Function Documentation

void legattdb_deRegWriteHandleCb ( LEGATTDB_WRITE_CB cb )

Register write callback.

This function de-register a callback set by legattdb_regWriteHandleCb

Parameters

cb	Pointer to the application callback.

UINT16 legattdb_findCharacteristicDescriptor	(	UINT16	char_handle,
		UINT16	descriptor_uuid
	)

Finds Characteristic Descriptor.

This function finds descriptor with specified UUID which belongs to the specific characteristic

Parameters

cb	Pointer to the application callback.

UINT8* legattdb_getAttrPtr ( LEGATTDB_ENTRY_HDR * p )

Get Pointer to Attribute.

This function will return a pointer to the actual attribute skipping over the header.

Parameters

p	Pointer to the entry.

Returns: Pointer to the attribute.

INT32 legattdb_getAttrUUID	(	LEGATTDB_ENTRY_HDR *	h,
		UINT8 *	buf
	)

Copy UUID of an entry to a buffer.

This function will copy UUID of the entry to a buf

Parameters

p	Pointer to the current entry.

Returns: Length of the UUID which can be 2 or 16 bytes.

UINT16 legattdb_getAttrUUID16 ( LEGATTDB_ENTRY_HDR * p )

Get entry handle.

This will return a attribute UUID in the entry. If the attribute uuid is not 2 bytes the function will return invalid uuid 0x00.

Parameters

p	Pointer to the current entry.

Returns: Attribute UUID of the entry.

UINT8* legattdb_getAttrValue ( LEGATTDB_ENTRY_HDR * p )

Get Attribute Value.

This function will return a pointer to the attribute value.

Parameters

p	Pointer to the current entry.

Returns: Pointer to the attribute value.

INT32 legattdb_getAttrValueLen ( LEGATTDB_ENTRY_HDR * p )

Get Attribute Value Length.

This function returns length of the attribute value.

Parameters

p	Pointer to the current entry.

Returns: Length of the attrbute value.

UINT16 legattdb_getAttrValueUUID16 ( LEGATTDB_ENTRY_HDR * p )

Get value UUID.

This is a convenient function. It returns the attribute value in the form of UUID16. Caller need to be sure this is a UUID16. Or else it...

Parameters

p	Pointer to the current entry.

Returns: Value UUID of the entry.

UINT16 legattdb_getHandle ( LEGATTDB_ENTRY_HDR * p )

Get entry handle.

This function returns the attribute handle of this entry.

Parameters

p	Pointer to the current entry.

Returns: Handle of the entry.

INT32 legattdb_getMaxWritableAttrValueLen ( LEGATTDB_ENTRY_HDR * p )

Get Maxmimut Writable Attribute Value Length.

This function return the maximum writable attribute length. If the attribute is not writable, it will return 0.

Parameters

p	Pointer to the current entry.

Returns: Length that can be written to the current entrie's value, or 0 if not writable.

INT32 legattdb_getPerm ( LEGATTDB_ENTRY_HDR * p )

Get Attribute Permissions.

This function will return permission byte of the attribute.

Parameters

p	Pointer to the entry.

Returns: Permission byte.

void legattdb_init ( void )

GATT DB Initi.

This function should be called to initialize the variable.

LEGATTDB_ENTRY_HDR* legattdb_nextEntry ( LEGATTDB_ENTRY_HDR * p )

Get Next database entry.

This function will return a pointer to next entry.

Parameters

p	Pointer to the current entry

Returns: Pointer to the next entry, or NULL if the entry is the last in the database.

INT32 legattdb_regWriteHandleCb ( LEGATTDB_WRITE_CB cb )

Register write callback.

This function register a callback when data is written

Parameters

cb	Pointer to the application callback.

Returns: TRUE if callback was set successully, FALSE if not enough space.

void legattdb_setAttrValueLen	(	LEGATTDB_ENTRY_HDR *	p,
		INT32	len
	)

Set Attribute Value Length.

This function change the length of current attriute length.

Parameters

p	Pointer to the current entry.
len	New length.

INT32 legattdb_uuidIsTheSame	(	INT32	uuidLen_1,
		UINT8 *	uuidPtr_1,
		INT32	uuidLen_2,
		UINT8 *	uuidPtr_2
	)

Compare UUIDs.

This function will compare the UUID of _1 and _2 . It return TRUE if they are the same. if the size of the two uuid are not the same, they will be converted to 128 bit uuid for comparison.

Parameters

uuidLen_1	Length of the first UUID to compare.
uuidPtr_1	Pointer to the first UUID to compare.
uuidLen_2	Length of the second UUID to compare.
uuidPtr_2	Pointer to the second UUID to compare.

Returns: TRUE if UUIDs are the same, FALSE otherwise.

INT32 legattdb_writeAttrValue	(	LEGATTDB_ENTRY_HDR *	p,
		UINT16	offset,
		UINT8 *	val,
		INT32	len,
		UINT32	permFlag
	)

Update Value of the Attribute.

This function will update the writable attribute.

Parameters

p	Pointer to the current entry.
offset	Offset at which data need to be written.
Pointer	to the data to write.
len	Length of the data to write.
pwermFlag	Attribute permissions.

Returns: Length that can be written to the current entrie's value, or 0 if not writable.
