Unable to echo accelerometer data from /crazyflie/imu topic

Hello Community,

I am using hover_vicon.launch to hover the crazyflie using vicon data and I am successfully able to hover it to the desired location. However, when I try to echo the rostopics such as /crazyflie/imu, /crazyflie/battery, and others, I do not get any data.

I have asked this question previously in github here: https://github.com/whoenig/crazyflie_ros/issues/176 but didn't get much help.

Whoenig asked me to set enable_logging to True but after doing that I am not even able to launch the crazyserver. Please help!

Regards,
Kashish Dhal

Hi,

So we are not the ones who are maintaining the ROS package, but it is unfortunate that you are having this problem. Before we can help you and try to recreat your problem, we need more information:
  • Which Operating system are you using and which version?
  • Is the crazyflie updated to the latest firmware?
  • Have you changed anything yourself to the code or the launch file?
  • Are you using a crazyflie 2.0 or 2.1?

Hello ,

I am not able to see the orientation and covariance data in ROS IMU topic. Is it not getting published through radio? Is it disabled in the firmware?
