Feature request: Creation or deletion initiated by a LWM2M server, client notifies its application.

[EduardPon]

We would like to have the possibility to get a notification (callback or subscription) from the mbed-client when a object instance is created or deleted via a LWM2M server. This to inform the application to cope with the (dis)appearance of an instance.

Hi, Can you please elaborate your use case ? Which application needs to be informed about this ? There is already a callback which gets called when object instance is created value_updated( ,

Hello yogpan01,

A typical use case for our project is that we want to assign an application function to handle/process a object instance.

• The relation, 1 object instance is processed by 1 application function.
• Each object ID has a specific application function to do its job.

This way be we can dis/enabled specific features in our device via LWM2M commissioning. So this means when creating an object instance via a LWM2M server, a task is dynamically created to run the corresponding application function. But also visa versa, deleting the instance must kill it to free unused resources.

I'm aware of the value_updated callbacks, but how should this work? I cannot set the callback via the LWM2M server creation proces.
