    No signal and red dot blinking battery when turn off

    Hi all, Yesterday I flew with 1 of my 3 batteries, doing photos and footage and no problem, when the 1st battery went down I just landed and changed the battery, and when I turned on RC and P3 DJI app was telling me "no signal". I turned off the battery and it show red dot blinking. Any idea...
