I am flying a standard Y6 with APM3.2 and the latest firmware (not sure without looking). When using DP2 on my Xperia cellphone it seems to think the units I use to define altitude for waypoints are feet and not m. Setting a waypoint altitude for 4m for example and the Y6 seems to think it is chest height (or thereabouts). I know what 4m looks like and this is NOT 4m. Any ideas as to how I can get the correct units to be recognized?
All units in DroidPlanner are in Meters. If it’s holding alt lower than you expect, the problem is on the copter side or the environment. Try rearming the copter to reset the home alt.
