Hi,

I am using Herelink, QGroundControl, PX4.

While trying to Arm my quadcopter, I am getting the error “Critical: Arming denied! One or more ESCs are offline”. However all ESCs are making sound when the quadcopter is powered on.

Do you get this when arming with another rc controller?

@Alvin Hey, this issue is resolved. The issue was with wrong connection of ESC to Pixhawk. Thanks Alvin.

I am facing the same trouble. The motor can turn when i test in QGC. I don’t know if that means the connection between pixhawk and ESC is right?
