I'm kind of at a loss here:
I am trying to use mavlink on the erlebrain 3 to directly send messages to the flight controller. I want to send attitude control messages, as mavlink should be more reliable than using mavros and usable for autonomous control.
I can't seem to find the serial port connection that is used to connect to the flight controller though. Does anybody have an example as to how to create and pass along such messages? Is there a better way to control the drone autonomosly without gps?
