Change DJI NEO parameter
Every time I fly in and out with N or S mode, DJI NEO tends to increase the altitude a little bit, which is very annoying.
Because the default altitude that DJI presets is the position that the sensor can get most accurately, when reaching that altitude, NEO will keep the XYZ position at that point, without deviation.
In my case, I want to fly in and out in narrow, low places without suddenly increasing the altitude when passing through them.
Flying with N and S mode, the altitude is very good, if it is too low, it can drift slightly.
And I tried adjusting "Automatically increase altitude" in Dji Neo's parameters every time there is an obstacle near the drone's belly.
But there will be some disadvantages for beginners,
That is, the drone will not hover in the exact position, only the Z axis is accurate and the XY axis can drift slightly.
But I can control these drifting issues, it doesn't matter.
Flying is very comfortable, no need to worry about flying up or lifting up to touch the ceiling

Share for those who don't know

I have adjusted in DJI NEO's Parameter, turn off the command below and you're done.
g_config.flying_limit.avoid_ground_and_smart_landing_enable (Default: 1, change to: 0 to turn off)
When you reach out to catch, you can still land by hand normally, all functions still work normally, no errors.
If you like it, play it, if you don't like it, just leave it as the manufacturer's default

So fly carefully, within the allowed range!
