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

                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 
                  INFO: Device and baud rate are not provided, attempting to autodetect..
                  Scanning for ESC firmware: /dev/ttyUSB0, baud: 250000
                  Scanning for ESC firmware: /dev/ttyUSB0, baud: 2000000
                  Scanning for ESC firmware: /dev/ttyUSB0, baud: 921600

                  Scanning for ESC bootloader: /dev/ttyUSB0, baud: 921600
                  ERROR: No ESC(s) detected, exiting.
                  

                  Is there any way to calibrate esc using voxl2?
