AT Commands Features

2.1

Wavecom Line Settings

A serial link handler is set with the following default values (factory settings):

• speed according to customer choice at order time,
• 8 bits data,
• 1 stop bit,
• no parity,
• RTS/CTS flow control.

Please use the +IPR, +IFC and +ICF commands to change these settings.

2.2

Command Line

Commands always start with AT and finish with a <CR> character, excepted A/
command.

2.3

Information Responses and Result Codes

Responses start and end with <CR><LF>, except for the ATV0 DCE response format

and the ATQ1 (result code suppression) commands.

• If command syntax is incorrect, the "ERROR" string is returned.
• If command syntax is correct but transmitted with wrong parameters, the

"+CME ERROR: <Err>" or "+CMS ERROR: <SmsErr>" strings is returned with

adequate error codes if CMEE was previously set to 1. By default, CMEE is set

to 0, and the error message is only "ERROR".

• If the command line has been executed successfully, an "OK" string is returned.

In some cases, such as "AT+CPIN?" or (unsolicited) incoming events, the product does
not return the "OK" string as a response.

In the following examples <CR> and <CR><LF> are intentionally omitted.

2.4

Proprietary Commands

When a command is Wavecom proprietary, the information is indicated in the
command description.
