Hello,

I've created my BT application based on the example hci_audio_gateway. The difference from the example is PCM audio which I trying to use but it doesn't work.

I configure PCM audio after start BT stack:

    wiced_hal_pcm_config_t pcmConfig;

    memset(&pcmConfig, 0, sizeof(pcmConfig));

    pcmConfig.mode = WICED_HAL_PCM_MODE;

    pcmConfig.role = WICED_HAL_PCM_SLAVE;

    pcmConfig.pcm_param.fillData = WICED_HAL_PCM_FILL_0S;

    pcmConfig.pcm_param.frame_type = WICED_HAL_PCM_FRAME_TYPE_SHORT;

    pcmConfig.pcm_param.lsbFirst = WICED_HAL_PCM_MSB_FIRST;

    pcmConfig.pcm_param.rightJustify = WICED_HAL_PCM_DISABLE_RIGHT_JUSTIFY;

    wiced_hal_set_pcm_config (&pcmConfig);

But it seems not enough: SCO was opened successfully but I have not heard audio in BT headset. What have I missed in PCM configuration?

I found one more function for configuration:

wiced_hal_pcm_select_pads - But I have not found any examples of using it.
