Developers Guideline AT Commands

Preface

The Developers Guidelines for AT Commands Online Reference is designed to give the reader a deeper

insight into how to design applications with AT commands supported by mobile phones. The information

here is not relevant for the day-to-day operation of the phone. This is described in the User Guide supplied

with the mobile phone.

This document is for advanced users who require detailed information in order to:

• Develop new communications software

• Add the mobile phone to an application’s list of compatible modems

• Adjust the settings of their mobile phones

This document is based on general AT Commands information. However, specific information for mobile

phones is found in the appendixes.

People who can benefit from this document include:

• Application providers

• Content providers

• Content aggregators

• Operators and service providers

• Software developers

• Business decision-makers

It is assumed that the reader has a basic understanding of AT Commands. More information is available at

Sony Ericsson Developer World website at http://www.sonyericsson.com/developer

where up to date information about technologies, products and tools can be obtained.
