Function Documentation

void wiced_bt_sco_accept_connection	(	uint16_t	sco_index,
		uint8_t	hci_status,
		wiced_bt_sco_params_t *	p_params
	)

The wiced_sco_lib.a was required to be included before we link this function.

Called to handle (e)SCO connection request event (wiced_bt_sco_connect_request_event).

Parameters

[in]	sco_index	: SCO index
[in]	hci_status	: WICED_BT_SCO_CONNECTION_ACCEPT 0x00 WICED_BT_SCO_CONNECTION_REJECT_RESOURCES 0x0D WICED_BT_SCO_CONNECTION_REJECT_SECURITY 0x0E WICED_BT_SCO_CONNECTION_REJECT_DEVICE 0x0F
[in]	p_params	: Pointer to the SCO parameter structure

wiced_bt_dev_status_t wiced_bt_sco_create_as_acceptor_ex	(	wiced_bt_device_address_t	remote_bda,
		uint16_t *	p_sco_index
	)

Creates a synchronous connection oriented connection as acceptor.

Parameters

[in]	remote_bda	: remote device bd_addr
[out]	p_sco_index	: SCO index returned

Returns: WICED_BT_UNKNOWN_ADDR : Create connection failed, ACL connection is not up or address is invalid WICED_BT_BUSY : Create connection failed, a SCO connection is already conncted to the same BD address WICED_BT_WRONG_MODE : Create connection failed, link in park mode or automatic un-park is not supported WICED_BT_NO_RESOURCES : Create connection failed, max SCO limit has been reached WICED_BT_PENDING : Create connection successfully, "p_sco_index" is returned

wiced_bt_dev_status_t wiced_bt_sco_create_as_initiator	(	wiced_bt_device_address_t	bd_addr,
		uint16_t *	p_sco_index,
		wiced_bt_sco_params_t *	p_params
	)

The wiced_sco_lib.a was required to included before we link this function.

Creates a synchronous connection oriented connection as initiator.

Parameters

[in]	bd_addr	: Peer bd_addr
[in]	p_params	: Pointer to the SCO parameter structure
[out]	p_sco_index	: SCO index returned

Returns: WICED_BT_UNKNOWN_ADDR : Create connection failed, ACL connection is not up WICED_BT_BUSY : Create connection failed, another SCO is being conncted to the same BD address WICED_BT_WRONG_MODE : Create connection failed, wrong mode WICED_BT_NO_RESOURCES : Create connection failed, max SCO limit has been reached WICED_BT_PENDING : Create connection successfully, "p_sco_index" is returned

uint16_t wiced_bt_sco_output_stream	(	uint16_t	sco_index,
		uint8_t *	p_pcmsrc,
		uint16_t	len
	)

The wiced_sco_lib.a was required to include before we link this function.

Send pcm data to internal audio pipe.

Parameters

[in]	sco_index	: SCO index to send the stream
[in]	p_pcmsrc	: Audio stream source.
[in]	len	: Length of stream.

Returns: : Return the legth of non transmited stream.

wiced_bt_dev_status_t wiced_bt_sco_remove ( uint16_t sco_index )

Removes a specific synchronous connection oriented connection.

Parameters

[in] sco_index : SCO index to remove

Returns: WICED_BT_UNKNOWN_ADDR : Remove connection failed, invalid SCO index WICED_BT_NO_RESOURCES : Remove connection failed, no resource WICED_BT_SUCCESS : Remove connection successfully, device is still listening for incoming connection WICED_BT_PENDING : Remove connection successfully

wiced_bt_dev_status_t wiced_bt_sco_setup_voice_path ( wiced_bt_voice_path_setup_t * pData )

The wiced_sco_lib.a was required to include before we link this function.

Configure the SCO routing path.

Parameters

[in] pData : To setup SCO routing path

Returns: WICED_BT_SUCCESS : Config success. WICED_BT_PENDING : Command sent. Waiting for command complete event. WICED_BT_BUSY : Command not sent. Waiting for command complete event for prior command.

void wiced_bt_sco_turn_off_pcm_clock ( void )

The wiced_voice_path.a was required to include before we link this function.

To turn off the PCM/I2S hardware clock This function needs to be called after the application turns off (or mutes audio data in/out of) the codec

Returns: : None

wiced_bt_dev_status_t wiced_bt_sco_write_buffer	(	uint16_t	sco_inx,
		uint8_t *	p_data,
		uint8_t	len
	)

The wiced_sco_lib.a was required to include before we link this function.

This function write SCO data to a specified instance

Parameters

[in]	sco_inx	: sco connection instance
[in]	p_data	: Pointer to data
[in]	len	: Length of data at p_data

Returns: WICED_BT_SUCCESS : data write is successful. WICED_BT_ERROR : generic error WICED_BT_UNKNOWN_ADDR : unknown SCO connection instance.
