Quick Deployment Guide

I’ve been going through Decawaves quick deployment guide with the ultimate objective of connecting a DWM1001 via a Pi. It’s been an accurate and good guide thus far but I’ve run into a speed bump at section 4.4 Gateway Configuration. I type the command ls -1 /etc/dwm1001
and then see several configuration scripts displayed, so far so good. When I type in the command sudo vi /etc/dwm1001/dwm1001.conf a blank vi file opens instead of an existing one. Is this correct?
