Hi, I still don't show the drone in gazebo according to your way, have you tried it in gazebo？

I just re-ran the instructions here, and they work for me:
https://github.com/clydemcqueen/tello_ros/tree/dashing
https://github.com/clydemcqueen/tello_ros/tree/dashing/tello_gazebo

Are you seeing any errors? What are they?

Hi, it works after i retry your method, thanks so much, wonderful work!! However,i have a new problem here, when i try ros2 topic pub /drone1/cmd_vel geometry_msgs/Twist "{linear: {x: 0.0, y: 0.0, z: 0.0}, angular: {x: 0.0, y: 0.0, z: 0.2}}" to let the drone fly, it doesn't work. Thanks for your answer.

This works for me:

Terminal 1:

# run the appropriate setup, then:
ros2 launch tello_gazebo simple_launch.py

Terminal 2:

# run the appropriate setup, then:
ros2 service call /drone1/tello_action tello_msgs/TelloAction "{cmd: 'takeoff'}"
ros2 topic pub /drone1/cmd_vel geometry_msgs/Twist "{linear: {x: 0.0, y: 0.0, z: 0.0}, angular: {x: 0.0, y: 0.0, z: 0.2}}"
