Thanks @Chad-Sweet
I am having this issue

How to fix it?

Also, the current tools are supported on python 2.7 only but we are working on update for python 3

@Alex-Kushleyev Do I have calibrate the esc to fly voxl2 based quad?

[Alex Kushleyev]

ESC calibration is required whenever you change motor or propeller or battery voltage. Do you have a custom quadrotor or was it pre-built when you purchased it with VOXL2?

@Alex-Kushleyev I am making a quadcopter with voxl2 and the modalai esc. I am trying to calibrate the esc. I am able to run the script but having this issue while scanning the esc with ftdi cable although I am able to run the motors with voxl2 J18 port.

/voxl-esc/tools$ python voxl-esc-scan.py

Is there any way to calibrate esc using voxl2?
