This document describes standard and proprietary AT commands available for UMTS mobile broadband devices
and intelligent embedded modules. Standard AT Commands are covered in Part 1 of this document. Proprietary
AT commands are supplemental to the standard AT commands and are covered in Part 2 of this document.
Standard 3GPP AT commands for UMTS devices are described in the following 3GPP (3rd Generation
Partnership Project) standards documents:
Some standard 3GPP commands are NOT supported, or are partially supported. These commands are identified
in the
Escape Sequence Guard Time
The AT escape sequence “+++” requires a guard time of 1.0 seconds before and after it is used.
Result Codes
Result codes are not shown in the command tables unless special conditions apply. Generally, the result code
OK is returned when the command has been executed. ERROR may be returned if parameters are out of range
and will be returned if the command is not recognized or is not permitted in the current state or condition of the
modem.
Conventions
High Speed HSPA-H4 AT Commands Reference Guide (Document S000483A)
The following format conventions are used in this reference:
Character codes or keystrokes that are described with words or standard abbreviations are shown within
angle brackets using a different font, such as <CR> for Carriage Return and <space> for a blank space
character.
Numeric values are decimal unless prefixed as noted below.
Hexadecimal values are shown with a prefix of 0x, i.e. in the form 0x3D.
Binary values are shown with a prefix of 0b, i.e. in the form 0b00111101.
Command and register syntax is noted using an alternate font: !CHAN=<c>[,b]. The “AT” characters are not
shown but must be included before all commands except as noted in the reference tables.
Characters that are required are shown in uppercase; parameters are noted in lowercase. Required
parameters are enclosed in angle brackets (<n>) while optional parameters are enclosed within square
brackets ([x]). The brackets are not to be included in the command string.
Commands are presented in table format. Each chapter covers the commands related to that subject and
presents a summary table to help you locate a needed command. Commands are in ASCII alphabetical
order in the body of each chapter.
Any default settings are noted in the command tables. Note that these are the factory default settings and not
the default parameter value assumed if no parameter is specified.
