Obstacle Alert & No Obstacle

[flyfishingdrone]

First time drone pilot for recreation. I just returned from an attempt to launch. I was on a beach flat surface (on top pelican case, launched from before) all clear on flight area, nothing in front of the drone. Takes off fine then constant beeping and alert for obstacle. I have to force land and it continues to do this. I tried another site and same thing. Any help for a beginner? Thanks!

No other error messages - no magnetic interference?
re-calibrate....

None at all for either. I didn’t recalibrate. I’ll try that. Thank you!

Sunny day?
The obstacle alarm gets triggered a lot by reflections. Maybe also try cleaning the sensors?
Failing that, calibrate the sensors (its not imu or compass).

Sand on the sensors?

sun rise or sunset directly into the sensors causes obstacle
