DJI matrice 4E unable to obtain control authority

[anilkumarFM]

Hello

I have the below system :

• Drone : DJI Matrice 4E
• Payload: raspberry pi 4B (linux)
• communication: UART

I ran the sample files from the payload sdk and I am able to get telemetry data via UART (e.g yaw rate, attitude e.t.c)

When I try to run the flight control modules ( takeoff landing ) the sample fails at the step of getting control authority ( DjiFlightController_ObtainJoystickCtrlAuthority). see the image.

the drone is set on N mode, and reading operation is functional , can anyone guide me on how to debug this and overcome the problem ?
