How to use VL53L0X_CHECKENABLE_RANGE_IGNORE_THRESHOLD

We tried to use VL53L0X_CHECKENABLE_RANGE_IGNORE_THRESHOLD.

But not found any effect on measurement reading.

If you share some input for way to use VL53L0X_CHECKENABLE_RANGE_IGNORE_THRESHOLD, then it will be very useful.

    This theshold says to ignore the range if the signal is so low that it's likely to be a false target.

    The coverglass returns a number of photons. (No glass is 100 percent transmissive.)

    And if those few photons were to trigger a range, you would get a false result.

    So this parameter is generally set to 1.5 times the number of photons the coverglass refects.

    That way you only get a target when there really is one.
