1 Introduction

to the User’s Guide Command Manual

1.1 Overview

AT commands are used for communication between the CM52 module and an application. All the AT
commands that are supported by CM52 are described in this AT command manual.

The CM52 Integrator’s manual, which is provided with the CM52 module, contains information on the CM52
hardware, mechanics, Developer’s Kit and how to get started in general.

This manual assumes that the CM52 module is connected properly as defined in the Integrator’s manual and
is ready to start AT command communication.

1.2

How to read the manual

This manual is divided into five chapters.

Chapter 1

provides a general overview of the AT command manual. This chapter contains abbreviations used

throughout the AT command manual and also contains information concerning Service and Support.

Chapter 2

is a brief overview of the CM52 module. Detailed information about CM52 and the Developer’s kit

can be found in the CM52 Integrator’s Manual.

Chapter 3

describes the main functions and capabilities of the CM52 module.

Chapter 4

contains all of the AT commands that are supported by the CM52 module. Each AT command has

a description of its function and of its parameters. Examples are provided for some of the commands. In
addition to the descriptions of each AT command, the chapter begins with a description on how to use AT
commands in general.

Chapter 5

provides additional information about how to use the AT commands. This chapter contains user

scenarios for a variety of features.

Chapter 6

provides descriptions and examples on how to use many of the features that are supported by the

CM52.

Examples are provided throughout this manual to clarify the text descriptions. All AT command examples are
written in

Courier

font. To differentiate AT commands from the host controller and responses from the CM52

module, the responses are written in gray color.
