Frequently asked questions
Does Bluetooth work without the internet?
Yes. The Bluetooth radio does not need the carrier for a local link. In offChat, talking without internet over Bluetooth requires the module on the phones involved.
How do I send a message without internet over Bluetooth?
Install KingFy, open offChat, turn Bluetooth on, grant permissions and send the note to a nearby Android with the same module. Without proximity there is no delivery.
Does a Bluetooth app without internet solve long distance?
No. Offline Bluetooth communication is local. For longer hops in the same space, the mesh may help if intermediaries are present — still not another city.
