Hi, I'm using BMP388 for altitude calculation in my drone.
But I could not reach the correctness which company mentioned on their datasheet.
I'm using relative altitude for my drone, so first I calculate the ground pressure before launch.
After that, after some minutes flight, if my drone comes back to the original position, the altitude value has big difference with the original value, about 10 meters.
I'm using Arduino BluePill board and BMP388_DEV library which Arduino provides.
And also its output pressure value is not compatible, it vibrates a little and it seems not good.
Please help me to solve this problem.
Thank you.
