Hi, I’m coding to my rosbot and i found a problem that i can’t find info.
When I run this: /opt/husarion/tools/rpi-linux/ros-core2-client /dev/ttyCORE2
[INFO] [1531983966.277007]: ROS Serial Python Node
[INFO] [1531983966.299024]: Connecting to /dev/ttyCORE2 at 500000 baud
[ERROR] [1531983983.412389]: Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino
Until I install some packages it was ok, I try to remove the packages I install but the error persists. The three leds of the rosbot back are blinking, one in red two in green, but I can’t find what it is.
