!AVRXAGC
Supporting chipsets (voice-
enabled devices only):
• MDM6200
• MSM6290 (min f/w rev:
K1_0_2_0ap)
• QSC6270 (min f/w rev: S2.0)
Set/report Rx AVC/AGC configuration
Set the Rx AVC/AGC (Automatic Volume Control/Automatic Gain Control)
configuration for the specified profile. The Rx AGC compensates for variations in
audio gains from the land line side, while the Rx AVC tracks the ambient audio noise
on the mobile side and compensates accordingly. Both controls allow for a constant
audio level in the Rx direction.
The setting is stored in non-volatile memory and persists across power cycles.
Device-specific details:
• MSM6290 (Firmware revisions K2_0_7_8ap and lower):
• The change takes effect the next time the modem restarts.
• All other chipsets/firmware revisions:
• The change takes effect immediately for the specified profile.
Usage:
• Execution: AT!AVRXAGC=<profile>, <value>
Response:
OK
Purpose: Set the Rx AVC/AGC configuration for the specified <profile>.
• Query: AT!AVRXAGC?<profile>
Response:
<value>
