7.4.5 Position the Anchors
7.4.5.1 By using the Auto-Positioning Feature (for up to 4 anchors)
Note 1:
The Auto-Positioning function is a quick setup feature to automatically
determine the anchor locations. Note that this feature may result in a small error in
anchor location, making reported tag locations less accurate. For best results it is
recommended that anchor positions are measured to cm accuracy and manually
entered (see below)
Note 2:
Ensure Line-of-Sight between the anchors during these steps

Re-order the anchors in the list to match their locations in the room:

The 1

Tap “Measure” to start the auto-positioning
PREVIEW
Tap ‘PREVIEW’ to check locations before saving
SET HEIGHTS
Enter heights of the anchors by tapping ‘Z-AXIS’
SAVE

The location of the other anchors are calculated from the initial 3 anchor locations
Errors will propagate through the anchors so the usage is confined to small-scale
systems e.g. up to 4 anchors
Auto-positioning can only be used on the anchors that are within Bluetooth range of
the android device.
