Note
The write command can be used during a voice call to switch back and forth bet-
ween different modes. This allows the user, for example, to switch handsfree
operation on and off.
Users should be aware that <outStep> is a global setting, i.e. when selecting an-
other audio mode the value of <outStep> does not change. This is also true for
mute operation which can be set with AT^SNFM or AT+CMUT: If the microphone
is muted and the user changes to another audio mode then the microphone re-
mains muted until explicitly changed. Exception: In audio mode 1 <outStep>=4 is
fix.
Example 1
Suppose a user wishes to use alternatively a handsfree device and a handset. The
handset can be connected to the first analog interface and adjusted to audio mode
4. The handsfree device can be attached to the second analog interface and ad-
justed to audio mode 2.
Settings for the handset:
at^snfs=4
OK
at^saic? Factory default of AT^SAIC assigned to audio mode 4.
^SAIC: 2,1,1
Settings for the handsfree device:
at^snfs=2
OK
at^saic?
^SAIC: 2,2,2 Factory default of AT^SAIC assigned to audio mode 2.
To store the configuration to the user defined audio profile:
at^snfw Stores the audio mode and the interface.
OK
To switch back and forth:
at^snfs=4 Switches to the handset connected to analog interface 1.
OK
at^snfs=2 Switches to the handsfree device at analog interface 2.
Example 2 The following example illustrates a combination of a handset and a handsfree de-
vice connected to other interfaces than those assumed as factory default.
Settings for a handset connected to the second analog interface and adjusted to
audio mode 4:
at^snfs=4
OK
at^saic=2,2,2
Settings for a handsfree device connected to the first analog interface and ad-
justed to audio mode 2:
at^snfs=2
ok
at^saic=2,1,1
OK
To store the configuration to the user defined audio profile:
