Hi everyone, its great to be here. Im from uganda and have a phantom 3 proffesional. When i turned it on this morning it gave me an 'IMU' error, when i followed links on how to calibrate this, i noticed that the sensors part was blank and didnt have any figures on the x and y axis. ..Likewise, the options of IMU calibration were inactivity i think owing to this. ..has this happend to any of you? Please advice?
