I’ve followed the steps mentioned at https://learn.sparkfun.com/tutorials/9dof-razor-imu-m0-hookup-guide in Windows using Arduino IDE and i got absolutely no error during uploding the firmware to the device. I can see the whole sensor values in serial port screen of Arduino IDE. However when i plug the device to my robot and run roslaunch razorimu9dof razor-pub.launch, it waits too much at the “[INFO] [1528713651.584447]: Flushing first 200 IMU entries…” phase and then when i do rostopic echo /imu, it keeps returning 0 value. Another problem is that it updates every second and it is equal to 1 Hz. I should get much more update. What do you guys think related to problem?
