[CYW920706] How to generate Local Tone via I2S

[Romeo]

Dear Cypress

I want to know if there is a way to play the tone through I2S.

As an example, when a user presses a button, I want to output pre-defined wav data to I2S. 

Please refer to below for detailed conditions:

   - H/W : CYW920706WCDEVAL

   - S/W : It doesn't matter if it is WICED or MODUS

Thanks in advance.

Hi,

I do not see a direct implementation of your required application. Since it is a bluetooth chip, the applications are more focussed on the bluetooth functionality.

A similar implementation you will be able to see in the below application where the SCO packets routed to PCM/I2S.

In the below application, the .wav file is transmitted from the ClientControl to the BT chip via UART.
