DEV EUI not accepted

Hi,
I’m using the Dragino LoRa shield and in TTN this device is running well. Data is sent to my gateway and to the TTN. But when I try to add that device DevEUI in Cayenne, I get a red box around the DevEUI number without an error message.
I’m not using LPP but have my own function decoder build.
what am I doing wrong…?

can you share a screenshot of the error you are getting? You can PM me if you don’t want to share the DevEUI publically.

I have uploaded the screenshot. As you can see there is a red box around the DevEUI

can you remove the spaces in between.

Oh, oh… so simple :wink: Thanks!

The default is Cayenne LPP, but I build my own decoder. How can I set Cayenne in a way that it uses my decoder? Or have I open a new treat for that question…
