Customer is using the CYW20719B2.  The device will be used as an A2DP source, like the Watch app, but the audio to send over the air will be sourced from an I2S source.  The Device Configurator under MTB 1.1 will not allow the assignment of the I2S signals to pins.

How can this be configured?

Hi Corey,

Seems like this is a bug in MTB 1.1 BTSDK 1.4.

It will be fixed in MTB 2.0

I am checking internally with our software team for updates.

Thanks & Regards,

Anjana

Meanwhile please use API in APPLICATION_START of watch example. For example:

wiced_hal_gpio_select_function(WICED_Pxx,WICED_PCM_CLK_I2S_CLK);

wiced_hal_gpio_select_function(WICED_Pxx,WICED_PCM_OUT_I2S_DO);

wiced_hal_gpio_select_function(WICED_Pxx,WICED_PCM_IN_I2S_DI);

wiced_hal_gpio_select_function(WICED_Pxx,WICED_PCM_SYNC_I2S_WS);

Thanks,

Anjana
