GATT Profile Connection Functions.

Function Documentation

wiced_bool_t wiced_bt_gatt_cancel_connect	(	wiced_bt_device_address_t	bd_addr,
		wiced_bool_t	is_direct
	)

Cancel initiating GATT connection.

Parameters

[in]	bd_addr	: Remote device address
[in]	is_direct	: Is direct connection or not

Returns

TRUE : If connection started FALSE : If connection start failure

wiced_bt_gatt_status_t wiced_bt_gatt_disconnect

(

uint16_t

conn_id

)

Close the specified GATT connection.

Result is notified using GATT_CONNECTION_STATUS_EVT of wiced_bt_gatt_cback_t.

Parameters

[in]

conn_id

: GATT connection ID

Returns

wiced_bt_gatt_status_t

wiced_bt_gatt_status_t wiced_bt_gatt_get_device_address	(	uint16_t	conn_id,
		wiced_bt_device_address_t *	p_bdaddr,
		wiced_bt_transport_t *	p_transport,
		wiced_bt_ble_address_type_t *	p_addr_type
	)

API to get the bluetooth device address of the connected gatt conn_id.

Note

: The API cannot be used to get the Bluetooth device address in case the device is disconnected

Parameters

[in]	conn_id	: Connection handle of the gatt bearer
[out]	p_bdaddr	: wiced_bt_device_address_t
[out]	p_transport	wiced_bt_transport_t of the bearer
[out]	p_addr_type	wiced_bt_ble_address_type_t of the bearer. Valid only if device referred by the conn_id is of type BT_TRANSPORT_LE

Returns

wiced_bt_gatt_status_t

wiced_bool_t wiced_bt_gatt_le_connect	(	wiced_bt_device_address_t	bd_addr,
		wiced_bt_ble_address_type_t	bd_addr_type,
		wiced_bt_ble_conn_mode_t	conn_mode,
		wiced_bool_t	is_direct
	)

Open GATT over LE connection to a remote device Result is notified using GATT_CONNECTION_STATUS_EVT of wiced_bt_gatt_cback_t.

Parameters

[in]	bd_addr	: Remote device address
[in]	bd_addr_type	Public or random address
[in]	conn_mode	: connection scan mode
[in]	is_direct	: Is direct connection or not

Returns

TRUE : If connection started FALSE : If connection start failure

NOTE : If is_direct = WICED_FALSE, it will create background connection. Default Background connection type is BTM_BLE_CONN_NONE. Before calling wiced_bt_gatt_le_connect please set background connection type (AUTO) using wiced_bt_ble_set_background_connection_type API

wiced_bool_t wiced_bt_gatt_listen	(	wiced_bool_t	start,
		wiced_bt_device_address_t	bd_addr,
		wiced_bt_ble_address_type_t	type
	)

Start or stop LE advertisement and listen for connection.

Parameters

[in]	start	: TRUE to add device to Filter Accept List / FALSE to remove
[in]	bd_addr	: Device to add/remove from Filter Accept List
[in]	type	: Address type of bd_addr

Returns

TRUE : Success FALSE : Failure

wiced_bt_gatt_status_t wiced_bt_gatt_register

(

wiced_bt_gatt_cback_t *

p_gatt_cback

)

Register an application callback for GATT.

Parameters

[in]

p_gatt_cback

: The GATT notification callback

Returns

wiced_bt_gatt_status_t

wiced_bt_gatt_status_t wiced_bt_gatt_validate_conn_id

(

uint16_t

conn_id

)

API to validate connected gatt conn_id.

Parameters

[in]

conn_id

: Connection handle of the gatt bearer

Returns

wiced_bt_gatt_status_t
