I had a question. I've looked at the card and can't find the specific pattern I've seen the past couple times I flew my drone. The first time I got the pattern was at night, and also the next day. Instead of a solid green or even a flashing green, I'm getting an alternating green and purple flash pattern. Not too fast and not too slow, but it's green, purple, green, purple, green, purple. Any ideas what this means exactly? The drone flies fine, but I was wondering if the pattern meant some problem coming. I have a Q500 4K by the way. Thanks.
