Is it possible to run 2 concurrent HFP audio streams on the CC2564?

Hi,

Yes as mentioned in the datasheet.

Hi,

I couldn't find this information in the datasheet. Can you point me to it?

Is it possible to have 4 instances of the HFP and MAP profiles at the same time?

Thanks,

DJ,

You could run multiple instances at the BT stack profile level if you have enough memory. For the HFP, only two concurrent SCO links are supported.

Hi Miguel,

Are the SCO/eSCO links independent to the HFP implementation, or are they directly tied to it? My customer could support multiple HFP if they do not each require an SCO/eSCo link.

Thanks,

DJ,

The SCO/eSCO links are established when a voice connection is active. Otherwise, they don't exist. So they are related to the HFP implementation.

Hi Miguel,

Sorry about this but that doesn't quite clarify what I'm after.

Can you have 4 active HFP connections if there is only 1 voice connection (SCO)?

Thanks,

DJ,

We have tested 2 HFP connections (CC256XSTBTBLESW --> HFPDemo) only, but your scenario should work. Note that there will be limitations on the responsiveness when having the eSCO/SCO connection up given the slots available between SCO packets. There won't be many slots available for serving the 4 HFP control/data packets. Also, the CC256x must be the Master for all the connections.

Regards,
Miguel

Thanks Miguel.

What SCO packet types are supported? Can HV3 be used?

Thanks,

DJ,

Yes, we support the SCO and eSCO configuration parameters defined by the HFP 1.6 specs. You may refer to section 5.7.3 and 5.7.4 in the HFP 1.6 specs.
