I need help plz..

I got error in launch ros for lps_estimator
I typed these line
$ roslaunch bitcraze_lps_estimator dwm_loc_ekf_hover.launch uri:=radio://0/80/250K x:=3 y:=2.3 z:=1.0

but cannnot find crazyflie radio,, with following message.(screenshot attached)
"could not find crazyradio with given devId!"

radio freq is same with cfclient , log show the 0/80/250K.

so
What I am doing wrong?

If the crazyradio is currently connected it might be that you have to add udev rules to allow ROS to use it. See this documentation about setting up the linux udev rules file: https://github.com/bitcraze/crazyflie-l ... ermissions.
