Hello guys, few days ago I tested newest firmware 1.03.002 if everything is running smoothly and testing some features (follow me, active track, etc). And when my Mavic was flying near to me, I have noticed triple yellow flashing of the rear led lights:

X X X (in 1 seconds)......then 1 second break... X X X (in 1 seconds)......then 1 second break... After few seconds it started blink green as usual.

I have checked manual but there is no info about tripple yellow. There is only fast yellow blinking. I have noticed this flashing few days ago with the old firmware as well and really dont know what does this mean. There were no warning on the RC or phone, no disconnect... No mention about any error in flight log.

EDIT: Yesteday, I have experienced the same behaviour! During slowing down the Mavic.

Anyone experienced the similar flashing? Thank you!
EDIT 2017/01/18: I was able to film this behaviour HERE:

Looking at your log on hd, you're hitting a lot of tolerances - video cache, altitude, modes not enabled, etc...  Not sure, but mine blinks a random yellow or red in between lots of green flashes.  This will happen in any phase of flight & is very inconsistent.  App will show nothing, of course.  ALL values are very low numbers for sensors, it's hovering, no wind, etc.  Doesn't matter.

Are you certain it isn't red and yellow alternating? It is hard to see the red when it flashes really fast. if it is, then it is telling you to recalibrate your compass....but you should also receive a pop up warning on your Phone/tablet as well....

Hello LukasBlecha, could you please make a short video of the light? I'll help to check it.

It is definitely only triple yellow flashing, not yellow and red.  YELLOW: X X X.... pause.... X X X .... pause.... X X X... Triple flashing is done in one second. There is no info in the app or on RC. Everything is on GPS mode with 15-20 satelites.

DJI Mindy: Unfortunately dont have video of this because my phone is in the controler.

THANK YOU!

On the uploaded healthydrones log it says many times:

        Warning        Large Wind Velocity. Fly with caution.

Could it be that the light blinks due to a warning status? Did you see the wind velocity warning on the app?

CuaC: Of course not. It has nothing to do with wind. On video with triple yellow there was no wind warning.

OK, mine intermittently did this so I did a perfect IMU calibration at a local CNC machine shop.  They had a machine-leveled granite block that I used.  Now no more weird lighting scheme ever on the Mavic and the horizon is always level.  It also seemed to smooth out the Mavic's flight characteristics.

Looks like this thread has gone a little quiet. But I'm posting in case anyone is still interested. I'm getting exactly the same symptoms as LukasBlecha. Doesn't seem to affect flight performance. It does make your cheeks go tight when you are over water though. Happening at really short range too. I'm pretty good at analysing the logs, so I'll keep an eye on it and see if I can narrow it down to a specific piece of flight activity.
