Wookong Compass/GPS issue

Hi guys

Just tested my first multirotor, DJI F550 with the wookong.
I have a couple of questions.

1. Compass calibration - I can not get the blue light, even though I flick the switch (man-atti-gps) several times. Tried a lot of times now but no luck. Noticed however that when I flick the switch 6-7 times the led stops glowing. If i then continue the calibration, everything looks right (green light after horisontal, then white light vertical)
Anybode excperience this??

2. When I hover in GPS mode, the red lights flashes constantly. What can I check?

Flip the switch 10 times; until the blue light flashes.

Thanks, Sidney

Tried 10times this time as you suggested.
Same thing. LED stops glowing, but I still can get the green led when I rotate...

After flipping the switch 10 times do you have the switch in manual position.?

Maybe it is just a Faulty blue led.
I suppose you could check this if you remove props and then plug up the wkm without your tx on. You should get a blue light to tell you that tx signal is lost.

Great tip Paul!
I'll screw of the propellers and check.
Maybe the blue led is faulty as you say.

When I turn of the TX the LED stops glowing!

Guess the blue led is not working then

Good to hear you found the problem. It wouldn't stop me from flying, but now it's time to get in touch with your dealer for a replacement.

strange....
this is the 2nd LED issue i have seen here today. Is this common?

will DJI plan on selling spare parts in the future?

i know some have damaged the GPS in crashes and it would be nice to be able to purchase replacement parts easily.
