Tarot 680 Hex, Pixhawk, EZ SONAR
I've never had a problem with altitude hold or GPS hold functioning in the past. I added a Botix sonic ragefinder that I have used on an APM frame without issue. Now my hex cannot stay at constant altitude and translates up or down when I am at mid-throttle. I still have altitude control with large throttle moves, but it won't stop when I mid-stick, it sort of just stops trying to change altitude as if it it changes to throttle-hover without reading the baro or sonar. Throttle is calibrated correctly.
If I had enable the SONAR in firmware but the module was disconnected, would my drone be expected to behave this way? I know that the read voltage on the board floats if a sensor isn't connected. Hopefully I can troubleshoot this out of the system tonight or tomorrow morning.
Thanks for your help!
