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.
3.5.5.1.34. 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>.
3.5.5.1.35. Handsfree Noise Reduction - #SHFNR
# SHFNR - Handsfree Noise Reduction
AT#SHFNR =
<mode>
Set command enables/disables the noise reduction function on audio handsfree
input.
Parameter:
<mode>
0 - disables noise reduction for handsfree mode (default)
1 - enables noise reduction for handsfree mode
Note: This parameter is saved in NVM issuing AT&W command.
AT#SHFNR?
Read command reports whether the noise reduction function on audio
handsfree input is currently enabled or not, in the format:
