Bluetooth messages in offChat

Bluetooth messages in the KingFy OffChat package: local text between Androids without mobile data.

The message travels over Bluetooth when devices discover each other. Obstacles and distance reduce success rate.

Installing KingFy and creating an account may need a network; nearby notes, once radios are on, do not.
