Detailed Description

GATT Database Access Functions.

Function Documentation

int wiced_bt_gattdb_get_attribute_uuid	(	wiced_gattdb_entry_t *	p_db_entry,
		uint8_t *	p_uuid
	)

Function wiced_bt_gattdb_get_attribute_uuid.

Parameters

[in]	p_db_entry	: GATT DB atrribute entry
[out]	p_uuid	: pointer to UUID holder. Application should pass the required size of UUID It is recommended to pass uint8_t[16], so that we can avoid overflow in case of 128 bit uuid

Returns

size of the UUID

uint16_t wiced_bt_gattdb_get_attribute_value_uuid16

(

wiced_gattdb_entry_t *

p_db_entry

)

Function wiced_bt_gattdb_get_attribute_value_uuid16.

Utility to get service UUID from GATTDB Primary/Secondary services

Parameters

[in]

p_db_entry

: GATT DB atrribute entry

Returns

16 bit uuid

uint16_t wiced_bt_gattdb_get_charcteristic_descriptor_handle	(	uint16_t	char_handle,
		uint16_t	descriptor_uuid
	)

Function wiced_bt_gattdb_get_charcteristic_descriptor_handle.

Utility to get characteristic descriptor handle value from GATTDB. If characteristic does not have a characteristic descriptor with specified UUID, function will return zero

Parameters

[in]	char_handle	: GATT DB characteristic handle
[in]	descriptor_uuid	: Characteristic descriptor UUID

Returns

characteristic descriptor handle

uint16_t wiced_bt_gattdb_get_handle

(

wiced_gattdb_entry_t *

p_db_entry

)

Function wiced_bt_gattdb_get_handle.

Utility to get attribute handle from GATT DB entry To get next attribute handle, application needs traverse by wiced_bt_gattdb_next_entry

Parameters

[in]

p_db_entry

: GATT DB atrribute entry

Returns

attribute handle

wiced_gattdb_entry_t* wiced_bt_gattdb_next_entry

(

wiced_gattdb_entry_t *

p_db_entry

)

Function wiced_bt_gattdb_next_entry.

Find the next GATT attribute entry in the local GATT database To find the first attribute entry pass the address of the local GATT database as a parameter

Parameters

[in]

p_db_entry

: GATT DB atrribute entry

Returns

pointer to next attribute entry
