Re: [leshan-dev] Should Leshan just be used for management or data colle

[Simon Bernard <contact@xxxxxxxxxxxxxxx>]

Registration is a kind of session object, I suppose you don't want to 
store you data in this session object.

About persisting device data, you should just use the send API of 
LeshanServer, get the response and then store it as you want.
You will probably store the data by "device endpoint" and you will 
probably don't want to delete data when device deregister. This would be 
like if you delete all user data of web app when user logout.
