Notes
• The write command can be used during a voice call to switch back and forth between different modes. This
allows the user, for example, to switch handsfree operation (speakerphone) on and off.
• Users should be aware that
is a global setting. This means, when another audio mode is selected
does not change. This is also true for mute operation which can be set
with
: If the microphone is muted and the user selects another audio mode during the
call, then the microphone remains muted until explicitly changed. Exception: In audio mode 1
=4
is fix.
• For use after restart of the module, you are advised to store the selected mode to the audio profile saved with
. Otherwise, audio mode 1 will be active each time the module is powered up.
