For: Message type = 00001b, Message Version = 000b, Battery Status = 1200
A device wakes up and, after scouting, it finds 3 access points (addresses “02:01:01:01:01:01”,
“03:02:02:02:02:02”, “04:03:03:03:03:03”) with RSSIs (-85, -90, -110).
“03:02:02:02:02:02”, “04:03:03:03:03:03”) with RSSIs (-85, -90, -110).
