Running helloworld.py on Solo gives exception, but runs fine locally #286

DarylWM commented 8 years ago

Wondering if anybody has come across this exception when running helloworld.py on Solo? The script finishes, but raises the exception on shutdown. The script runs fine locally.

Does this prevent connection on running the script again? I am getting sporadic connection between the python script running on solo, and the vehicle. A typical error is: File "/home/root/opt/my_python_code/env/lib/python2.7/site-packages/dronekit/init.py", line 2142, in wait_ready timeout) dronekit.APIException: wait_ready experienced a timeout after 30 seconds.

I am struggling with the same issue. Any proposed workaround for the time being?

Did anyone find a solution to this issue? I'm seeing it with my own scripts running onboard Solo.
