How to use bsx_get_headingaccuracy_rad?

[janakiram]

We call bsx_get_orientdata_euler_rad and bsx_get_headingaccuracy_rad functions.

From the first function we get heading value.     We get heading accuracy in radians from the second function.     Can the heading accuracy from the second function be signed value?    Should we add heading accuracy from second function (after converting it to degrees) to the heading value from first function to get the right heading value?   

API document is not clear.

Please let me know.

Any clarification/help would be appreciated.

BSX_S8 bsx_get_headingaccuracy_rad (BSX_F32 * headingaccrad) returns a floating point value.

This is an estimation of the error in the heading measurement. This means BSXLite estimates the true heading to be anywhere between the value you get from bsx_get_orientdata_euler_rad, plus or minus bsx_get_headingaccuracy_rad.
