CC2564C: Whether the CVSD data passed to application via UART/hci based on HFP is the PCM format data?

It would be CVSD data, if you are not using the decoder on the controller.. If, you seeing something let me know, i will recheck in the FW..

Thanks

I am not sure whether the decoder is using on the controller or not.

I want to know whether the decoder is activated on the CVSD data sending via UART way by default? It seems not activated accroding to your description, Does it?

And if to use decoder on the cotroller, Is there any method to do that, by sending verdonr-specific command? I don't see similiar HCI command?

Cloud you help share some advices?

Thanks very much.

Hello, 

If current HFP CVSD data transported via UART/HCI to application, when application received such audio data whether such data is raw pcm format to usd to play directly or still  need a CVSD-like decoder to decode to raw pcm data?

I  suggest you to take a look at either CC2564C STM or MSP432 Bluetopia SDK and check the HFP demo. The HFP demo configures the controller to use CVSD, mSBC codecs and route speech data through I2S/PCM lines.

Thanks
