CM550 & XM540 W270 problem

Hi
I’m going to use two XM motors to create a system that moves along the LED position shown on the camera. I prepared CM-550 and XM540-W270 for that method. Also, I want to send the method of the system directly from the MCU (jetson nano, arduino etc, etc.) to the CM-550 via the UART port, but the transmission packet doesn’t come out. Could you let me know the packet by any chance?

I am still not clear about what you want to send out from the SBC/MCU. If you are trying to send out DXL Packets, you may have to look at Address 20

CM550_ByPass_Port

Usually I use the U2D2 for that job instead of the CM-550.
