→‎Packet Structure: Added link to open source gpsdecode library

*Field 5 - Never observed a packet with this length and subtype that wasn't all FF's

*Field 6 - WAN Address - Oncor uses GPS coordinates, CoServ uses LAN with padding of some kind. The open source [https://github.com/beroset/gpsdecode gpsdecode] library shows one way to translate between WAN Address and GPS coordinates.

*Field 7 - Increments some amount with each transmission and rolls over at 0xFF, always an even hex value
