SmartThings Device SDK: Integrate Your Device Using MQTT Protocol
summary
SmartThings Device SDK lets a Wi‑Fi device connect to SmartThings over MQTT using built‑in MQTT client, JSON payloads and JWT auth, and predefined topics device/event and device/command. Developer Workspace generates an onboarding_config.json and requires a device identity (serial number + public key). SDK targets constrained RTOS, Linux and Tizen with a small memory footprint, exposes simple connection and capability APIs, and maps capabilities (switch, colorControl) to ten‑line handlers. Demo shows a smart lamp entering setup via button press, provisioning Wi‑Fi, and then controllable from the app — it works.
