I am programming my Create 2 with Arduino Uno. It worked fine a few weeks ago, then I just left it there, charging it about once a week. Now when I try to play with it again, I find that it starts to send weird sensor data.
For example, the value of light bumper data (package ID 45) supposes to be within the range of 0-127. It used to be fine. But now I receive 254 when there is no obstacle in front of the robot. Same issue happens to many different sensor readings.
Can someone help me with this problem?
