[SL8084T][OPAT/AT Command] How to raise microphone gain

Hi,

Currently,I’m using analog audio by voice application then
I’d like to raise the microphone gain.

I think SL8084T can support only 0 or max(24dB) by AT+VGT and default is 24dB.

Is there any ways to raise microphone gain more from 24dB?

Thank you.

Hi,

i also tried to change the values…It seems we cannot change the values … i’ll update you once i’ll get some pointers on this… only 0 and 2400 is there…

topic moved to correct section…

Hi,

It seems to be the known behavior. We are working internally onthis and will be fixed in upcoming FW releases.

and how about it now?
