Hi, I have a problem with my robot. Whenever I try to launch it, I keep getting an error message:

[ERROR] cmd:59 failed crc_check

and sometimes

[ERROR] cmd:49 failed crc_check

Although I can see the roboclawnode in the rqtgraph, but I am unable to send any commands to the motors. I have a Roboclaw ST 2x45A with the correct configuration an ROS 20.04. Can someone please help me identify the problem and suggest a solution?

Best regards.
