-- Author: Maurice Fahn
-- Created: 2017-12-04
--
-- Tested and working with Wireshark Version 2.4.3.
-- This Wireshark Plugin dissects packets of the LIFX LAN Protocol (https://lan.developer.lifx.com/docs/header-description).
-- It attaches to UDP port 56700 (the default port for LIFX lights).
-- Filter for Set/State Packets:
-- (lifx.type & 0x1 or (lifx.type == 102 or lifx.type == 50 or lifx.type == 52 or lifx.type == 58 or lifx.type == 102 or lifx.type == 118 or lifx.type == 122 or lifx.type == 506 or lifx.type == 508 or lifx.type == 702)) and !(lifx.type == 23 or lifx.type == 51 or lifx.type == 101 or lifx.type == 507)
--
-- Filter for Get Packets:
-- !((lifx.type & 0x1 or (lifx.type == 102 or lifx.type == 50 or lifx.type == 52 or lifx.type == 58 or lifx.type == 102 or lifx.type == 118 or lifx.type == 122 or lifx.type == 506 or lifx.type == 508 or lifx.type == 702)) and !(lifx.type == 23 or lifx.type == 51 or lifx.type == 101 or lifx.type == 507))
