Current LwM2M standards require all LwM2M messages to be confirmed. Itron understands that OMA will soon be adding an option to selectively disable message confirmation. Changes to both LwM2M server and LwM2M clients will be needed to deliver non-confirmable messages.
It would be great to see this feature on the C8Y road map once OMA add this option.
Hi Iain, we will look into this once it is supported by leshan.
