		uint16_t *	p_clk_tuning
	)

Function wiced_audio_get_jitter_buffer_state.

Debug API to get the jitter buffer state

Parameters

[out]	p_current_buf_ms	: current jitter buffer size in msec
[out]	p_clk_tuning	: current clock tuning value

Returns: None

void wiced_audio_register_play_status_ind_cback ( wiced_audio_play_status_ind_t cback )

Function wiced_audio_register_play_status_ind_cback.

Debug API to register for play status indication

Called by the application before starting the streaming

Parameters

[in] cback : Callback function to be invoked on play status change

Returns: None

wiced_bool_t wiced_audio_set_i2s_out_sf ( uint32_t out_sf )

Function wiced_audio_set_i2s_out_sf.

API to configure output I2S sampling frequency

Called by the application before starting the streaming

Parameters

out_sf Desired output i2s sampling frequency (ex. 16000/32000/44100/48000)

Returns: wiced_bool_t TRUE in success case otherwise FALSE

NOTE : This API must be called before calling the API wiced_audio_sink_configure

wiced_result_t wiced_audio_sink_config_init ( wiced_bt_a2dp_sink_audio_tuning_params_t * p_param )

Wiced audio sink initialization.

Parameters

p_param pointer to the tuning parameters

Returns: wiced_result_t (WICED_BT_XXX)

wiced_result_t wiced_audio_sink_configure	(	uint16_t	handle,
		uint32_t	is_master,
		uint32_t	audio_route,
		uint16_t	cp_type,
		wiced_bt_a2dp_codec_info_t *	p_codec_info
	)

API to configure the sink to perform SBC decoding and to route the decoded audio data over I2S or UART on starting the streaming.

Called by the application when the streaming is to be started

Parameters

handle	AVDT connection handle
audio_route	- Audio route to be used to send the decoded audio data, I2S or UART
cp_type	Content protection type. Refer AVDT_CP_TYPE defined in wiced_bt_avdt.h
p_codec_info	Codec information

Returns: wiced_result_t (WICED_BT_XXX)

wiced_bool_t wiced_audio_sink_decode_in_clk_96MHz_is_enabled ( void )

Check the mechanism to increase CPU clock to 96 MHz whether is enabled.

Returns: wiced_bool_t

void wiced_audio_sink_decode_in_clk_96MHz_set ( wiced_bool_t enable )

Turn on / off the mechanism to increase CPU clock to 96 MHz for decoding audio packet.

Parameters

enable enable / disable the mechanism

wiced_result_t wiced_audio_sink_mute	(	wiced_bool_t	enable,
		uint16_t	ramp_ms
	)

To mute/unmute the audio.

Called by the application to mute the audio when playing the music. Application shall this function to unmute also to restart playing the music

Parameters

enable	1 to mute, 0 to unmute
ramp_ms	ramp up/down time in milli seconds

Returns: wiced_result_t (WICED_BT_XXX)

wiced_result_t wiced_audio_sink_reset ( uint16_t handle )

API to reset the sink on stopping/suspending the streaming.

Called by the application when the streaming is stopped/suspended

Parameters

handle AVDT connection handle

Returns: wiced_result_t (WICED_BT_XXX)

uint8_t wiced_bt_a2d_bits_set ( uint8_t mask )

Function wiced_bt_a2d_bits_set.

Check the number of bits set in a given mask (used to parse stream configuration masks)

Parameters

[in] mask : mask to check

Returns: A2D_SET_ONE_BIT, if one and only one bit is set A2D_SET_ZERO_BIT, if all bits clear A2D_SET_MULTL_BIT, if multiple bits are set

wiced_bt_a2d_status_t wiced_bt_a2d_find_service	(	uint16_t	service_uuid,
		BD_ADDR	bd_addr,
		wiced_bt_a2d_sdp_db_params_t *	p_db,
		wiced_bt_a2d_find_cback *	p_cback
	)

Function wiced_bt_a2d_find_service.

Performs Service Discovery and fetches SRC/SINK SDP Record Info. Information is returned for the first service record found on the server that matches the service UUID.There can only be one outstanding call to wiced_bt_a2d_find_service() at a time; the application must wait for the callback before it makes another call to the function.

Parameters

[in]	service_uuid	: Indicates SRC or SNK.
[in]	bd_addr	: BD address of the peer device.
[in]	p_db	: Pointer to the information to initialize the discovery database.
[in]	p_cback	: Pointer to the wiced_bt_a2d_find_service() callback function.

Returns: wiced_bt_a2d_status_t
