Does anyone know why you cannot use the barometer built into the pixhawk as the altitude for the optical flow? Is there a difference in altitude measurements between the barometer and a sonar?
Now that 3DR is no longer selling the optical flow sensor. Which is the preferred chinese vendor to buy this from? I am asking this because there are reports that the sensors from some suppliers are not working correctly.

With Copter-3.3 or 3.4-dev?
hmm ok thats bad news... So there is currently no way to use the opto flow sensor...
When I need to add another Sonar the quad gets to bulky and its not worth the effort for just positioning hold function...

Because MS5611 has kilometer-long range and tens of meters' error over time, while sonar has meter level range and centimeter level error.
