Summary

Description

3rd party dependency updates

Updated container base image to Ubuntu 22.04 LTS version with Python 3.10 (end of life Oct’2026),

Optional support for estimating anchor locations for configuration integrity checks

If enabled, WPE calculates anchor location from a measurement message originating from an anchor node (“opportunistic scan” anchor mode). The anchor location is returned in a separate field, lla_precise_anchor.

Bug Fixes and Known Issues

Bug Fixes

Following table lists the most relevant fixed issues.

Summary

Description

Area deletion does not work correctly if there are multiple networks configured into WPE

Area / zone matching functionality in WPE might get broken in cases where multiple networks are configured for WPE by adding anchors or areas that are linked to different networks. If area deletion is called in such case without specifying the network (as done by WNT), the area management within WPE gets out of sync, causing exception inside WPE.

The issue is fixed by improving the handling of the “global” and network specific areas.

Known Issues

Please see Wirepas Positioning Errata [1] for known issues.
