ObexOS

ObexOS is an open-source operating system designed for embedded and edge devices, with an emphasis on secure, efficient object-exchange capabilities. It centers on the OBEX family of protocols, commonly used for Bluetooth file transfer and related transports, to enable interoperable data exchange in constrained environments.

Designed for small footprints and predictable behavior, ObexOS aims to be modular and portable. The architecture typically features a compact kernel or microkernel core, a dedicated OBEX stack, device drivers, and a user-space application framework that supports lightweight services and tooling.

Key components include a secure OBEX implementation with support for related profiles, an over-the-air update mechanism, and a package manager for modular software. The system emphasizes security through code signing, secure boot, sandboxed apps, and minimal privilege for system services, along with power-management features suitable for battery-powered devices.

Development and licensing are oriented toward openness and collaboration; the project is commonly distributed under permissive licenses to facilitate integration into consumer and industrial devices. Cross-platform development tooling targets architectures such as ARM and RISC-V.

ObexOS is intended for devices that require reliable object-exchange workflows, including wearables, automotive peripherals, and IoT gateways. Its design facilitates deterministic behavior and straightforward integration of OBEX-based data transfers into existing device ecosystems.

Reception in the embedded community highlights its clarity of design and security-first approach, while its smaller ecosystem and OBEX-specific focus can limit adoption compared with broader embedded platforms.
