LPS visualization don't seem to work [SOLVED]

[jeremix]

Hi Bitcraze team.

I successfully follow your instructions about getting started with LPS : https://wiki.bitcraze.io/doc:lps:index
Each anchor is set with the rignt number as anchors.
The crazyflie have new firmware. (but the anchors don't)

I successfully launched the visualization with
roslaunch bitcraze_lps_estimator dwm_loc.launch uri:=radio://0/40/2M
with my good uri
but in RViz the green dot don't move when I tried to move the Crazyflie around the room ? (and no error messages)

Assuming that I can fly with the cfclient where should I look for to see further ?

Any help would be appreciated.
