Hi,all. I test px4’s code with v1.7.2.And I have found that It reports "Manual control lost"and"Manual control regained"repeatedly.The issue still exits even in the simulation of gazebo.I wonder that if it is a bug? Could it endanger my flight?Thank you. [image]

I am seeing this bug in SITL with gazebo right now as well

I usually get this when the Tx is too close and it’s swamping the Rx. I move the Tx a few feet away and it stops. Good luck.

We see spurious Manual Control Lost events when the CPU on the autopilot gets overloaded. Even if there is a very brief spike in CPU load we will see Manual Control Lost warning. I should add that we don’t actually have a RC TX/RX plugged in, but we have the failsafes disabled. I wonder if your S…

Is this question have been solved? Because I ran into the same issue the Manual control keep lost and regain. Does anyone know the reason?

But curiously, how could the sitl report the same issue?
