Registration of node with pre-configured LoRaWAN keys

As for uniqueness:

@arjanvanb

For OTAA, each device needs an Application Identifier (AppEUI), Device Identifier (DevEUI) and secret Application Key (AppKey; not the secret application session key, AppSKey ).

I guess the (combination of) values should be unique though…

We use the AppEUI+DevEUI combination as identifier for a device, so as long as you use different AppEUIs for devices with the same DevEUI, you should be fine for now (but you may encounter problems in v3 if you would use LoRaWAN 1.1 ReJoinRequests)

Things might be different for other networks, so I’d just make sure the AppEUI and DevEUI are unique (and comply to the rules of an EUI-64, so are either purchased or crafted using specific rules). The secret AppKey can be any secure random value.
