Getting error while Arming: One or more ESCs are offline


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.
