Mesh Mode — No Router
When you don't have access to a WiFi router, Mesh Mode allows you to share content directly between two Android devices using BLE (Bluetooth Low Energy) and WiFi Direct P2P. No infrastructure. Same FNX2 encryption as LAN.
Host
Creates the WiFi Direct group (WPA2) and announces its credentials via BLE GATT. Manages the session and can remove devices.
Guest
Receives HOST credentials via BLE, performs ECDH exchange and connects to the P2P network. Content sharing is bidirectional.
How it works step by step
Creates the WiFi Direct group and starts announcing credentials via BLE GATT. The FenixHub device name identifies the announcement.
Detects HOST's BLE announcement and performs ECDH exchange to derive ephemeral session key. Then connects to the WiFi Direct P2P network.
Both devices discover each other's content via NSD/mDNS over the P2P network. Transfers use FNX2 (AES-256-GCM), identical to LAN mode.
DEVICE sends periodic pings to HOST. If it stops responding, the Mesh session closes automatically and credentials expire.
Requires the same passphrase on all devices. It's the group's permanent shared secret.
Uses one-time-use ECDH credentials negotiated on the spot via BLE. No shared passphrase needed — each session generates its own ephemeral keys.
iOS restricts WiFi Direct access for third-party apps and limits BLE in the background. The required combination (BLE GATT + WiFi P2P) is not available outside the Apple ecosystem.
