Hi. I am building a drone with Betaflight 4 Omnibus.
I installed GPS BN-220.
My GPS reading 'Sea Level' altitude (elevation) and that is about 120m where I live. But all my gps (mobile, Garmin..) shows that altitude, so I know it is correct (if we talking about sea level).
But, main quastion is how to set this 120m to 0m at start ? Is that possible?
Some script for that? How do you solved that?
Also I want to say that my drone is not complited yet and I don't have barometar build in or reciever connected.
