Constant red flashes on back arms help.

[ukglyn]

Hi
I have a friend who has the P2V+ & all has been fine. Today we went out to fly together & all was well on setting up, his home point was recorded & he had the quick green flashes. He then went to calibrate his compass, which upon doing he had red lights flashing on the rear arms of his phantom. He moved locations & changed battery & tried again & has exactly the same issues.

Since going home he has done an advanced IMU calibration, but the problem still persists.

Anyone else come across this issue & a solution to it.

Many Thanks

Fast red, like you get when the battery is low & its doing RTH

Yes S1 switch works fine

He can still start the rotors & take off with this problem & as far as we could tell from the short hover at around 5ft in the air behaved normally, just with fast red lights on the back

Yes got the quick green flashes to indicate it, & app was showing 8 sats, he then did the compass dance & problem appeared.

After lots of messing around recalibrating everything it turned out to be something very stupid. It turns out he wears a smart watch that has magnets to hold it to its docking station, this comes very close to the compass while doing the calibration dance. Take watch off & there is no problem at all.

Just another reason not to calibrate the compass if not prompted or required.
