Hi Team,

I have set the TX gain AT+QMIC=4500,200, we observe that voice gain is sufficient but it feel echo on the voice, I check the ECho cancellation command AT+QEEC=,, but I am not able to understand how to choose the index and value. and does that exact mean of index and value ?

Hi Shani,
index and value means the QEEC AT command optional, the picture may dispet your doubt
