no tf data with crazyflie_demo

[binxxx]

Hi, Wolfgang

I am trying to test the basic function of the crazyflie 2.0 while I do not have a joystick right now. I use the command roslaunch crazyflie_demo teleop_xbox360.launch uri:=radio://0/100/2M to test. Others all function well while the rviz shows that there is error with global status. I guess it's not triggered by not installing joy package and not connecting to a xbox360 gamepad. I don't know what is wrong here. Could you help me about it? Thanks in advance.

Hi, That is normal if you don't use an external motion capture system which would provide some useful transformation. Once you have a Mocap, we use a static broadcaster to provide the missing frame, e.g. https://github.com/whoenig/crazyflie_ros/blob/master/crazyflie_demo/launch/hover_vicon.launch#L40
