DEV EUI not accepted

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…
