If the FXOS8700 is installed at fixed location. i.e. we cannot rotate/tilt the device to let the e-compass to do auto calibration. What is the expectation on the accuracy on the compass heading ?
It is hard to estimate an accuracy in such a case.
The magnetometer requires calibrating not only for its own offset, but also against spurious magnetic fields resulting from any nearby ferromagnetic components on the circuit board.
