Question about keys and EUI

[Etienne BOURDEAU]

Hello !

I’m new to LoRaWAN, and I can’t get what are the ‘keys’ and ‘eui’ needed to add a node to the gateway, and how to get them.
I want to create a little network of sensors, and make the gateway send the data to a server of my company, without necessarily using TTN or another cloud.

From what I’ve got, Multitech gateway needs 5 keys in hex to add a third party node:

– AppEUI
– DevEUI
– NwkSKey
– AppSKey
and DevAddr, which must be different for every node.

I don’t get what they are used for, and how can I determine them.
Could someone enlighten me ?

Thank you very much !
