I wanted to use the Picroft Image on my RPi3. I already have it on a MicroSD card and I now want to connect to it headless. I already got it a headless RPi working with the Alexa Voice Service and Raspian Jessie, by adding a wpa_supplicant.conf to the boot directory before the first boot.
I tried the same with the Picroft image but I can’t find it’s IP address with the Fing app for Android (which worked for the Raspian Jessie Image).
Any other things I have to do to get remote connection on the first boot, because won’t be able to establish a direct connection to a desktop with HDMI.
