Newbie here, so sorry for this question if it is obvious for some of you. I use my old galaxy S8 phone (no carrier service) as a dedicated device just for my MA. I connect it to the controller and everything has worked fine the first few flights while here at the house. I took a trip to a family members house that lives way out in the country and has no wifi and very poor cell service. When powering up my MA to fly I had a hell of a time trying to connect to the MA, only after I created a hotspot on my normal phone and connected the phone I use for flying to it was I able.to get a connection. Do I have to have a wifi or cell connection in order to connect and fly? I see a lot of videos of footage that are very remote so I assume it is something with my setup. I also realize that I would need a connection of some sort in order for it to show maps, etc. I was just given a tab E and plan on now using that, but curious as to the proper way to setup and connect when flying remotely with no wifi or cell service. Thanks in advance!
