Are you asking for a shared SDIO bus for WiFi data & BT audio? Why is this required?

Keeping a shared SDIO bus would affect the Throughput of WiFi. There would significant wastage of bandwidth of SDIO considering bluetooth data rates are limited to just around 20Mbps. Besides currently, there is no driver support for BT through SDIO.

Dear Vinayak:

     Thanks for your answer.

     We want shared SDIO for wifi data & BT AUDIO to decrease connection.

     As your suggestion,we will not choice this solution to ensure  the SDIO bus throughput.

Thanks!
