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
