BluetoothLink

BluetoothLink turns Unreal into a BLE central. Scan for peripherals, connect, and read, write or subscribe to characteristics - ideal for wearables, controllers, sensors and smart toys..

Start a scan (optionally filtered by service UUID), connect to a discovered peripheral, then read, write or subscribe to its characteristics - the full BLE central workflow as Blueprint events on Android and iOS. UUID normalization expands 16- and 32-bit short UUIDs correctly, hex utilities handle characteristic payloads, and demo content demonstrates the complete flow.

BLE connects games and apps to the physical world: fitness wearables and heart-rate straps driving gameplay, custom controllers and toys-to-life hardware, sensor-driven installations and museum exhibits, and companion-device experiences - all without writing a line of Java, Kotlin or Swift.

BluetoothLink is part of the Alpha XP networking collection for Unreal Engine 4.27-5.0+. Every feature is exposed to both Blueprints and C++, ships with styled HTML documentation, and follows one consistent API style across the whole collection. The plugin is compiled and verified against a clean UE 4.27 project, comes with a utility node pack (hashing, GUIDs, timestamps, tokens, validation), and is maintained under the Alpha XP brand with documentation hosted online.

Key Features:

- BLE scanning with service filters

- Connect and pair with peripherals

- Read/write/notify on characteristics

- UUID normalization and hex utilities

- Android and iOS, with demo content

- Utility node pack: CRC32/MD5/SHA-1 hashing, GUIDs, timestamps, random tokens and hostname validation
