Bug report / Q&A

PRs for Review

IN CERTAIN CASES, orb_copy(ORB_ID(ruby_data_send),fds[u].fd,&dat); is running so slow as to bring the app to a near-stop… even if no messages are actually coming in. What could cause this?

When I commander takeoff for the x500 gazebo simulation with the latest PX4 main, the drone can’t hold the height at all. It drops in height and then again tries to reach the 2.5 m altitude.

Also, I get this message: ERROR [sensors] Accel #0 fail: TIMEOUT!

what does this mean?

same issue here.
any help?
