Device Role. | |
uint8_t | ack_requested: 1 |
ACK requested flag, guarded by ack_lock. | |

ACK expected sequence number, guarded by ack_lock. | |
struct k_sem | ack_lock |
ACK lock, guards ack_* fields. | |
struct k_sem | ctx_lock |
Context lock. | |
IEEE 802.15.4 L2 context.
struct k_sem ieee802154_context::ack_lock |
ACK lock, guards ack_* fields.
uint8_t ieee802154_context::ack_requested |
ACK requested flag, guarded by ack_lock.
uint8_t ieee802154_context::ack_seq |
ACK expected sequence number, guarded by ack_lock.
uint16_t ieee802154_context::channel |
Channel Number.
The RF channel to use for all transmissions and receptions, see section 11.3, table 11-2, phyCurrentChannel. The allowable range of values is PHY dependent as defined in section 10.1.3.
in CPU byte order
uint8_t ieee802154_context::coord_ext_addr[8] |
Coordinator extended address.
see section 8.4.3.1, table 8-94, macCoordExtendedAddress, the address of the coordinator through which the device is associated.
A value of zero indicates that a coordinator extended address is unknown (default).
in little endian
uint16_t ieee802154_context::coord_short_addr |
Coordinator short address.
see section 8.4.3.1, table 8-94, macCoordShortAddress, the short address assigned to the coordinator through which the device is associated.
A value of 0xfffe indicates that the coordinator is only using its extended address. A value of 0xffff indicates that this value is unknown.
in CPU byte order
struct k_sem ieee802154_context::ctx_lock |
Context lock.
This lock guards all mutable context attributes unless otherwise mentioned on attribute level.
uint8_t ieee802154_context::device_role |
Device Role.
See section 6.1: A device may be operating as end device (0), coordinator (1), or PAN coordinator (2). If no device role is explicitly configured then the device will be treated as an end device.
A value of 3 is undefined.
Can be read/set via ieee802154_device_role.
uint8_t ieee802154_context::ext_addr[8] |
Extended Address (in little endian)
The extended address is device specific, usually permanently stored on the device and immutable.
See section 8.4.3.1, table 8-94, macExtendedAddress.
enum net_l2_flags ieee802154_context::flags |
L2 flags.
struct net_linkaddr_storage ieee802154_context::linkaddr |
Link layer address (in big endian)
uint16_t ieee802154_context::pan_id |
PAN ID.
The identifier of the PAN on which the device is operating. If this value is 0xffff, the device is not associated. See section 8.4.3.1, table 8-94, macPanId.
in CPU byte order
struct ieee802154_req_params* ieee802154_context::scan_ctx |
