I am trying to build a robot with roverC and UNIT TOF with UIFlow.
When I am trying to start a Motors I am getting I2C-Error 19.
After a reset I am getting " RoverC HAt may not be connected".
Can anybody help me with the problem?

Is the StickC securly fitted and is the rover C power switch set to ON?

Can you show your blocks with us and which port do you connect the TOF unit?
