While experimenting, and thinking of the same ideas, I have the following remarks.
For hudge network, precision in general does not need to be the same everywhere.
Capacity to ask to a particular anchor to switch to tag then back to anchor is a good idea.
Through this idea, it is possible to have anchor you measure with great precision, then you add anchor to extend the network.
Moreover for demonstration, this enables to have a small part (Bluetouth accessible) configured with auto positioning, then add extra Anchor to extend the region with extra anchors.
Having the possibility to copy past the position on the Androi or ask a tag to keep it’s position when changing to tag, would be great.
Regards.
