Can't arm the Sentinel Drone.

[Emon_dey]

Hi:
I am trying to fly the Sentinel drone for the first time. In the, QGC, it is showing 'Not ready' and in the expansion of the error, I can see two things, 'Horizontal gps error is too high' and 'Obstacle avoidance is not ready'. I tried disabling gps and it shows 'Ready to fly' but the drone is not arming. Another thing I noticed, I don't have a 'voxl-px4.conf' file under /etc/modalai folder. Any direction would be greatly appreciated.

@Emon_dey Can you post the output of ls /etc/modalai? Are you trying to arm in manual mode? There is a parameter named COM_ARM_WO_GPS. Is that set to 1?

@Eric-Katzfey I have uploaded the screenshot with output of ls /etc/modalai command
I was able to arm and fly it in Manual model, the 'COM_ARM_WO_GPS' parameter value is set to 1.
In fact, I want to arm it in Position mode and it still shows a warning of 'Horizontal gps error is too high' and the error 'Obstacle avoidance is not ready'.

@Emon_dey The file voxl-px4.conf is in that screenshot.

Obstacle avoidance is not ready

How is the parameter COM_OBS_AVOID set? Should be zero.

Horizontal gps error is too high

What happens if you set the parameter EKF2_GPS_CHECK to 1?
