SimpleBLE for Unreal Engine brings Bluetooth Low Energy workflows into Unreal projects through Blueprint-friendly and C++ APIs.

The plugin is designed for runtime BLE integrations such as companion hardware, IoT devices, sensors, controllers, prototypes, installations, robotics, and other nearby-device workflows.

Use the high-level `USimpleBLEManager` for compact scan, connect, read, write, and notify workflows, or use the lower-level adapter and peripheral objects when you need direct access to services, characteristics, descriptors, manufacturer data, byte arrays, and structured operation results.

Included:

- Runtime `SimpleBLE` code module.

- Blueprint and C++ APIs.

- Adapter discovery and adapter state checks.

- Timed scanning and scan callbacks.

- Peripheral connection and disconnection.

- Service, characteristic, descriptor, and manufacturer data inspection.

- Characteristic read, write request, write command, notify, and indicate.

- Descriptor read and write.

- UTF-8, hex, and byte array conversion helpers.

- Structured operation results and error messages.

- Local documentation for installation, Blueprint usage, C++ usage, platform notes, troubleshooting, and licensing.

- Vendored native SimpleBLE runtime binaries for the supported target platforms.

Supported target platforms:

- Windows 64-bit

- Mac

- iOS

- Android

- Linux

Notes:

- Mobile and desktop Bluetooth permissions still need to be configured in the consuming Unreal project where required by the platform.

- Linux runtime targets need the host BlueZ and D-Bus Bluetooth stack installed and running.

- iOS and macOS projects should include Bluetooth usage text in the app plist.
