I am new to LoraWAN and TTN. I have bout some devises and the manufacture provided me with Dev EUI, App EUI and App Key for each products. However, I can’t use them when I want to create and application or register my devices. For instance , the App key can only be generated automatically.
No. click on the pencil (on the left) and you can set it. Also in other places you have the same possibility, and you may also have more than one App EUI.
