ieee802154_config_type

enum ieee802154_config_type

#include <include/net/ieee802154_radio.h>

IEEE802.15.4 driver configuration types.

Enumerator
IEEE802154_CONFIG_AUTO_ACK_FPB	Indicates how radio driver should set Frame Pending bit in ACK responses for Data Requests. If enabled, radio driver should determine whether to set the bit or not based on the information provided with IEEE802154_CONFIG_ACK_FPB config and FPB address matching mode specified. Otherwise, Frame Pending bit should be set to 1(see IEEE Std 802.15.4-2006, 7.2.2.3.1).
IEEE802154_CONFIG_ACK_FPB	Indicates whether to set ACK Frame Pending bit for specific address or not. Disabling the Frame Pending bit with no address provided (NULL pointer) should disable it for all enabled addresses.
IEEE802154_CONFIG_PAN_COORDINATOR	Indicates whether the device is a PAN coordinator.
IEEE802154_CONFIG_PROMISCUOUS	Enable/disable promiscuous mode.
IEEE802154_CONFIG_EVENT_HANDLER	Specifies new radio event handler. Specifying NULL as a handler will disable radio events notification.
IEEE802154_CONFIG_MAC_KEYS	Updates MAC keys and key index for radios supporting transmit security.
IEEE802154_CONFIG_FRAME_COUNTER	Sets the current MAC frame counter value for radios supporting transmit security.
IEEE802154_CONFIG_RX_SLOT	Configure a radio reception slot. This can be used for any scheduler reception, e.g.: Zigbee GP device, CSL, TSCH, etc. In order to configure a CSL receiver the upper layer should combine several configuration options in the following way: Use IEEE802154_CONFIG_ENH_ACK_HEADER_IE once to inform the radio driver of the short and extended addresses of the peer to which it should inject CSL IEs. Use IEEE802154_CONFIG_CSL_RX_TIME periodically, before each use of IEEE802154_CONFIG_CSL_PERIOD setting parameters of the nearest CSL RX window, and before each use of IEEE_CONFIG_RX_SLOT setting parameters of the following (not the nearest one) CSL RX window, to allow the radio driver to calculate the proper CSL Phase to the nearest CSL window to inject in the CSL IEs for both transmitted data and ack frames. Use IEEE802154_CONFIG_CSL_PERIOD on each value change to update the current CSL period value which will be injected in the CSL IEs together with the CSL Phase based on IEEE802154_CONFIG_CSL_RX_TIME. Use IEEE802154_CONFIG_RX_SLOT periodically to schedule the immediate receive window earlier enough before the expected window start time, taking into account possible clock drifts and scheduling uncertainties. This diagram shows the usage of the four options over time: Start CSL Schedule CSL window ENH_ACK_HEADER_IE CSL_RX_TIME (following window) | | | CSL_RX_TIME (nearest window) | RX_SLOT (nearest window) | | | | | | CSL_PERIOD | | | | | | | v v v v v -------------------------------------------------------—[ CSL window ]--—+ ^ | | | +------------------— loop ------—+
IEEE802154_CONFIG_CSL_PERIOD	Configure CSL receiver (Endpoint) period
IEEE802154_CONFIG_CSL_RX_TIME	Configure the next CSL receive window center, in units of microseconds, based on the radio time.
IEEE802154_CONFIG_ENH_ACK_HEADER_IE	Indicates whether to inject IE into ENH ACK Frame for specific address or not. Disabling the ENH ACK with no address provided (NULL pointer) should disable it for all enabled addresses.

Function Documentation

ieee802154_init()

void ieee802154_init

(

struct net_if *

iface

)

#include <include/net/ieee802154_radio.h>

Initialize L2 stack for a given interface.

Parameters

iface

A valid pointer on a network interface

ieee802154_is_ar_flag_set()

static bool ieee802154_is_ar_flag_set ( struct net_buf *  frag )

inlinestatic

#include <include/net/ieee802154_radio.h>

Check if AR flag is set on the frame inside given net_pkt.

Parameters

frag	A valid pointer on a net_buf structure, must not be NULL, and its length should be at least made of 1 byte (ACK frames are the smallest frames on 15.4 and made of 3 bytes, not not counting the FCS part).

Returns

True if AR flag is set, False otherwise

ieee802154_radio_handle_ack()

enum net_verdict ieee802154_radio_handle_ack	(	struct net_if *	iface,
		struct net_pkt *	pkt
	)

#include <include/net/ieee802154_radio.h>

Radio driver ACK handling function that hw drivers should use.

ACK handling requires fast handling and thus such function helps to hook directly the hw drivers to the radio driver.

Parameters

iface	A valid pointer on a network interface that received the packet
pkt	A valid pointer on a packet to check

Returns

NET_OK if it was handled, NET_CONTINUE otherwise
