Bluetooth audio sink AND source?

Paul DeMarco

Hello!

There is a reference design that shows how to implement an audio sink (speaker) using the CC256x, and in the future there will be a reference design showing an audio source (microphone).

My question is, is it possible to implement both an audio player and microphone using the CC256x?

What other components might it require?

What would be required if I'd like to play and record at the same time?

Thank you,

Paul

Hi Paul,

Could you please let me know what is the use case you are looking for.

Hi Sundeep,

The use case would be similar to a cell phone that is in speakerphone mode.

Use case:

I would have a main host PC which communicates to a wireless device utilizing CC256x.

The wireless device will have both a speaker and a microphone.

I would like the device to play the bluetooth audio as well as send back microphone audio, sometimes occurring simultaneously.

Hi,

I did not get you, what do you mean by routing audio to Microphone?

Do you want to send the audio data received to another CC256x Device?

There is only one wireless device. I would like it to play the audio recieved from PC and also send back microphone audio to PC.

Hi,

I am confused. You want to route the audio played on PC to CC256x and route the same audio played on PC to PC from CC256x, using A2DP?

I am guessing that you are connected to IP-phone(on your PC) and you wanted to route that audio to CC256x speakers and the If you talk from the micro phone this audio should be routed back to PC - this looks more like you wanted a HFP profile. If this is what you are looking for there should not be any problem in implementing it using CC256x.
