Anyone can give the advice to solve the px4 flow bad optic health. I installed the firmware and I also install the laser sensor for distance sensor. I googled it yesterday but I can’t finded it. I also followed some procedure in the diydrone and ardupilot wiki but still don;t know the problem.
Does sensor defect or I am missing someting.
Please help me
Hello, I am also facing with the same problem. Did you find any solution for this?
Hi, did you tried re-installing the pixflow firmware?
I was having the same problem, but I got it resolved after re-installing this image of firmware - px4flow-klt-06Dec2014.zip

Hi there,
I still got the same Problem. If I do connect the pixhawk 2.1 with the LiPo and I put the USB, while booting up the, into the Pixhawk the error doesn´t appear. But if I am starting only with the lipo I do have this failure. Firmware is up to date. I tried to reinstall the Firmware but it says it is not nescessary the Firmware is already on the board.
EDIT: Just saw that the opt m y and x says something but not Zero. Is the Flow Sensor than working fine even if the bad optFlow health appears?
Thanks for helping out!

Hey!
Same problem here. Sometimes I have opt m values, sometimes I don’t…(when I want to do a flying test) 
“EDIT: Just saw that the opt m y and x says something but not Zero. Is the Flow Sensor than working fine even if the bad optFlow health appears?”
Have you tried changing the yaw value to -9000 ?
Do you guys think that this is a power issue?
