I live in Cancun which in itself contributes to issues. I have an Iphone 6 and all my MP software / firmware is up to date. I can sit on my balcony and Waze, Google Maps, GPSTracks, etc. all exactly pinpoint where I am. When I hook my phone to my RC, when on the balcony, I will get a 5 GPS reading but when I am at the beach I will get 14 or more on the iPhone GPS. Yet routinely, when I try to activate HOME POINT ME, I get an error message that reads, "Warning: Mobile Device GPS Signal weak. Its location cannot be acquired." I understand the concept but if these other apps can pinpoint my location why can't DJIGo4? Does anyone have any idea as to the minimum GPS signal strength for HOME POINT ME to function properly? Thanks.
