I have used the instructions given in the forum to get rid of the C28 error that was occuring continuously. After, the firmware update and reboot, the robot is displaying C19 error sometimes.
How can I resolve this issue. There is no reason for the C19 error to occur.
Yes, I was getting the Controller Error Code: C28.
So as per the article I updated the firmware to latest version which is > 1.5.1
After reboot the error went away.
However after some time C19 error started appearing intermittently.
I have had to reboot multiple times to make the error go away.
