parameter too.
0..7 - as a sum of:
0 - no action
1 - automatic shut-down when the temperature is beyond the extreme bounds
2 - RF RX and TX circuits automatically disabled (using +CFUN=4 ) when operating temperature bounds are reached. When the temperature is back to normal the module is brought back to the previous state, before RF
RX and TX disabled.
4 - the output pin <GPIO> is tied HIGH when operating temperature bounds are reached; when the temperature is back to normal the output pin <GPIO> is tied LOW. If this <action> is required, it is mandatory to set the <GPIO> parameter too.
<hyst_time> - hysteresis time: all the actions happen only if the extreme or operating bounds are maintained at least for this period. This parameter is needed and required if <action> is not zero.
0..255 - time in seconds
<GPIO> - GPIO number. valid range is “any output pin” (see “Hardware User’s
Guide”). This parameter is needed and required only if <action>=4 is required.
Note: the URC presentation mode <urcmode> is related to the current AT instance only (see +cmux ); last <urcmode> settings are saved for every instance as extended profile parameters, thus it is possible to restore them either if the multiplexer control channel is released and set up, back and forth.
Note: in case that action 4 is set, the chosen GPIO has to be configured in alternate function ALT3 through AT#GPIO command

Set command enables/disables the automatic call function.
Parameter:
SELINT 2
<mode>
0 - disables the automatic call function (factory default)
1 - enables the automatic call function. If enabled (and &D2 has been issued), the transition OFF/ON of DTR causes an automatic call to the first number
(position 0) stored in the internal phonebook.
Note: type of call depends on the last issue of command +FCLASS .
AT#ACAL?
AT#ACAL=?
Note
Read command reports whether the automatic call function is currently enabled or not, in the format:
#ACAL: <mode>
Note: as a consequence of the introduction of the command #ACALEXT
(Extended Automatic Call) it is possible that the Read Command returns a value supported by #ACALEXT but NOT supported by #ACAL .

Set command enables/disables the extended automatic call function.
<mode>,<index>
Parameters:
<mode>
0 - disables the automatic call function (factory default)
1 - enables the automatic call function from internal phonebook.
2 - enables the automatic call function from “SM” phonebook.
<index> - it indicates a position in the currently selected phonebook.
If the extended automatic call function is enabled and &D2 has been issued, the transition OFF/ON of DTR causes an automatic call to the number stored in position <index> in the selected phonebook.
Note: type of call depends on the last issue of command +FCLASS .
AT#ACALEXT?
AT#ACALEXT=?
Note
Read command reports either whether the automatic call function is currently enabled or not, and the last <index> setting in the format:
#ACALEXT: <mode>,<index>
The range of available positions in a phonebook depends on the selected phonebook. This is the reason why the test command returns three ranges of values: the first for parameter <mode>, the second for parameter <index> when is chosen the internal phonebook, the third for parameter <index> when “SM” is the chosen phonebook.
Issuing #ACALEXT causes the #ACAL <mode> to be changed.
Issuing AT#ACAL=1 causes the #ACALEXT <index> to be set to default.
It is recommended to NOT use contemporaneously either #ACALEXT and
#ACAL

If not set explicitly, the module preserves the previous value
0 – Disable the buffer_size limitation (default)
28 – 16384 Resize the internal cmux output buffer to the selected value.
When a cmux session will be started using AT+CMUX, this value might be increased; if it is less than (N1 * 4), it becomes exactly N1 * 4. The current value can be gotten using the read command.
The cmux out buffer contains the frames ready to be sent for every DLCI.
If the modules receives an MSC indicating a RTS state to lock the data flow, these frames (already in the buffer) will be sent.
The default size of these buffer is about 32k.
Note: a software or hardware reset restores the default value.
Note: during a cmux session the set command will fail, only the read and test command can be used
Note: reducing the buffer_size will change the behaviour of cmux .
Several test have been performed using N1=122 at 115200bps => buffer_size = 488:
the bandwidth is decreased by 15%
the bandwidth is not equally distributed, the first channel has the max priority, then the second and the third
Note: if the module is downloading a lot of data and the application processor lock the flow moving the logical RTS (with MSC), the module can send more than buffer_size data

#SMSATRUN – Enable SMS AT Run service
Note1: When the service is active on a specific AT instance (see
SELINT 2
AT#SMSATRUNCFG), that instance cannot be used for any other scope, except for OTA service that has the highest priority.
For example in the multiplexer request to establish the Instance, the request will be rejected.
Note2: the current settings are stored in NVM.
AT#SMSATRUN? Read command returns the current settings of <mode> and the value of <stat> in the format:
AT#SMSATRUN =?
Notes:
# SMSATRUN: <mod>,<stat>
where:
<stat> - service status
0 – not active
1 - active
Test command returns the supported values for the SMSATRUN parameters
•
By default the SMS ATRUN service is disabled
It can be activated by the command AT#SMSATRUN.

<action_id>
Identifier of the action to trigger when the threshold limit has been reached. It corresponds to the AT command associated to the event
CONSUMEX, where X=1,…5. (Refer to #EVMONI command)
Range: (0-5); 0 means no action associated: in this case only the counter is active.
Note: the Set command #CONSUMECFG=0 has a special behaviour: for all the enabled rules, the data and time of related counters are reset (if they are not-life counters)
Note: the values set by command are directly stored in NVM and don’t depend on the specific AT instance
Note: the life counters are disabled if < enable > parameter of
AT#ENACONSUME is equal to 0
Note: a rule can be changed only setting <rule_enable> =0. The data and time of related counter are also reset (if it’s not a life counter).
Note: when the period expires, the counted data are reset, so the counting in the next period starts from 0.
Note: if a service is blocked, then the related (life or not) counter is stopped also in terms of time (as well as in terms of data obviously).
Read command returns the current settings for each rule in the format:

AT#SS[=<connId>] Execution command reports the current status of the socket:
Parameters:
<connId> - socket connection identifier
1..6
The response format is:
SELINT 2
#SS: <connId>,<state>,<locIP>,<locPort>,<remIP>,<remPort> where:
<connId> - socket connection identifier, as before
<state> - actual state of the socket:
0 - Socket Closed.
1 - Socket with an active data transfer connection.
2 - Socket suspended.
3 - Socket suspended with pending data.
4 - Socket listening.
5 - Socket with an incoming connection. Waiting for the user accept or shutdown command.
6 - Socket resolving DNS.
7 - Socket connecting.
<locIP> - IP address associated by the context activation to the socket.
<locPort> - two meanings:
the listening port if we put the socket in listen mode.
the local port for the connection if we use the socket to connect to a remote machine.
<remIP> - when we are connected to a remote machine this is the remote IP address.
<remPort> - it is the port we are connected to on the remote machine.
Note: issuing #SS<CR> causes getting information about status of all the sockets; the response format is:
#SS: <connId1>,<state1>,<locIP1>,<locPort1>,<remIP1>,<remPort1>
<CR><LF>

1 - new behaviour for transmission timer: restart when new data received from serial port
Note: is necessary to avoid overlapping of the two methods.
Enabling new method, the old method for transmission timer(#SCFG) is automatically disabled to avoid overlapping.
Note: check if new data have been received from serial port is done with a granularity that is directly related to #SCFG <txTo> setting with a maximum period of 1 sec.
<abortConnAttempt> Enable connection attempt(#SD/#SKTD) abort before CONNECT(online mode) or OK(command mode)
0 – Not possible to interrupt connection attempt
1 – It is possible to interrupt the connection attempt

any valid IP address in the format: “xxx.xxx.xxx.xxx”
any host name to be solved with a DNS query
<closureType> - socket closure behaviour for TCP when remote host has closed
0 - local host closes immediately (default)
255 - local host closes after an AT#SH or immediately in case of an abortive disconnect from remote.
<lPort> - UDP connections local port
1..65535
<connMode> - Connection mode
0 - online mode connection (default)
1 - command mode connection
Note: <closureType> parameter is valid for TCP connections only and has no effect (if used) for UDP connections.
Note: <lPort> parameter is valid for UDP connections only and has no effect (if used) for TCP connections.
Note: if we set <connMode> to online mode connection and the command is successful we enter in online data mode and we see the intermediate result code
CONNECT . After the CONNECT we can suspend the direct interface to the socket connection (nb the socket stays open) using the escape sequence ( +++ ): the module moves back to command mode and we receive the final result code OK after the suspension. After such a suspension, it’s possible to resume it in every moment (unless the socket inactivity timer timeouts, see #SCFG ) by using the
#SO command with the corresponding <connId> .
Note: if we set <connMode> to command mode connection and the command is successful, the socket is opened and we remain in command mode and we see the result code OK .
Note: if there are input data arrived through a connected socket and not yet read because the module entered command mode before reading them (after an escape

<cause> - socket disconnection cause:
0 – not available(socket has not yet been closed)
1.- remote host TCP connection close due to FIN/END: normal remote disconnection decided by the remote application
2 -.remote host TCP connection close due to RST, all others cases in which the socket is aborted without indication from peer (for instance because peer doesn't send ack after maximum number of retransmissions/peer is no more alive).
All these cases include all the "FATAL" errors after recv or send on the
TCP socket(named as different from EWOULDBLOCK)
3.- socket inactivity timeout
4.- network deactivation(PDP context deactivation from network)
Note: any time socket is re-opened, last disconnection cause is reset. Command report 0(not available).
Note: user closure cause( #SH ) is not considered and if a user closure is performed after remote disconnection, remote disconnection cause remains saved and is not overwritten.
Note: if more consecutive closure causes are received, the original disconnection cause is saved.
(For instance: if a TCP FIN is received from remote and later a TCP RST because we continue to send data,
FIN cause is saved and not overwritten)
Note: also in case of <closureType> ( #SD ) set to 255, if the socket has not yet been closed by user after the escape sequence,
#SLASTCLOSURE indicates remote disconnection cause if it has been received.
Note: in case of UDP, cause 2 indicates abnormal(local) disconnection. Cause 3 and 4 are still possible.
(Cause 1 is obviously never possible)
Note: in case of command mode connection and remote closure with subsequent inactivity timeout closure without retrieval of all available data(#SRECV or SRING mode 2), it is indicated cause 1 for both possible FIN and RST from remote.

SELINT 2
This command permits, while the module is in command mode, to send data over UDP to a specific remote host.
UDP connection has to be previously completed with a first remote host through #SLUDP / #SA .
Then, if we receive data from this or another host, we are able to send data to it.
Like command #SSEND , the device responds with ‘> ‘ and waits for the data to send.
Parameters:
<connId> - socket connection identifier
1..6
<remoteIP> - IP address of the remote host in dotted decimal notation, string type: “xxx.xxx.xxx.xxx”
<remotePort> - remote host port
1..65535
Note: after SRING that indicates incoming UDP data and issuing
#SRECV to receive data itself, through #SS is possible to check last remote host (IP/Port).
Note: if successive resume of the socket to online mode
Is performed( #SO ), connection with first remote host is restored as it was before.

SSL Commands
Open a socket SSL to a remote server - #SSLD
#SSLD – Opens a socket SSL to a remote server
AT#SSLD=<SSId>,
<rPort>,<IPAddress>,
<ClosureType>[,
<connMode>[,
<Timeout>]]
SELINT 2
Execution command opens a remote connection via socket secured through
SSL. Both command and online modes can be used.
In the first case ‘OK’ is printed on success, and data exchange can be performed by means of #SSLSEND and #SSLRECV commands.
In online mode ‘CONNECT’ message is printed, and data can be sent/received directly to/by the serial port. Communication can be suspended by issuing the escape sequence (by default +++) and restored with #SSLO command.
Parameters:
<SSId> - Secure Socket Identifier
1 - Until now SSL block manage only one socket
<rPort> - Remote TCP port to contact
1..65535
<IPAddress> - address of the remote host, string type. This parameter can be either:
any valid IP address in the format: “xxx.xxx.xxx.xxx” any host name to be solved with a DNS query
<ClosureType> -
0 – only value 0 supported
<connMode> - connection mode
0 – online mode connection.
1 – command mode connection (factory default).
<Timeout> - time-out in 100 ms units. It represents the maximum allowed
TCP inter-packet delay. It means that, when more data is expected during the handshake, the module awaits <Timeout> * 100 msecs for the next packet. If no more data can be read, the module gives up the handshake and raises an ERROR response.
Note: IT’S NOT the total handshake timeout or, in other words, it’s not the absolute maximum time between the #SSLD issue and the
CONNECT/OK/ERROR response. Though by changing this parameter you can limit the handshake duration (for example in case of congested network or busy server), there’s no way to be sure to get the command response within a certain amount of time, because it depends on the TCP connection time, the handshake time and the computation time (which depends on the authentication mode and on the size of keys and certificates).

10..5000 - hundreds of ms (factory default is 100)
Note: if secure socket is not enabled using AT#SSLEN only test requests can be made.
Note: if timeout is not set for SSL connection the default timeout value, set by
AT#SSLCFG, is used.
Note: in online mode the socket is closed after an inactivity period
(configurable with #SSLCFG, with a default value of 90 seconds), and the
‘NO CARRIER’ message is printed.
Note: in online mode data are transmitted as soon as the data packet size is reached or as after a transmission timeout. Both these parameters are configurable by using #SSLCFG.
Note: if there are input data arrived through a connected socket and not yet read because the module entered command mode before reading them (after an escape sequence or after #SSLD has been issued with <connMode> set to command mode connection), these data are buffered and we receive the
SSLSRING URC (if any of its presentation formats have been enabled by means the #SSLCFG command); it’s possible to read these data afterwards issuing #SSLRECV. Under the same hypotheses it’s possible to send data while in command mode issuing #SSLSEND.
Note: Before opening a SSL connection the GPRS context must have been activated by AT#SGACT=x,1.
Note: Before opening a SSL connection, make sure to have stored the needed secure data (CA certificate), using AT#SSLSECDATA.
Note: in case of CA Certificate already stored(for instance: SUPL), it could be possible to avoid #SSLSECDATA command.
Test command returns the range of supported values for all the parameters:
#SSLD: (1),(1-65535),,(0),(0,1),(10-5000)

SSLSRING: <SSId>,<recData> where <SSId> is the secure socket identifier and <recData> is the amount of data received and decoded by the SSL socket.
A new unsolicited is sent whenever the amount of data ready to be read changes. Only a record is decoded at once so, any further record is received and decoded only after the first have been read by the user by means of the #SSLRECV command.
2 – SSLSRING enabled in the format
SSLSRING: <SSId>,<dataLen>,<data> where <SSId> is the secure socket identifier, <dataLen> is the length of the current chunk of data (the minimum value between the available bytes and 1300) and <data> is data received (<dataLen> bytes) displayed in ASCII format.
<noCarrierMode> - this parameter permits to choose NO CARRIER indication format when the secure socket is closed as follows:
0 – NO CARRIER
(default)
Indication is sent as usual, without additional information
1 – NO CARRIER:SSL,<SSId>
Indication of current <SSId> secure socket connection is added. The fixed “SSL” string allows the user to distinguish secure sockets from
TCP sockets

SELINT 2
Set command sets the maximum time that the module awaits before sending
Parameter:
<tout> - packet sending time-out in 100ms units (factory default is 50)
0 - no time-out, wait forever for packets to be completed before send.

Note
SELINT 2
Execution command executes a DNS query to solve the host name into an IP address.
Parameter:
<host name> - host name, string type.
If the DNS query is successful then the IP address will be reported in the result code, as follows:
#QDNS: <host name>,<IP address> where
<host name> - string type
<IP address> - string type, in the format “xxx.xxx.xxx.xxx”
Note: the command has to activate the GPRS context if it was not previously activated. In this case the context is deactivated after the DNS query. It also works with GSM context, but the GSM context has to be activated before.
Test command returns the OK result code.
This command requires that the authentication parameters are correctly set and that the GPRS network is present (or GSM, if GSM context is used).
Issuing command #QDNS will overwrite <remote addr> setting for command
#SKTSET .
This command is available only on the first AT instance (see AT#PORTCFG) or on the first virtual port of CMUX and works on the PDP context 1 and on the first

Parameter:
<mode>
0 - caching disabled; it cleans the cache too
1 - caching enabled
Note: the validity period of each cached entry (i.e. how long a DNS response remains valid) is determined by a value called the Time To Live ( TTL ), set by the administrator of the DNS server handing out the response.
Note: If the cache is full (8 elements) and a new IP address is resolved, an element is deleted from the cache: the one that has not been used for the longest time.
Note: it is recommended to clean the cache, if command +CCLK has been issued while the DNS Response Caching was enabled.
AT#CACHEDNS? Read command reports whether the DNS Response Caching is currently enabled or not, in the format:
#CACHEDNS: <mode>

It is possible to restart the SAT session from the main menu again with the command AT#STGI=37 .
Note: The settings are saved on user profile and available on following reboot. SIM
Toolkit activation/deactivation is only performed at power on.

#STIA: <state>,<mode>,<timeout>,<SatProfile> where:
<state> - the device is in one of the following state:
0 - SIM has not started its application yet
1 - SIM has started its application (SAT main menu ready)
<mode> - SAT and unsolicited indications enabling status (see above)
<timeout> - time-out for user responses (see above)
<SatProfile> - SAT Terminal Profile according to GSM 11.14, i. e. the list of SIM
Application Toolkit facilities that are supported by the ME. The profile cannot be changed by the TA.
Note: In SAT applications usually an SMS message is sent to the network provider containing service requests, e.g. to send the latest news. The provider returns a message with the requested information.
Before activating SAT it is recommended to set the SMS text mode with command
AT+CMGF=1 and to enable unsolicited indications for incoming SMS messages with command +CNMI .
Test command returns the range of available values for the parameters <mode> and
<timeout> .
Just one instance at a time, the one which first issued AT#STIA=n (with n different from zero), is allowed to issue SAT commands, and this is valid till the same instance issues AT#STIA=0 .
After power cycle another instance can enable SAT.
A typical SAT session on AT interface starts after an #STN: 37 unsolicited code is received, if enabled(see above). At that point usually an AT#STGI=37 command is

#STN: 37 is an indication that the main menu of the SIM Application has been sent to the TA.
It will be stored by the TA so that it can be displayed later at any time by issuing an
AT#STGI=37 command.
A typical SAT session on AT interface starts after an #STN: 37 unsolicited code is received, if enabled. At that point usually an AT#STGI=37 command is issued, and after the SAT main menu has been displayed on TE an AT#STSR=37,0,x command is issued to select an item in the menu (see below). The session usually ends with a SIM action like sending an SMS, or starting a call. After this, to restart the session from the beginning going back to SAT main menu it is usually required an AT#STSR=37,16 command.

AT#ECHOCFG=<par_1>
[,<par_2>[,…,<par_N>]] active audio profile is 0.
SELINT 2
Set command writes values in echo reducer parameters. It is not allowed if
The module responds to the set command with the prompt '>' and waits for the data to send.
Parameters:
<par_1>
0 – configure all parameters, module awaits 39 values
1,2,..,39 – configure single parameters, module awaits 1 value
<par_i> with i = {2;N}
1,2,..,39 – configure every parameter specified
After '>' to complete the operation send Ctrl-Z char (0x1A hex); to exit without writing the message send ESC char (0x1B hex).
Data shall be written in Hexadecimal Form with 4 digits for every
<par_i> value provided by set command.
If data are successfully sent, then the response is OK.
If data sending fails for some reason, an error code is reported.
Parameters can be saved in NVM using AT#PSAV command and are available for audio profiles 1,2,3. For audio profile 0 the values are fixed.
Note: Configuring single parameters, it is allowed to enter a maximum of
32 parameters.
Note: the default configuration is targeted for almost all common acoustic echo scenarios; if further tuning is needed the customer can change by oneself only the following parameters:
<par_14>
0..32767 - factory default value is 18384
Additional gain: increasing this parameter average echoes are more attenuated
<par_15>
0..16384 - factory default value is 2000
Total gain lower limit: increasing this parameter small echoes are more attenuated
<par_16>

User Defined Tone SET - #UDTSET command
#UDTSET – User Defined Tone SET
AT#UDTSET=
<tone> Parameters:
SELINT 2
Set command sets frequency and amplitude composition for a User Defined Tone.
,<F1>,<A1>
[,<F2>,<A2>
<tone> - tone index (G,H,I,J,K,L)
<Fi> - frequency in Hz; range is (300,3000) in step of 1 Hz
[,<F3>,<A3>]] <Ai> - amplitude in dB; range is (10,100) in step of 1 dB
Note: Ai = 100 is equal to the max value of the single tone. Lower values attenuate output to the difference between 100 and the selected amplitude (ex: Ai = 80 is equal to 100-80 = -20dB).
Note: issuing AT&F1 or AT&Z has the effect to set the parameters with the last saved in NVM values
Note: Ai = 0 and Fi = 0 are only values for uninitialized parameters and can’t be issued by AT command. Every time the set command is issued, the unspecified parameters are automatically reset to zero.
(Ai,Fi) issuing needs also (Aj,Fj) with j<i.
AT# UDTSET?
AT# UDTSET =?
Read command returns the current settings for the tones:
#UDTSET: G,<F1>,<A1>,<F2>,<A2>,<F3>,<A3>

DTMFCFG – Embedded DTMF decoder configuration
AT#DTMFCFG=<scaling>
,<threshold_1>,<threshold_
2>[,<std_twist>,<rev_twist>]
SELINT 2
Set command allows configuration of the embedded DTMF decoder.
Parameters:
<scaling>:
3..11 – this is the scaling applied to the pcm samples in order to manage arithmetic operations. The default value is 7.
<threshold_1>:
1000..20000 – this is the numeric threshold used to detect DTMF tones. The default value is 2500.
<threshold_2>:
1000..20000 – this is the numeric threshold used to start DTMF decoding. The default value is 1500.
<std_twist>:
0..20 – standard twist threshold. It is an optional parameter and the default value is 9.
<rev_twist >:
0..20 – reverse twist threshold. It is an optional parameter and the default value is 5.
Note: The default values were chosen after a fine tuning, so every change should be done very carefully to avoid wrong decoding.
Note: the values set by command are not saved and a software or hardware reset restores the default value.
Note: Default values are referred to standard DMTF decoder
(AT#DTMF=1).
Note: It is supposed that the module is just powered on and the
AT#DTMFCFG command is entered without < std_twist> and
<rev_twist> parameters. In this case the read command doesn’t return the setting of the <std_twist> and <rev_twist> in order to meet retro compatibility with other families. Now, let’s assume that

#OTAIPUPD – Start an OTA Update over IP
AT#OTAIPUPD
AT#OTAIPUPD?
AT#OTAIPUPD =?
SELINT 2
This command starts an OTA Update over IP.
Note: in order to complete the update, the device has to be registered in the OTA server.
Note: it is necessary to set some parameters beforehand: the bearer (CSD or GPRS) and the APN, through the command AT#OTASNAPIPCFG, the
IP port and IP address, through the command AT#OTAIPCFG.
After the command AT#OTAIPUPD has been set, some unsolicited messages will inform the user about the status of the update process:
-
#OTAEV: Start Fw Download
-
#OTAEV: Fw Download Complete
-
#OTAEV: Module Upgraded To New FW
-
#OTAEV: Server notified about successfull
FW Upgrade
Or, in case of failure:
-
#OTAEV: OTA FW Upgrade Failed
Read command reports the current status of the OTA over IP: the value 1 is returned if the OTA over IP is running (in this case the user shall receive the unsolicited messages), 0 otherwise.
#OTAIPUPD: <status>
Test command tests for command existence
