ATA - Answer a call

The GSM module does not automatically answer calls after you switch on your com- puter. In accordance with the factory configuration, it does not go off-hook. The ATA command causes your GSM module to go off-hook when the phone rings. You deter- mine whether or not you wish to answer.

ATS0=n - Auto-answer mode

The ATS0=n command allows you to configure your GSM module so that it will auto- matically answer calls. "n" represents the number of ringing signals before the call is answered. Permissible values are from "0" to "5".

 

ATS0=n

[n=0..5]

 

 

 

Option

Result

 

 

 

 

ATS0=0

No auto-answer: incoming calls are ignored.

 

 

 

 

ATS0=1

The GSM module goes off-hook after the first ringing signal.

 

 

 

 

...

etc.

 

 

 

 

ATS0=5

The GSM module goes off-hook after the fifth ringing signal.

 

 

 

 

You can use the ATA command to answer calls at any time, regardless of these set- tings.

Displaying and storing a configuration

The GSM module works with a set of parameters that determine its functioning. This set of parameters is called the active configuration profile. Values for these parameters are predefined in a factory configuration that you can use at any time when you load it using the AT&F command. The GSM Module M1 allows you to modify the active con- figuration profile by means of AT or S-register commands. These options will be de- scribed in subsequent sections. When you switch off the GSM module, any changes you made to the active configuration profile are lost. When you switch it on again, the active configuration profile once again corresponds to the factory configuration. How- ever, the GSM module has two nonvolatile memory blocks in which you can store con- figuration profiles (AT&Wn command, page 29). These blocks are user profiles "0" and "1". When you switch on your system, the GSM module loads the user profile that you set by means of the AT&Yn command. For more information, see the section entitled “AT&Yn - Configuration at power-up”.

Please note:

When the module is supplied, both user memories contain the factory profile.
