AT#PSET?
Read command returns the parameters for the active profile in the format:
#PSET:<scal_in>,<scal_out>,<side_tone_atten>,<adaption_speed>,
<filter_length>,<rxtxrelation>,<nr_atten>,<nr_w_0>,<nr_w_1>,
<add_atten>,<min_atten>,<max_atten>
It is not allowed if active audio profile is 0.
AT#PSET=? Test command returns the supported range of values for the audio
parameters.
3.5.7.1.56 Handsfree Automatic Gain Control - #SHFAGC
#SHFAGC - Handsfree Automatic Gain Control
AT# SHFAGC =
<mode>
Set command enables/disables the automatic gain control function on audio
handsfree input.
Parameter:
<mode>
0 - disables automatic gain control for handsfree mode (default)
1 - enables automatic gain control for handsfree mode
Note: This parameter is saved in NVM issuing AT&W command.
AT# SHFAGC? Read command reports whether the automatic gain control function on
audio handsfree input is currently enabled or not, in the format:
#SHFAGC: <mode>
AT# SHFAGC =? Test command returns the supported range of values of parameter
<mode>.
