Unable to add device

Hi, This is a brand new installation of the software and I am a noob on loraserver.io but have loads of other LoRaWAN experience (TTN, Loriot etc).

Am seeing gateway traffic happily, and have added an application and now am trying to add a device to the application buy am getting …

uuid: incorrect UUID length: (code: 3)

What’s up? Am I missing something or have I borked the installation somewhere?

TIA

Have you selected a device-profile?

Ah. No! I see I am going to have to RTFM :frowning:

Thanks!

Pat
