I am attempting to make use of BMP280 barometer to measure current altitude of my quadcopter.
The problem is that it has a very slow reaction time - after lifting the quad a few meters up, the pressure slowly decreases, and it takes a few seconds for it to stabilize. Also, the pressure on the ground can take a significant amount of time to stabilize.
I am wondering if it supposed to be like that? Is there any way to implement a more or less precise altitude measurement on a quad?
I am not using any libraries, reading measurements using bare I2C according to the data sheet.
