does anyone know what firmware version airnest works with? I have it installed and have 6.1 firmware on my phantom 3 pro but I am thinking of downgrading to 4.1 cause of complications with the 6.1 firmware version but was hoping airnest would still work with 4.1 firmware? I know you have to have you IOS device to 9.2 just not sure about the firmware version, anyone know?
