Just got my Nano today and the first thing it wants to do is a firmware upgrade. For some reason I loose pairing halfway through the firmware upgrade. I can shut the aircraft and controller off and back on and there paired again. So far three attempts and three fails. I have not done anything else yet, shoot I haven't even explored the sky app yet like I said I just open this like a hour ago. Don't want to screw it up yet, any advice?
