During the last deployment of the blue-Rov it was not possible to get the control. Qgroundcontrol showed there were problems with the magnetic field. I closed the program and started it again, and the problems were obsolete. Does anyone have similar experiences? ---

Hi! I have had that of two different reasons: 1 Working close to metal, like wrecks, powercables. Solution: be aware of that and do not use auto heading but manual control. 2 Calibration error on ROV at start. Restart of ROV usually solve that, if not Recalibrate.
