Robotis-op2-dxl communication error

Hi, We recovered all motors of robots-op2. Now, we runed firmware update. However it gives a communication error. How can we solve the problem? thanks

Hi @aysegul

Could you elaborate more about “recovered all motors of OP2”?
Did you mean you have performed firmware recovery?
Which software did you use to recover the DYNAMIXEL?

Since you are getting the communication error, you might have recovered DYNAMIXEL with identical ID which will cause communication collision among multiple DYNAMIXEL modules.
