uint8_t LlEncrypt	(	uint8_t *	pKey,
		uint8_t *	pData
	)

Encrypt data.

Parameters

pKey	Encryption key.
pData	16 bytes of plain text data.

Returns: Status error code.

Request the LL to encryption a block of data in place.

uint8_t LlGetEncMode	(	uint16_t	handle,
		LlEncMode_t *	pMode
	)

Get encryption mode used in a connection.

Parameters

handle	Connection handle.
pMode	Storage for encryption mode.

Returns: Status error code.

Get the encryption mode used by a connection.

uint8_t LlLtkReqNegReply ( uint16_t handle )

Negative reply to a LTK request.

Parameters

handle Connection handle.

Returns: Status error code.

Requested LTK encryption key not available. This function is only used when operating in slave mode.

uint8_t LlLtkReqReply	(	uint16_t	handle,
		const uint8_t *	pKey
	)

Reply to a LTK request.

Parameters

handle	Connection handle.
pKey	Pointer to new key.

Returns: Status error code.

Provide the requested LTK encryption key. This function is only used when operating in slave mode.

uint8_t LlReadAuthPayloadTimeout	(	uint16_t	handle,
		uint16_t *	pTimeout
	)

Read authenticated payload timeout value.

Parameters

handle	Connection handle.
pTimeout	Pointer to timeout value.

Returns: Status error code.

Read authenticated payload timeout value for the given handle.

uint8_t LlSetEncMode	(	uint16_t	handle,
		const LlEncMode_t *	pMode
	)

Set encryption mode used in a connection.

Parameters

handle	Connection handle.
pMode	New encryption mode.

Returns: Status error code.

Set the encryption mode used by a connection. Must be called before encryption is started or when encryption is paused.

uint8_t LlStartEncryption	(	uint16_t	handle,
		const uint8_t *	pRand,
		uint16_t	diversifier,
		const uint8_t *	pKey
	)

Start encryption.

Parameters

handle	Connection handle.
pRand	Pointer to the random number.
diversifier	Diversifier value.
pKey	Pointer to the encryption key.

Returns: Status error code.

Start or restart link layer encryption on a connection. This function is only used when operating in master role.

uint8_t LlWriteAuthPayloadTimeout	(	uint16_t	handle,
		uint16_t	timeout
	)

Write authenticated payload timeout value.

Parameters

handle	Connection handle.
timeout	New timeout value.

Returns: Status error code.

Write new authenticated payload timeout value for the given handle.
