    I got this error when I connected the robot.

    unallowed connected motor : 4 no dynamixel motor found. make sure that motors are correctly connected and powered on.

    I have the suggested compatible versions, i.e., Niryo One Studio 2.2.1, Niryo Paspberry Pi 3 image 2.2.0, Niryo Stepper frimware on motor 1,2,3,4. My robot was shipped in June 2018; which should confirm it is V1. It was working fine before with v1.x. I just updated all software to v2.2.x and this error occurs. It seems it is not treating motor 4 as a step motor somewhere, but instead dynamixel motor. In Niryo One Studio, it is saying the current version of software as below, which is slightly confusing.
    Current version
    Niryo One Studio : 2.2.1
    Raspberry Pi 3 image : 2.2.0
    ROS : 2.2.0
    Niryo Steppers :
    Stepper Axis 1 : 0.0.0
    Stepper Axis 2 : 0.0.0
    Stepper Axis 3 : 0.0.0

    Can you suggest solutions? Thanks!

    For anyone when ran into this problem, simply restart the robot (more than once might be needed).
