Generic Attribute (GATT) Utility Functions.

Function Documentation

wiced_bt_gatt_status_t wiced_bt_util_send_gatt_discover	(	uint16_t	conn_id,
		wiced_bt_gatt_discovery_type_t	type,
		uint16_t	uuid,
		uint16_t	s_handle,
		uint16_t	e_handle
	)

Formats and sends a GATT discover request.

Parameters

[in]	conn_id	: connection identifier.
[in]	type	: GATT discovery type.
[in]	uuid	: UUID of the attribute to search for.
[in]	s_handle	: Start handle.
[in]	e_handle	: Start handle.

Returns

wiced_bt_gatt_status_t

wiced_bt_gatt_status_t wiced_bt_util_send_gatt_read_by_handle	(	uint16_t	conn_id,
		uint16_t	handle
	)

Formats and sends a Read By Handle GATT request.

Parameters

[in]	conn_id	: connection identifier.
[in]	handle	: Attribute handle of the attribute to read.

Returns

wiced_bt_gatt_status_t

wiced_bt_gatt_status_t wiced_bt_util_send_gatt_read_by_type	(	uint16_t	conn_id,
		uint16_t	s_handle,
		uint16_t	e_handle,
		uint16_t	uuid
	)

Formats and sends a Read by Type GATT request.

Parameters

[in]	s_handle	: Start handle
[in]	e_handle	: End handle
[in]	uuid	: UUID of the attribute to read

Returns

wiced_bt_gatt_status_t

wiced_bt_gatt_status_t wiced_bt_util_set_gatt_client_config_descriptor	(	uint16_t	conn_id,
		uint16_t	handle,
		uint16_t	value
	)

Sets the value of the Client Configuration Descriptor.

Parameters

[in]	conn_id	: GATT connection ID
[in]	handle	: Handle of the descriptor to modify
[in]	value	: Value to set

Returns

int wiced_bt_util_uuid_cmp	(	wiced_bt_uuid_t *	p_uuid1,
		wiced_bt_uuid_t *	p_uuid2
	)

Compares two UUIDs.

Note

Can only compare UUIDs of the same length.

Parameters

[out]	p_uuid1	: First UUID
[in]	p_uuid2	: Second UUID

Returns

int 0 if UUID are equal; -1 if error, 1 if UUIDs are different.

		wiced_bt_uuid_t *	p_src
	)

Copies a UUID.

Parameters

[out]	p_dst	: Destination UUID
[in]	p_src	: Source UUID

Returns

int 0 if success, -1 if error
