Wi-Fi Direct on Android with offChat
How offChat uses Wi-Fi Direct on Android when the device exposes the API — no router and no carrier data.
Direct answer
On Android, Wi-Fi Direct creates a Wi-Fi link between phones with no access point. offChat enables this layer only when hardware and the OS expose the API.
It is not café Wi-Fi: no carrier internet in the middle. It is a local radio link between Androids running the same KingFy OffChat module.
Quick checklist
KingFy installed, proximity permissions granted, Wi-Fi on (even without a network), and another nearby Android with offChat active.

Does every Android get Wi-Fi Direct in offChat?
No. Only devices that expose the API. If the option is missing, use Bluetooth or mesh when relays exist.
Do I need a router?
No. Wi-Fi Direct is a direct link. Venue Wi-Fi is irrelevant for this layer.
