Execution command resets the actual audio parameters in the NVM of the device to
the default set. It is not allowed if active audio profile is 0.
The audio parameters to reset are:
- microphone line gain
- earpiece line gain
- side tone gain
- LMS adaptation speed (step size)
- LMS filter length (number of coefficients)
- speaker to micro signal power relation
- noise reduction max attenuation
- noise reduction weighting factor (band 300-500Hz)
- noise reduction weighting factor (band 500-4000Hz)
- AGC Additional attenuation
- AGC minimal attenuation
- AGC maximal attenuation
AT#PRST=?
Test command returns the
OK
result code.
Example
AT#PRST
OK
