This script can arm my quadrotor, but cannot make it take off. Does anyone know why?
My pixhawk is 2.4.6. Firmware is ardu v4.0.4 .
Thanks~
possibility that code may have been edited and resulted in error. Try with code in my repo, it is fully tested.
@pkrana0005 Thanks for your reply.
I found that the biggest difference is baudrate.
Your baudrate is 921600. A lot of website say 57600.
How do you calculate 921600?

Its been a year now since I worked on that, I don't exactly remember why I used that baudrate but generally whatever baudrate is used, it should be same in RPi code and Flight controller, then also communication is possible. The greater the supported baudrate, greater is the speed of communication. So check with all the baudrates.

I mean to say that any change in code may also result in some error or may result in non-working.

I see. I delete vehicle.is_armable in my code. So this change may cause error.
Thanks I will keep trying.
Hello, I used this code but my quadcopter don`t enter in hover mode, only take off and after reached the altitude land
Can somone help me with this problem?

even if you delete that part of the code, i think you won't get through vehicle.armed=True because gps lock is still a requirement.

have u tried increasing the time.sleep part of the code after the take off is completed?
GPS should get locked. Try in open
