CC2564: [A3DP Multiroom + SPP] Noise occurs when inquiry.

Part Number: CC2564

Hi,

I combined A3DP Multiroom Demo & SPPDemo.

I connected A2DP stream between Phone and Server SPK and execute Inquiry() in Server SPK to find Client SPK.

( Phone(Source) / Server SPK(Sink) / Client SPK )

If the inquiry is executed while music is being streamed, noise will occur until the inquiry process is finished.

However, it seems to occur not only during the inquiry command but also during the SPP connection process.

Why does noise occur?

Does the Inquiry command or SPP connection process are break with a lot of resources?

Or is it a confusing radio on the board?

    This is most likely the case. Please refer to this old thread regarding the limitations of the A3DP multiroom when combined with other profiles.

    Are you required to have multiple A3DP sink in this scenario? If not, you can just use the A3DP_SNK and A3DP_SRC (non-multiroom) demos to stream audio from one device to another. That would put less constraints on the bandwidth and other resources of the BT link and you may not notice such issues.

    Best regards,
