I'm trying to run the script by python2-3 (alias). This is for drone's flight so I'm using dronekit. But I got this error as below. Please help me to solve this error.

• Ubuntu20.04
• Raspberrypi 4 Board

Answer 1

In the terminal output that you posted, there is a Timeout exception at the line which reads vehicle = connect('/dev/ttyAMA0', baud=921600, wait_ready=True) . More details about your setup would be useful, but I'm going to assume you are using a serial radio to communicate with your drone. If that's true, some troubleshooting steps may be:

• Make sure the radio is being mounted to /dev/ttyAMA0.
• Make sure the baud rate for the radio is 921600. If it's something different, pass this value in as the baud parameter in connect .

When asking questions, it's best to give as much detail as possible, and, as the above commenter said, please include code as text instead of linking to screenshots.
