I just installed a analogue sonar on my Vtol plane. (tricopter, 2 tilting motors).
Sonar is correctly read by the system when disarmed, I checked this with mission planner on sonar page and under status tab.
Once system is armed, sonar reading is “stuck” between few millivolt. Please find attached parameter files, mission used for testing and file log (shared Gdrive folder)
I also tried the “old” trick of putting an hand under the sonar while in Qhover but nothing.
