changeID does not work

[xinsongyan]

I have tried to use the changeID.cpp file to update the actuator ID, but failed.

I tried main branch and A1B1 branch, only A1B1 branch works with the actuator.

After I run changeID,

sudo ./changeID
Please input the name of serial port.(e.g. Linux:/dev/ttyUSB0, Windows:\\.\COM3)
/dev/ttyUSB0
The serial port is /dev/ttyUSB0
The motor ID is: BB
*********open serial************
Please turn the motor.
One time: id=0; Two times: id=1, Three times: id=2
ID can only be 0, 1, 2
Once finished, press 'a'

what does 'turn the motor' mean? the motor feels like in damped mode.
After this, I tried to run the motorctrl, the ID stays the same.
