Hi Shannon

If you want to use HFP and HSP, you need to feed voice to audio codec

like sabresd WM8962. Then through WM8962 rtl8723bs can get this pcm stream.

On sabresd board there is no such path for audio codec (need more pcm rx/tx pin),

so only way was to connect AR6233 using UART to processor. For these reasons

there is no way to support HSP and HSP on sabresd. This is meaning of

"Handset & Handfree(not support for hardware restrict)" mentioned on

How to enable BT on board imx6q_sabresd RevC. .

Best regards

Hi Shannon

seems this is because Handset & Handfree profiles are not supported

(due to MX6 SabreSD hardware restrict as described below)

Hi igorpadykov,

We use bt is rtl8723bs. It support HSP/HFP. And What do we need to modify can let HSP and HFP work normally?

Best regards

igorpadykov · ‎06-24-2015

Hi Shannon

If you want to use HFP and HSP, you need to feed voice to audio codec

like sabresd WM8962. Then through WM8962 rtl8723bs can get this pcm stream.

On sabresd board there is no such path for audio codec (need more pcm rx/tx pin),

so only way was to connect AR6233 using UART to processor. For these reasons

there is no way to support HSP and HSP on sabresd. This is meaning of

"Handset & Handfree(not support for hardware restrict)" mentioned on

How to enable BT on board imx6q_sabresd RevC. .

Best regards
