Hi,
I am working on setting speaker and mic for our application. I am using M66 modem.
I have implemented a calling feature which both loudspeaker and mic use same audio channel (channel 2).
When the call is in progress, other party listens echo of his own voice. I tried below settings using AT+QAPS. No change in the echo issue. Could anyone suggest the best settings to have 0% echo.
Best Regards,
Ankush
