Test command returns the
OK
result code.
Example
AT#PSAV
OK
Current audio profile is saved in NVM
#PSEL - Audio Profile Selection
AT#PSEL=<prof>
Set command selects the active audio profile
Parameter:
<prof>
: current profile
0 - standard profile
1..3 - extended profile, modifiable.
Note: This parameter is saved in NVM issuing AT&W command
.
AT#PSEL?
The read command returns the active profile in the format:
#PSEL:<prof>
AT#PSEL=?
Test command returns the supported range of values of parameter
<prof>
