Hi Justin,

We have seen some dependencies between the range and the antenas orientation, would you precise your test procedure and what happens after 10m?

With some extra though: if you are using the ROS implementation and you are blocked at 10m exactly look at this line in the particle filter: https://github.com/bitcraze/lps-ros/blo ... _pf.py#L43

The tuple there is setting the "bonding box" for the position estimate. By default it is 10mx10m.

hi, arnaud:

I have already measure more tag and anchor, about 10m~20m when 6.8Mbps, and if 110kbps, the distance will add to 50~70m.
so we need add tx power or LNA.

and I want to know you how to use the TDOA?
