Re: [leshan-dev] Is there a provision in LwM2M spec for the client to initiate information reporting ?
|
Nothing prevents a client, though, to add some params to the URI query
string during registration, i.e. a clietn could add something like
...&factory=true
in order to indicate to the server that it has been reset to factory
defaults. However, this is not "standard" LWM2M so a server would need
to explicitly check for this or at least "forward" this information to
the application layer ...
