I have cyw920706 and i need check HFP profile. I use hci_audio_gateway example code and generate sine via MCU and route via I2S to module. Аs far as I know parametrs of PCM auto-sync with PCM_CLK and PCM_FRAME_SYNC, but when i connected bluetooth headset, i'm not hear sound. I was configuring module to I2S slave mode. Have module another parametrs which i can configuring?

Hi xmaxerx_3748251,
According to comments in hci_control_ag.c, can you try setting up SCO link using API wiced_bt_sco_setup_voice_path()?
The configuration you have mentioned seems correct.

Hi xmaxerx_3748251,
By default, the module is configured as I2S master. Can you please check if you have changed the mode to slave in hci_control_ag.c?

Yes i have changed I2S to slave mode, i was called wiced_hal_set_pcm_config(&pcm_config); and
wiced_hal_pcm_config_t pcm_config =
{
.mode = WICED_HAL_I2S_MODE,
.role = WICED_HAL_I2SPCM_SLAVE///
};
