getPositionError always returns zeroes

[reinzor]

pos = pypozyx.Coordinates()
pozyx.doPositioning(pos, pypozyx.POZYX_2D)
pos_error = pypozyx.PositionError()
pozyx.getPositionError(pos_error)
pos_error.data
[0, 0, 0, 0, 0, 0]

When positioning you can choose between two algorithms:

• UWB-only gives you "raw positions", no filtering is done, this is the best algorithm to assess you anchor setup
• Tracking will use current and historic positioning data and sensor data to build a mathematical model that gives more accurate results when the update rate is higher than 1 Hz. It almost always performs better than UWB-only.

The positioning algorithm is chosen using setPositionAlgorithm, both in Arduino as in Python. More information can be found in the Python docs and the register overview. The Arduino library is updated with the tracking algorithm, but the docs are lagging behind.

The Position Error is only available when using the Tracking algorithm.

I have the same problem. I writing in Python ROS. I am using the tracking modes. Is there any other condition i have to fullfill.
