For example:
1 - Let's assume that the desired audio path is always the internal MT

Command:
AT#CAP=2<cr>
Answer:
OK


2 - Let's assume that the desired audio path has to be determined by HARDWARE pin AXE

Command:
AT#CAP=0<cr>
Answer:
OK

Now set the hardware pin AXE in the desired status.

2.6.1.3 Set the desired volume on the active audio path speaker output

This setting is not strictly necessary; it is also possible to keep the default volume setting.

• Send command

AT+CLVL=<vol><cr>

where:
<vol> is a number between 0 and 10 representing the volume setting:

0 – minimum volume

10 - maximum volume

• wait

for

OK

response

NOTE: The volume setting refers to the ACTIVE path ear line and is stored each time. When
changing audio path the volume setting will be reset to the previously stored value for that
audio path.

2.6.1.4 Check for microphone mute setting

The microphone of the active path can be muted with an AT command; to be sure that it is not muted,
it is suggested to check it with this command:
• Send command

AT+CMUT?<cr>

wait for response in the format:

+CMUT: <mute>

OK

where:
<mute> is the muting setting for the microphone:

0 - microphone active
