Spanda

Wearables

Wearables are device-tree nodes registered in the device pool with provider-backed telemetry. Spanda does not embed wearable vendor SDKs in core — optional packages bridge to platform APIs (HealthKit, Wear OS, industrial BLE vests, etc.).

Device tree declaration

[[fleet.wearables]]
id = "vest-001"
type = "SmartVest"
provider = "spanda-industrial-wearables"
human_id = "operator-001"
capabilities = ["fall_detection", "proximity_alert", "battery_level"]
protocol = "ble"
endpoint = "ble://AA:BB:CC:DD:EE:01"
trust_level = "verified"

Flat registry ([[devices]]) is also supported with human_id binding.

Discovery

Wearables are discovered through existing discovery transports:

• BLE — spanda-discovery-ble + spanda-ble
• Wi-Fi — spanda-discovery-wifi
• USB — body cams, EEG dongles via spanda-discovery-usb

spanda device discover --transport ble
spanda control-center devices discover --transport ble

Discovered wearables ingest into the device pool with type = Wearable and optional human_id assignment.

Readiness integration

Wearable dimensions in human readiness profiles:

Dimension	Source
Connectivity	Last telemetry timestamp
Battery	battery_level capability
Sensor health	Provider health check
Assignment	human_id matches mission operator

Optional health dimensions (heart rate, fatigue, stress) require SPANDA_HUMAN_HEALTH_ENABLED=1 — see human-readiness.md.

Reference packages

Package	Devices	Status
spanda-smartwatch	Smart watches	Planned
spanda-industrial-wearables	Vests, helmets, gas tags	Planned
spanda-bodycam	Body cameras	Planned
