Could not run arm_test.py

[Kido]

I’m currently trying to complete the precision landing course.

I’m trying to run arm_test.py but it says dronekit has no heartbeat.

My hardware is Cube Orange + Raspberry Pi 4 and they are connected via USB CP2102 FTDI, hence I had to modify the connect code to
vehicle = connect(’/dev/ttyUSB0’,baud=921600,wait_ready=True)

I tried running mavproxy.py --master /dev/ttyUSB0 and it works just fine which makes me even more confused.

Any help would be greatly appriecated

Not sure. What if you change this statement to :

vehicle = connect(’/dev/ttyUSB0’,wait_ready=True)
