Hi @DanielBaekke , we are not supplying any Arduino code in our SDK unfortunately. If you want something in Arduino perhaps you can leverage the work from this forum post would be helpful: Arduino DW3000 library
Our SDK is in C with code examples for a CLI and UCI application. The default CLI application already has the ability to show the distance from 1 “base” to 8 other devices. I just published this tutorial yesterday to show that: Tutorial: How to Use DW3 QM33 SDK for One to Many FiRa Ranging Then the modification you would have to make is to look at the distance and decide if the alarm should turn on.
