Did some #bitchat testing earlier. It worked outside with an open line of sight within a range of approximately 90 meters which is ~295 feet...not quite 1 American football field from goal line to goal line. That's clear line of sight though in open air, not living room to living room across a typical residential street through two building shells worth of mass attenuating the Bluetooth signal. I wonder if it will work between across-the-street neighbors.
