Lightweight M2M Object and Resource Registry

Leshan core library embeds LWM2M core objects definition (Security, Server, Devices ...) but you could add more.
Leshan demos embed almost all object definitions.
See Adding-new-objects wiki page to learn more about that.

• LWM2M registry website
• LWM2M registry GitHub repository

If you find a bug in an object definition OR you want to register a new object, open a new issue at LWM2M registry GitHub repository.
