motor does not reply

[jfl21]

Hellow!
I tried to control A1 motor with Raspberry Pi 4b(ubuntu 20.04).
But when I ran the "motorctrl", the following information is continuously printed:

"
[WARNING] SerialPort::recv, unblock version, wait time out
[WARNING] motor id=2 does not reply

motor.Pos: 0
motor.Temp: 0
motor.W: 7.06952e-10
motor.T: 7.93298e+34
motor.MError: 1986356271
"

Because I don't know the exact motor id, I tried "motor id = 0, 1, 2, or 0xBB". These situation all showed similar errors and the motor didn't work.
So, I wonder what the problem is and how I can solve it.

Thanks for reply. I have solved the problem. The sequence of line which bought together from the motos is wrong. We adjust the line sequence then the motor works well.
