Hi,
I want to use optitrack navigation and lua scripting with Copter-4.1.0.
Reading this page, I understood how to use optitrack navigation with the copter.
First, I tried it with Copter-4.0.7 and I could fly copter manually (joystick) with Altitude_hold and Loiter.
Next, I tried the same method with Copter-4.1.0, but I didn’t get the message , and Altitude_hold didn’t pass the preflight check (Bad GPS).
Are there any additional steps to use optitrack navigation with Copter-4.1.0?
