Not Able to Arm the Drone through MAVLINK Commands

I am using Holybro kakute H7mini Flight Controller and I am able to arm it through RC and able to Fly it , But when I am trying to fly it through mavlink commands even arming also not happening, but mode changing commands and servo commands are able to change, I just want to know is the issue is from flight controller side like parameters, any configurations.

Thank you in advance

There should be a warning when it doesn’t arm? Do you see any warnings? PX4 version?

I am simply getting vehicle did not respond to MAV_CMD_COMPONENT_ARM_DISARM and it is giving error message result 4 which is command is valid but execution has failed, For now I am using PX4 version 1.14 with holybro kakute h7 mini, previously with ardupilot also, I faced the same problem.

There are usually statustext messages telling you why something fails.

yeah that’s where I am getting vehicle did not respond to MAV_CMD_COMPONENT_ARM_DISARM and through RC it is able to arm but from Mavlink commands and through QGC also it is not arming.
