I couldn't get the NX1 to trigger anything with the EV+ button either.
you can change the contents of your nx_cs.adj file to say "shell script /mnt/mmc/scripts/EV_MOBILE.sh"
this will run the EV_Mobile.sh script at bootup, when you get the green dots go to settings and configure/connect to wifi or you will not get an ip address to connect to.
