What is Dataset in Openthread used for?

[jhc]

Hi,

I am studying openthread, I don't understand what is Dataset in Openthread used for? It is just for backup some network parameters? How could I use the Dataset?

Thank you very much!

Hi,

The readme page for the dataset CLI commands may provide you with some useful details about OpenThread dataset.

Best regards,

Hi, Jørgen

Thanks for reply.

I read that before, but I still can't understand it well, any further descriptions for this Dataset concept?

What is its usage? When to use it?

Thank you very much!

Dataset holds the currently active/operational and pending collection of network parameters, including channel, keys, panid, etc. These are stored in flash and used when a device powers up to attach to a previously connected network. It is also possible for the network leader to advertise changes in network parameters. These will then be stored in a pending dataset and applied at the correct time.

Datasets are used when forming new networks and doing commissioning. In many cases the datasets are handled by the stack, you do not need to handle it manually. For advanced features, you can find relevant functions here.
