Bluetooth LE
Admiral OS uses Bluetooth Low Energy for out-of-box device setup and, once a device is claimed, for cloud-authorised field service (§4.11). The dashboard's Provision over Bluetooth and Repair over Bluetooth pages implement this protocol in the browser. This page covers the full provisioning protocol — advertising, GATT service and characteristic definitions, the provisioning state machine, security model, error codes, and implementation notes for both firmware and mobile clients.
Sysfs Interface
Admiral exposes a virtual sysfs interface to workload containers at /sys/admiral and low-level platform interfaces on ARM development boards. The architecture bridges the host-level Bluetooth/Network daemon with workload containers, enabling zero-cost, lock-free IPC via read-only bind mounts of standard tmpfs assets.
