3 anchors and 1 tag using DWM1000 module and Nucleo board

Hello everyone,
I am working on the Decawave DWM1000 module for some time. And I have obtained good accuracy in the one-direction location tracking. Now I want to work on the two-direction location tracking for that I have to work on multiple anchors. Also I have not user manual of DWM1000 if anyone have that kindly attech it with the reply.

If anyone has any reference about this please reply on this topic.

Thank you
Jainam.
