I'm working on Voxl 2 Starling drone and I'm not able to perform arm on manual mode. So,  I did voxl-health-check on the drone indoor and I got error as shown below.
Can you advise how to fix this?

@CJ Looks like you don't have an RC connection for manual flight. Is the transmitter powered on? Is it bound properly to the receiver?

@Eric-Katzfey The RC is bind with the drone and it is able to control the drone.  However, the check shows that there is no connection.  Is the RC not bind correctly?  Furthermore, when I perform takeoff and landing using the mavsdk program, there is an error on Visual Failure. Is the error in voxl-camera-server causes this error? ![offboard takeoff 3.png](https://forum.modalai.com/assets/uploads/files/1694482026732-offboard-takeoff-3.png)
