What will be the process of this and what will have to be done buy?
And what extra settings in Pixahwak I have more person face
this problem
No need to buy external barometer, downgrade your firmware to 4.0.3 it will work, i am in 4.0.3 and my drone is very stable
The fix is to use the correct firmware → Pixhawk1 for the old/cheap pisxhawk1 clones labeled with 2.4.6 and 2.4.8 (note: there are cheaper better flight controllers now)
If you get the altitude error that prevents arming then set
BARO_OPTIONS,1
I would strongly advise against downgrading firmware since there has been many important fixes.
Upgrade to latest stable if you have not already. All parameters are retained or upgraded.
