RE: OpenThread with FDS not persisting data

I think it's up to the user to store the datasets. The otDatasetSetActive only activates a dataset for the thread stack, ie sends a pointer to the dataset structure, and where that structure is stored is up do the user to decide.

I believe the datasets are used to set all the network and stack configurations for a device with a single call. The alternative are singular calls like otLinkSetPanId who will invalidate any active dataset. We do not use otDatasetSetActive in any of our examples btw.
