WL1831MOD: WL1831MOD BT stacks for BT Audio streaming

Part Number: WL1831MOD

Hi,

I would like to enquire on the general BT profile with regards to WiLink modules for BT audio streaming purpose. In current end product we are having HSP and HFP for BT with 8KHz sampling rate. If the intention is to use 16KHz for the BT I2S/PCM, will this module carry resample feature to down sample the 16khz audio to 8khz for HSP/HFP profile with 8khz sampling rate?

Regards,

Leo

HFP1.6 with mSBC wideband codec with 16KHz sample rate is supported. If, you are looking for it. Are are looking for assisted HFP with 8KHz CVSD, with just the I2S interface upsampled to 16KHz? As such this is not supported.. But, i wonder why do you need to just upsample the I2S interface..
