Function Documentation

void ieee802154_prependHeader	(	OpenQueueEntry_t *	msg,
		uint8_t	frameType,
		uint8_t	ielistpresent,
		uint8_t	frameVersion,
		bool	securityEnabled,
		uint8_t	sequenceNumber,
		open_addr_t *	nextHop
	)

Prepend the IEEE802.15.4 MAC header to a (to be transmitted) packet.

Note that we are writing the field from the end of the header to the beginning.

Parameters

[in,out]	msg	The message to append the header to.
[in]	frameType	Type of IEEE802.15.4 frame.
[in]	ielistpresent	Is the IE list present¿
[in]	frameVersion	IEEE802.15.4 frame version.
[in]	securityEnabled	Is security enabled on this frame?
[in]	sequenceNumber	Sequence number of this frame.
[in]	nextHop	Address of the next hop

void ieee802154_retrieveHeader	(	OpenQueueEntry_t *	msg,
		ieee802154_header_iht *	ieee802514_header
	)

Retreieve the IEEE802.15.4 MAC header from a (just received) packet.

Note We are writing the fields from the begnning of the header to the end.

Parameters

[in,out]	msg	The message just received.
[out]	ieee802514_header	The internal header to write the data to.
