Q2687,about the Audio Loop problem!


#1

I’m doing a porject that need Audio Loop,and it’s work well in Q24plus.I can hear my voice in the test.
But when I made audio loop in Q2687,The Audio Loop doesn’t work!!!

and I found that :Audio loop mode must not be enabled when a communication is active. in AT_Command_Interface_Guide.pdf

Is it means that when I make a phone call,I can’t do the audio Loop anymore?

what’s wrong?

Any help would be appreciated!

Thank you!
