I can 100% confirm the dual blutooth gps addon for non gps tablets works with the Phantom Follow me feature. Works very well indeed. I have the non cellular ipad mini 2, but the dual gps works and have had my Phantom 3 follow me with my non gps ipad 2.
What you got to do is pair it with blutooth and have the dual gps app running in the background, so pair it on your tablet, run the dual app, when you see it has satelite connection, leave the app running, start the dji go pilot and then follow me will work 100%.
If you don't have the dual app running in the background follow me won't work with the dual gps. It must be run and left running in the background for it to work.
