Other Parts Discussed in Thread: CC2564, TLV320AIC3256

Hi All,

I wanted to design a device which will connect with the smartphone via Bluetooth interface and will act as audio streaming module for the phone as well as that device will have mic input and also it will act as a hands free.

I am intending to use cc2564 for Bluetooth interface as it is dual mode module and supports required profiles.but as i am new to audio domain i don't know how to integrate mic and speaker. So i want suggestion from your side.I have refereed following two applications from ti,

www.ti.com/.../BT-MSPAUDSINK-RD

www.ti.com/.../BT-MSPAUDSOURCE-RD

do i need to merge this two products to have both mic and speaker interface? What i understand is one example is for SNK and one for SRC? Sorry if i am wrong,Just trying to understand the concepts.

Need your help.

Thanks in advance!Waiting for your reply.

    Hi, Vidula,

    I think your approach is correct, the integration of both modules can be used as reference. Maybe you can use a different codec for the audio signal streaming, like the TLV320AIC3256, this versatile device has several configuration options, analog inputs for microphone or line signals and analog outputs if you want to use a different amplifier for your system.
