Typedef Documentation

typedef void( wiced_bt_a2d_find_cback)(wiced_bool_t found, wiced_bt_a2d_service_t *p_service)

A2D Find Service Discovery callback.

Callback for A2D Find Service Discovery Records Registered using wiced_bt_a2d_find_service() The callback function will be executed when service discovery is complete.

Parameters

found	: Record found status
p_service	: Contains result of SDP discovery process

Returns: Status of event handling

Note: This is the callback to notify the result of the SDP discovery process

Function Documentation

uint8_t wiced_bt_a2d_bits_set ( uint8_t mask )

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_BIT

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

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

wiced_bt_a2d_status_t wiced_bt_set_a2dp_connection_priority	(	uint8_t	handle,
		uint8_t	high_priority
	)

Set the A2dp connection as high priority.

Parameters

[in]	handle	: Connection handle
[in]	high_priority	: If "1" set the connection to high priority, "0" if normal priority

Returns: None
