I've never even looked at the function, until now.
I followed the instructions in
and it worked flawlessly for me on a Samsung S6 (Android phone ) running Fly App ver1 .3..... BUT.... in a separate attempt on another S6 running 1.1.3 i.e. a pre
Mini 2 version of the App, the second phone did not respond to the drone and it would not bluetooth pair with the drone.
This prompts the question do you have a Fly App version 1.2 or later installed?
What phone do you have and did you have both bluetooth and wifi switched on?
That said what transfer rates are achievable, I saw a 5Mb/s transfer rate, I couldn't be bothered to let it finish the transfer.
When I put the drone's memory card in a reader attached to one of those phones the transfer rate was MUCH higher, I'd guess it was far faster than 20Mb/s. The video it transferred is 2.25Gb and I think the transfer was done in under a minute.....but .....I wasn't paying that much attention, I was happy enough when I saw the %age clicking up fairly quickly.
This prompts the question why waste drone battery to transfer via radio?
