CC2564: A3DP profile for multi-BT-Mic phone

Gavin Jiang

Part Number: CC2564

Dears,

As I remembered, CC2564 A3DP profile can be used for multi-speaker application. Could you please tell me is it possible to use 2 pcs (or more, say 3pcs) CC2564 for a multi-BT-Mic conference phone?

And how to build it up by using 2 kits of BT-MSPAUDSOURCE EVMs? thanks!

The block diagram as below, note that, the 2 Mic should work simultaneous.

Hello Gavin,

Unfortunately this won't be possible.
The multi-Speaker solution takes one stream and sends it simultaneously to several speakers playing it at the same time.

What you are suggesting here if i understand you correctly is to have multiple inputs coming from several pcs.
each microphone will generate a stream on input and all of them will be shared.

Supporting several input streams isn't an option using this feature.

BR,
Chen Loewy
