I bought two Crazyflie 2 copters. The one connects and operates fine to my android device but the other does not connect at all. When I power it up, it spins, self test ok, but when I click 'connect' on my android device it says connected but the green led does not flash as with the other one. After a while it says disconnected again. I did load the latest firmware on both of them. The two blue led's are on, the red is flashing two times per second, but when I click 'connect' on the android the button turns blue (connected) but the green led does not flash.
I did un-pair the device, tried another phone and tried everything but the green led simply does not start flashing. The other one works perfectly every time.
Connection fails
Re: Connection fails
Did you try scanning for the Crazyflie 2 that can't connect in the settings menu?
How did you flash the firmware?
