Today let's learn how to calibrate the compass. When our DOBBY compass failure, the purple lights flash, then we need to calibrate the compass; when DOBBY can not be fixed hover in the air ("Gone with the Wind "situation), also need to calibrate the compass. Enter compass calibrationFirst, we must choose in the open field to calibrate the compass.
Open DOBBY pocket UAVDOBBY connection with the phoneEnter Do.Fun interface, click "Settings", select "compass calibration"Select "Start"
Horizontal CalibrationWill first enter horizontal calibration mode, Please put DOBBY Horizontal in your hands
At this time DOBBY indicator should be green light
Please keep DOBBY Horizontal slowly turn 2-3 circles in place
During rotation, keep the green light litObserve indicatorWhen the light changes from green (bottom left) to white light flashes (below right)Horizontal calibration is completeAutomatically enter the vertical calibration mode
Vertical CalibrationAfter entering the vertical calibration modePlease DOBBY machine head downPerpendicular to the ground
At this time the machine indicator change from whiteblinking to white lights long brightIf the indicator still showed white lights flashing, you can adjust the angle slightlyIn the white lights lit stateHolding DOBBY perpendicular to the ground (white light lit)In place slowly rotate 2-3 circles
When white light is off, the magnetic field calibration is completeAPP interface prompts compass calibration is complete Special Attention
Compass calibration we must choose the open space, away from the wire, steel and other interferences;
During compass calibration, please slowly rotated, while paying attention to indicator changes;
When horizontal calibration, please keep the green light lit; vertical calibration, keep white light lit.
