•
For details, see "Tone settings for AT!AVTONEPLAY command"
page 110.
Set the TX AGC
This command sets the TX AGC (Automatic Gain Control) for the
specified profile. The TX AGC compensates for variations in audio gains
from the mobile side to allow for a constant audio level in the TX
direction.
The setting is stored in non-volatile memory and persists across power
cycles.
Module-specific details:
•
MC8775V — The change to the audio system takes place immedi-
ately if the specified audio profile is active.
•
MC8785V / MC8790V / MC8791V / MC8792V — The change to the
audio system takes place the next time the sound device (re)starts.
Usage:
•
AT!AVTXAGC=<profile>, <value> sets the TX AGC for the specified
profile.
•
AT!AVTXAGC?<profile> returns the current TX AGC (<value>) for
the specified profile.
