Slightly different question here, but in the same vein. I have just been using the .tlog files that I have decoded into csvs using mavlogdump.py, but in those files, all my accel and gyro values for SCALED_IMU2 are all 0 for the whole log. This is a consistent problem, across many different BlueROV2 trials. In the mavlink messages html guide, they say scaled IMU2 is for a second 9DOF device. In other blue robotics posts, like this, I’ve seen people use them. I’m just a little confused and would appreciate some clarity on why they are maybe 0 for me, and why don’t we use SCALED_IMU1, for example (which, I know, is not an offered variable in the tlog files atleast)
Just a bit more info: I am getting data in RAW_IMU and ATTITUDE columns. I’ve read on other posts recommendations to not use the RAW_IMU data for any sort of dead reckoning (or the scaled IMU for that matter, but it seems scaled is better for it if you really want to do dead reckoning)?
Could this be fixed by using the dataflash logs instead of the tlogs?
Thanks!
