btGetLeEventInfo()

Result btGetLeEventInfo	(	void *	buffer,
		size_t	size,
		BtdrvBleEventType *	type
	)

GetLeEventInfo.

Note

This is identical to btdrvGetLeHidEventInfo except different state is used.

The state used by this is reset after writing the data to output.

Parameters

[in]	buffer	Output buffer. 0x400-bytes from state is written here. See BtdrvLeEventInfo.
[in]	size	Output buffer size.
[out]	type	Output BtdrvBleEventType.

btLeClientDeregisterNotification()

Result btLeClientDeregisterNotification	(	u32	connection_handle,
		bool	is_primary,
		const BtdrvGattId *	serv_id,
		const BtdrvGattId *	char_id
	)

LeClientDeregisterNotification.

Note

This is essentially the same as btdrvUnregisterGattNotification.

Parameters

[in]	connection_handle	ConnectionHandle

		bool	is_primary,
		const BtdrvGattId *	serv_id,
		const BtdrvGattId *	char_id,
		u8	auth_req
	)

LeClientReadCharacteristic.

Note

This is essentially the same as btdrvReadGattCharacteristic.

Parameters

[in]	is_primary	Is a primary service or not
[in]	serv_id	Service GATT ID BtdrvGattId
[in]	char_id	Characteristic GATT ID BtdrvGattId
[in]	auth_req	BtdrvGattAuthReqType

btLeClientReadDescriptor()

Result btLeClientReadDescriptor	(	u32	connection_handle,
		bool	is_primary,
		const BtdrvGattId *	serv_id,
		const BtdrvGattId *	char_id,
		const BtdrvGattId *	desc_id,
		u8	auth_req
	)

LeClientReadDescriptor.

Note

This is essentially the same as btdrvReadGattDescriptor.

Parameters

[in]	connection_handle	ConnectionHandle
[in]	is_primary	Is a primary service or not
[in]	serv_id	Service GATT ID BtdrvGattId
[in]	char_id	Characteristic GATT ID BtdrvGattId
[in]	desc_id	Descriptor GATT ID BtdrvGattId
[in]	auth_req	BtdrvGattAuthReqType

btLeClientRegisterNotification()

Result btLeClientRegisterNotification	(	u32	connection_handle,
		bool	is_primary,
		const BtdrvGattId *	serv_id,
		const BtdrvGattId *	char_id
	)

LeClientRegisterNotification.

Note

This is essentially the same as btdrvRegisterGattNotification.

Parameters

		const BtdrvGattId *	char_id,
		const void *	buffer,
		size_t	size,
		u8	auth_req,
		bool	with_response
	)

LeClientWriteCharacteristic.

Note

This is essentially the same as btdrvWriteGattCharacteristic.

Parameters
