1.4 Document Conventions
Throughout this document EHS6 is also referred to as GSM/UMTS Mobile Engine or short ME, MS (Mobile Sta-
tion) or Mobile Terminal (MT). In related documents the equivalent term DCE (Data Communication Equipment)
may be found. 
AT commands are used to control the EHS6. The controlling device is referred to as Customer Application or
short TE. Related documents may use the equivalent term DTE (Data Terminal Equipment). 
All abbreviations and acronyms used throughout this document are based on 3GPP specifications. For defini-
tions please refer to 3GPP TR 21.905 [12].
1.4.1 Quick Reference Table
Each AT command description includes a table similar to the example shown below. The table is intended as a
quick reference to indicate the following functions: 

Example:
PIN: Is the AT command PIN protected?
+Yes
-No
±Usage is dependent on conditions specified for the command, or not all command types are PIN
protected (for example write command PIN protected, read command not).
Note: The table provided in Section 21.2, Available AT Commands and Dependency on SIM
PIN uses the same symbols.
Is the AT command supported in AIRPLANE mode?
+Yes
-No
±In AIRPLANE mode, not all described functions are available. For example, the test or read com-
mand is usable, the write or execute command is not. Furthermore, only some of the listed
parameters can be changed in AIRPLANE mode. A typical example is AT^SCFG that controls dif-
ferent features.
Last: If commands are concatenated, this AT command must be the last one.
+Yes
-No
Note: See also Section 1.5, AT Command Syntax for details on concatenated AT commands.

double quotes
<param>(u) Unspecified, i.e. parameter value may be numeric or string type.

AT+CSCS for details)
<param>(&W) Parameter value is stored to user profile in non-volatile memory after executing
AT&W
<param>(NV) Parameter is stored in non-volatile memory.
Value option Meaning
[x] Default value set if parameter is omitted.
x(&F) Factory value restored by AT&F
x(P) Powerup value of a parameter not stored in non-volatile memory.
x(D) Delivery value of a parameter which may be overridden from non-volatile setting
(refer to symbol (NV) and symbol (&W) above).

1.5 AT Command Syntax
The "AT" or "at" prefix must be set at the beginning of each command line. To terminate a command line enter
<CR>. Commands are usually followed by a response that includes "<CR><LF><response><CR><LF>".
Throughout this document, only the responses are presented, <CR><LF> are omitted intentionally.
Table 1.4: Types of AT commands and responses
1.5.1 Using Parameters
• Multiple parameters are separated by commas. This applies to write commands, command responses, URCs
and result codes. Please note that throughout this document spaces behind commas may be added for better
readability.
• Optional parameters are enclosed in square brackets. If optional parameters are omitted, the current settings
are used until you change them.
• Optional parameters or subparameters can be omitted unless they are followed by other parameters. If you
want to omit a parameter in the middle of a string it must be replaced by a comma. See also example 1.
• A parameter value enclosed in square brackets represents the value that will be used if an optional parameter
is omitted.
• When the parameter is a character string, e.g. <text> or <number>, the string must be enclosed in quotation
marks, e.g. "Charlie Brown" or "+49030xxxx". Symbols in quotation marks will be recognized as strings.
• All spaces will be ignored when using strings without quotation marks.
• It is possible to omit the leading zeros of strings which represent numbers.
• If an optional parameter of a ITU-T V.250 command is omitted, its value is assumed to be 0.

Example 1: Omitting parameters in the middle of a string
Example 2: Using default parameter values for optional parameters
AT command type Syntax Function
Test command AT+CXXX=? The mobile equipment returns the list of parameters and value
ranges set with the corresponding Write command or by internal
processes.
Read command AT+CXXX? This command returns the currently set value of the parameter or
parameters.
Write command AT+CXXX=<...> This command sets user-definable parameter values.
Exec(ution) command AT+CXXX The execution command reads non-variable parameters deter-
mined by internal processes in the ME.
AT+CCUG ? Query current setting
+CCUG: 1,10,1
OK
AT+CCUG =,9 Set only the middle parameter
OK
AT+CCUG ? Query new setting
+CCUG: 1,9,1
OK
AT+CREG = Setting default values for AT+CREG.
OK
AT+CREG ? Query settings.
+CREG: 0,0 AT+CREG default values are set.
OK

1.5.2 Concatenating AT Commands
Concatenating AT commands on the same line is possible, though not recommended because of restrictions
listed below (for more details see ITU-T V.250 [16]).
When concatenating AT commands you need to enter the "AT" or "at" prefix only once at the beginning of a com-
mand line. Basic commands (i.e., ITU-T V.250 commands) are concatenated without delimiter. Extended com-
mands (i.e., commands starting with AT+ or AT^) use a semicolon as delimiter.

Disadvantages and restrictions:
• There is no way to control the minimum time to wait between finishing an AT command and sending the next
one. Please refer to Section 1.6, Communication between Customer Application and EHS6 for details about
timing.
• The sequence of processing the AT commands may be different from the sequential order of command input.
• Many AT commands cannot be concatenated (see list below). Concatenating these commands might end up
with an error result code, or leads to an unexpected order of responses.
1.5.3 Application Design Considerations
When designing your application keep in mind that parameters given in AT command responses, result codes
and unsolicited result codes are only separated by commas with no spaces in between. Please take care that
your application ignores any additional spaces that may, nevertheless, be inserted in some AT command
responses, result codes and unsolicited result codes provided by EHS6.
