3.5.5.1.32. Audio Profile Selection - #PSEL
#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>
