No voltage on battery blinking BLUE LED

[Hunter]

Since this can be searched for it is still relevant.

Flashing blue light will occur when trying to connect to GUI, duh the transmitter is supposed to be OFF!
If you cannot connect try downloading the GUI again, works for me............

Edit: remove existing file first.
