1 Introduction

1.1 Scope of the document

This document presents the AT Command Set for Quectel cellular engine M10.

1.2 Conventions and abbreviations

In this document, the GSM engines are referred to as following term:
1) ME (Mobile Equipment);
2) MS (Mobile Station);
3) TA (Terminal Adapter);
4) DCE (Data Communication Equipment) or facsimile DCE(FAX modem, FAX board);
In application, controlling device controls the GSM engine by sending AT Command via its serial
interface. The controlling device at the other end of the serial line is referred to as following term:
1) TE (Terminal Equipment);
2) DTE (Data Terminal Equipment) or plainly "the application" which is running on an
embedded system;

1.3 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.
The AT Command set implemented by M10 is a combination of GSM07.05, GSM07.07 and
ITU-T recommendation V.25ter and the AT commands developed by Quectel.
Note: Only enter AT Command through serial port after M10 is power on and Unsolicited
Result Code "RDY" is received from serial port. If autobauding is enabled, the Unsolicited
Result Codes "RDY" and so on are not indicated when you start up the ME
All these AT commands can be split into three categories syntactically: "basic", "S parameter",
and "extended". These are as follows:

1.3.1 Basic syntax

These AT commands have the format of "AT<x><n>", or "AT&<x><n>", where "<x>"is the
Command, and "<n>"is/are the argument(s) for that Command. An example of this is "ATE<n>",
which tells the DCE whether received characters should be echoed back to the DTE according to
M10_ATC_V1.01 - 9 -
