When I power on my Solo and controller I receive a "Magnetic Interference" message on the controller. I moved to several different spots to make sure I was clear of any metal or magnetic objects, but to no avail. I thought maybe it just needed a recalibration at this point, but when I go in to calibrate IMU and calibrate compass it will complete the IMU just fine, but the progress bar for the compass calibration only fills halfway then stops and won't progress any further. It was this way in both the 3DR app and in Solex. Then yesterday I decided to do the upgrade to Open Solo and flashed both the controller and the copter successfully, however the warning that was originally displayed as "Magnetic Interference" has changed to "Compass Calibration" in the new Open Solo firmware. Please, does anyone have any ideas to help??
