Hello

I think 96kHz_16bit Stereo Or When receiving 88.2kHz_16bit Stereo with I2S slave It is not necessary to specify them on WICED, and Sampling Frequency on WICED.
48kHz Or 44.1kHz and Is it okay to understand that the data received by the private internal logic is DownSampled just by specifying it?

 

Thanks,

Hi MiSa

It is necessary to set the I2S Slave and A2DP sampling frequency as usual
(similar to the case without downsampling),
but the downsampling process itself is performed inside CYW20706, so be especially careful.

 

Thanks
