What does a flashing controller signal mean?

[rabidhyena]

Hi
I noticed I frequently get a flashing controller signal (slow flash) despite there being 3 or 4 bars of signal.
What does this mean? and what should I do?
Thanks

This is indicating WiFi interference.
To be on the safe side, move with the controller to a different location (possibly auto scan the WiFi frequencies)

Thanks very much

If yours is like mine, the flashing won't stop until you restart the MP... or the HD signal starts to blink. I've never seen both blinking at the same time, and I've never seen them stop blinking on their own (unless the other preempts it).

I had them both blinking at also stopping doing this while flying off a hotel balcony in Tokyo. No issue to the flight itself.

Mine usually stops if I restart Go 4.

What restarting? Just check here in case of interference and try to choose a channel that is less used
