frame802154_fcf_t Struct Reference

The IEEE 802.15.4 frame has a number of constant/fixed fields that can be counted to make frame construction and max payload calculations easier.

    These include:
    1. FCF                  - 2 bytes       - Fixed
    2. Sequence number      - 1 byte        - Fixed
    3. Addressing fields    - 4 - 20 bytes  - Variable
    4. Aux security header  - 0 - 14 bytes  - Variable
    5. CRC                  - 2 bytes       - Fixed

Defines the bitfields of the frame control field (FCF).
