isent anyone else having the sonar alt hold problem???
Just went back to v37 and alt is indicated correctly.
Loaded v39 again ans still the mp shows 137m???
In status field I can see the alt is also 137. Nevertheless alt error shows -0.31 and goes more negative when I lift quad.
In the log sonar shows correct value.
There seems to be something wrong in calculating the correct height.
Do I have to change something in the settings?
Also tested v38, same issue :-(
I experienced the exact same symptoms on both 2.0.38 & 2.0.39. Only difference is, since my Planner is set to feet, it remains frozen at 449ft (same value as yours). For test purposes, same altitude is reported in HK GCS. Have to revert to 2.0.37 or earlier to restore previous functionality.
Pfff, I thought I was the only one.
The hardware and connections weren't changed between version. So that can't be the problem.
I use the latest MP version being 1.0.54
Why does it work with certain persons???
I too had the rolling horizon when connected with USB.
I don't have Xbee on the quad, that is on the plank at the moment.
Was VERY nervous on the first flight of the quad :-)
i hope can setting servo gimbal on ROLL from AMP.
revese and travel adjust servo not work, i just change from arduino :(
Sonar dead allso here. will revert to previous version.
i have set PID for altitude, couse im using 1000kv motor,
but on my 850kv motor sonar work solid.
are you have sonar issue?
