@imuguruza Thank you for your response. I have now been able to interprete the IMU readings on the
What version of IMU does erlebrain3 use?
I decided to switch to the IMU because the compass heading reading was not stable enough for my application.
I realized that the IMU data are published on two topics:
/mavros/imu/data : this seems to have similar stability with
/mavros/global_position/compass_hdg. Is it possible that compass reading and IMU data are integrated and published on this topic?
/mavros/imu/data_raw: I assume that this is actual IMU readings from the sensor. However, the orientation published on this topic is 0 on x, y and z axes. Thus, no matter how I rotate the brain, these values do not change from 0 at any time. Is this the expected behaviour?
