Function Documentation

wiced_result_t wiced_bt_dev_deregister_vse_callback ( wiced_bt_dev_vse_callback_t cb )

Application can deregister Vendor-Specific HCI event callback.

Parameters

[in] cb : callback function to deregister

Returns: WICED_SUCCESS WICED_ERROR if the input callback function was not registered yet

uint16_t wiced_bt_dev_get_acl_conn_handle	(	wiced_bt_device_address_t	remote_bda,
		wiced_bt_transport_t	transport
	)

Get the connection handle.

Parameters

[in]	remote_bda	: remote device's address
[in]	transport	: BT_TRANSPORT_BR_EDR or BT_TRANSPORT_LE

Returns: connection handle value 0xffff for invalid

wiced_result_t wiced_bt_dev_get_role	(	wiced_bt_device_address_t	remote_bd_addr,
		uint8_t *	p_role,
		wiced_bt_transport_t	transport
	)

This function is called to get the role of the local device for the ACL connection with the specified remote device.

Parameters

[in]	remote_bd_addr	: BD address of remote device
[in]	transport	: BT_TRANSPORT_BR_EDR or BT_TRANSPORT_LE
[out]	p_role	: Role of the local device

Returns: WICED_BT_UNKNOWN_ADDR if no active link with bd addr specified

wiced_bt_dev_status_t wiced_bt_dev_link_quality_stats	(	wiced_bt_device_address_t	bda,
		wiced_bt_transport_t	transport,
		uint8_t	action,
		wiced_bt_dev_cmpl_cback_t *	p_cback
	)

This API is called to get the statistics for an ACL link.

Limitation This API works when there is only one ACL connection

Parameters

[in]	bda	: bluetooth device address of desired link quality statistics
[in]	transport	: Tranport type LE/BR-EDR
[in]	action	: WICED_CLEAR_LINK_QUALITY_STATS = reset the link quality statistics to 0, WICED_READ_LINK_QUALITY_STATS = read link quality statistics, WICED_READ_THEN_CLEAR_LINK_QUALITY_STATS = read link quality statistics, then clear it
[in]	p_cback	: Result callback (wiced_bt_dev_cmpl_cback_t will be passed to the callback)

Returns

WICED_BT_SUCCESS : If successful
WICED_BT_PENDING : If command succesfully sent down
WICED_BT_BUSY : If already in progress
WICED_BT_NO_RESORCES : If no memory/buffers available to sent down to controller
WICED_BT_UNKNOWN_ADDR : If given BD_ADDRESS is invalid

Note: Callback function argument is a pointer of type wiced_bt_lq_stats_result_t

wiced_result_t wiced_bt_dev_read_tx_power	(	wiced_bt_device_address_t	remote_bda,
		wiced_bt_transport_t	transport,
		wiced_bt_dev_cmpl_cback_t *	p_cback
	)

Read the transmit power for the requested link.

Parameters

[in]	remote_bda	: BD address of connection to read tx power
[in]	transport	: Transport type
[in]	p_cback	: Result callback (wiced_bt_tx_power_result_t will be passed to the callback)

Returns

WICED_BT_PENDING : if command issued to controller.
WICED_BT_NO_RESOURCES : if couldn't allocate memory to issue command
WICED_BT_UNKNOWN_ADDR : if no active link with bd addr specified
WICED_BT_BUSY : if command is already in progress

void wiced_bt_dev_register_hci_trace ( wiced_bt_hci_trace_cback_t * p_cback )

Register to get the hci traces.

Parameters

[in] p_cback : Callback for hci traces

Returns: void

wiced_result_t wiced_bt_dev_register_vse_callback ( wiced_bt_dev_vse_callback_t cb )

Application can register Vendor-Specific HCI event callback.

Parameters

[in] cb : callback function to register

Returns: WICED_SUCCESS WICED_ERROR if out of usage

void wiced_bt_dev_update_hci_trace_mode ( wiced_bool_t enable )

Update the hci trace mode.

Parameters

[in] enable : TRUE to enable HCI traces, FALSE to disable

Returns: void

wiced_result_t wiced_bt_set_local_bdaddr	(	wiced_bt_device_address_t	bd_addr,
		wiced_bt_ble_address_type_t	addr_type
	)

Set Local Bluetooth Device Address.

The application has to set a valid address (Static/Random) by calling this function.
If this function is not called, the default address is typically a controller assigned address(BT device part number), which is same for perticular device type.For example, all CYW43012 devcies will typically have the same default address.

The application can set a static random address by setting the addr_type to BLE_ADDR_RANDOM. For static random addresses the top two bits of the bd_addr are required to be set, the stack will override these bits if not set. The remaining 46 bits will be taken from the value provided for bd_addr,
which cannot be all 0's.

Parameters

[in]	bd_addr	: device address to use
[in]	addr_type	: device address type , should be BLE_ADDR_RANDOM or BLE_ADDR_PUBLIC BLE_ADDR_RANDOM should be only for single LE mode, not for BR-EDR or Dual Mode.

Returns: wiced_result_t

WICED_BT_ILLEGAL_VALUE : if invalid device address specified
WICED_BT_NO_RESOURCES : if couldn't allocate memory to issue command
WICED_BT_SUCCESS : if local bdaddr is set successfully

void wiced_bt_set_pairable_mode	(	uint8_t	allow_pairing,
		uint8_t	connect_only_paired
	)

Enable or disable pairing.

Parameters

[in]	allow_pairing	: (TRUE or FALSE) whether or not the device allows pairing.
[in]	connect_only_paired	: (TRUE or FALSE) whether or not to only allow paired devices to connect. Applicable only for BR/EDR

Returns: void

wiced_result_t wiced_bt_set_tx_power	(	wiced_bt_device_address_t	bd_addr,
		int8_t	power,
		wiced_bt_dev_vendor_specific_command_complete_cback_t *	p_cb
	)

Command to set the tx power on link This command will adjust the transmit power attenuation on a per connection basis.

Parameters

[in]	bd_addr	: peer address
[in]	power	: power value in db
[in]	p_cb	: Result callback (wiced_bt_set_adv_tx_power_result_t will be passed to the callback)

Returns: wiced_result_t
