Connecting and Managing Zephyr Devices Remotely Using LWM2M and Eclipse Leshan
summary
Shows how Zephyr’s built‑in LWM2M client pairs with Eclipse Leshan to build an end‑to‑end device management stack, detailing bootstrap, registration, the numeric object model, observation versus device‑initiated send, and firmware update sequencing. Explains UDP versus TCP tradeoffs and memory cost of object instances, reports that Leshan is used in production deployments scaling to over one million devices, and demonstrates configuring Zephyr objects with the Zephyr LWM2M client and running a Java Leshan server.
