Hi Tony, thank you for your suggestion. I managed to access BlueOS, it turns out the SD card was corrupted, so after re-flashing it, everything worked.. Now I’m moving on to the next steps, which is vehicle calibration. On the Motor Config page, I’m trying to test the motors in QGroundControl, but I keep getting this error during the motor test:
“MAV_CMD_DO_MOTOR_TEST command failed.”
Any ideas what could be causing this issue?
Thank you, and we appreciate your guidance.
Hi @Nurul -
Glad you resolved the initial issue.
Before trying to do the motor test, have you verified in BlueOS that the ArduRover firmware has been loaded?
Has the vehicle connected with QGC ok? Can you arm and cause the motors to move with the connected joystick?
You should also make sure that the vehicle setup page is not open at the same time as QGC - I prefer to use BlueOS to do motor tests (with QGC closed) and we will be updating our guides eventually to drop QGC usage all together…
Hi Tony,
Happy New Year, and thank you for your previous guidance. We have successfully resolved the software update and vehicles setup issues.
We are now planning to deploy the BlueBoat for an upcoming mission. As part of our preparation, we conducted initial testing in a swimming pool using Auto mode. However, we keep encountering a warning that states “Prearm failed: compass inconsistency.”
We have attempted to recalibrate the compass several times, but the issue persists. This is a bit puzzling, as all calibrations were completed successfully and the system status indicators are showing green.
Could you please advise if there are any additional steps we might have overlooked, or if you have any suggestions on how to resolve this issue?
Thank you in advance for your support.
Hi @Nurul -
It’s likely the pool you’re testing in has strong magnetic fields, from iron rebar in the walls or strong electrical currents. Pools are generally too small for testing auto mode…
To override the pre-arm checks, simply remove the check next to compass, under autopilot parameters, searching arming.
