Hello,

I hope someone can help me. I am currently trying to read Mavlink messages via USB using a Python script (with pymavlink).

So the following setup:
Pixhawk --USB-- Computer (Python Script)

So far everything works fine. However, I don’t see all Mavlink messages in the Mavlink inspector in MissionPlanner or QGroundControl. In the picture you can see the listing.

Unfortunately, even if I request a parameter via the Python code that is not in the list, I can’t get it either.

I am especially concerned about the parameter “HIGHRES_IMU”.

Can someone help me here? Can I reconfigure something so that I can read the parameter?

Thanks in advance.
