Resource Defined by LWM2M

Resource Model

LWM2M defines a resource model. In this resource model, all information can be abstracted and accessed as resources. An object includes resources. An LWM2M Client can have a large amount of resources. Like an object, a resource can have multiple instances.

The following figure shows the relationship among the LWM2M Client, objects, and resources.
