Hi,
I am using M66 to generate voice calls. I am using loudspeaker speaker and loudspeaker mic. I am really not sure why the disturbance is coming once I recieve the call.
Speaker works fine with minimal disturbance. But when I speak on the mic, other party (mobile phone) gets lots of disturbance.
Could this be issue from Modem? or should I have to send any specfic AT commands to eliminate the disturbance.
Could anyone let me know please if you have come accross similar issue?
Best Regards,
Ankush
Hi Ankush
Welcome to Quectel Forum. Thanks for your query.
please use AT+QMIC command to set gain level of the mic. Also Set the audio channel to the loudspeaker with AT+QAUDCH=2.
yes. I am already performing these steps. The AT commands sent are
AT+QMIC=2,15
AT+QAUDCH=2
The disturbance is like when you are on call and you keep the phone next to any speaker, you get some sound. The same sound is coming for me continuousely
