Steps to be done

What you have to do to get it running is quite simple.

1. Just add an application e.g. Adeunis Field Test Devices.
2. Register your device
3. Configure the Adeunis with APP EUI and APP Key
4. Copy and paste the payload decoder into Payload Formats

Now you can start mapping. See your results at 

https://ttnmapper.org/colour-radar/

Our first mapping with the Adeunis was at the Hambacher castle in Germany. We did reach our gateway located in Frankfurt in 95 km distance. Great!!
