    I also unable to calibrate other sensors using the App. Always get the sensor heating message. Only compass can be calibrated. Is the control problem only happen on GPS mode? Can you try is manual mode also has control problem?

    If you celibate the compass with the app the compass calibration will be wrong. It cannot be done by an app as it is too close to interferences sources.

    This is a peace of stupid software.

    Cheers

    Hey man, my situation was exactly like you, the same symptoms.
    I've tested all the possible solutions listed here, but anything worked.
    I download the windows software Walkera Assistance and updated de firmware of the aircraft.
    I was able to complete the compass calibration process whith the Walkera Assistance software.

    I think TX means transmitter which should be the controller. Radio frequency device can affect the compass if too close.

    Did you check the sensor status on the Apps? When put the aircraft on flat ground is the status bar of sensors are green? If show yellow or red means the sensor has problem. Is any sensor show red status other than the compass?

    It's important if you want to use the GPS return to home function. The aircraft may fly to wrong direction if compass not calibrate.

    The FC should only need calibration once. It does calibrate on its own if you fly it often enough on Manual.

    If the App says no need to calibrate after many flights then don't.

    Cheers

    I have trouble working with the HT compass sensor. I already use Xanders calibration code to calibrate it. But still it gives biased readings. Then I write a few testing programs and find that: in the relative mode, the negative 180 degrees 0-180 covers more than a half circle than the positive degrees, i.e. some degrees are distributed more intensively. Does anyone have ideas about the possible causes?
