    BHI160 and BMM150 accuracy definition for SW API what does this mean

    Can someone please explain the meaning of the "accuracy" value given back in the SW API's for most sensor measurements for BHI160 and BMM150. I undertstand the algorithms train themselves to try and minimise errors and maximise accuracy.

    We are currently reseting the whole chip complex and re'initialising between taking measurements. I think this is probably wrong; meaning we would always start  sampling from a low accuracy point. How long does sensor complex have to be running to reach a state of best accuracy?

     

    I have seen a definition was posted here for one of the other sensors.

    Is this defined anywhere for the BHI160 & BMM150?

    Did not like extension .csv; so here as .xls

    We have just made another log using the same system; but this time we logged for aroun 32 minutes.
    Gyros and Accelerometer DO start reporting high accuracy; but this is after about 5 minutes.
