no tf data recieved

[sergorl]

I did
rosbag play -l some.bag
and
rostopic echo /left/rslidar_packets showed some data.

But when I launched rviz, it showed NO TF Data.

Also rosrun tf view_frames gives: no tf data recieved

I use ROS-noetic and ubuntu 20.04.

How can I fix it?

We have not tested code on Noetic yet~~

Did you change fixed frame to rslidar like this?

i have the same problem. I have changed the fixed frame to rslidar but still the same.
