I notice it tends to fluctuate in distance when hovering close to the ground. I even hand held it and raised it above the ground. It'll reach 1.0m and then jump to 3m or 5m. I assume this is normal behaviour? I even cleaned the camera lens to the vps module. I did notice a piece of dust inside the lens. However, I doubt this would cause any issues. If there was issues, it wouldn't read the ground properly at all. Here are the screenshots. Both are when the inspire is grounded. I disabled vps to show the symbol that tells me after 1.0m with vps enabled. I just think the ground needs to be lit well for the vps to work good. Maybe that's my case. After 1.0m the vps is confused on how close it is to the ground. What y'all think? Thanks in advance.
