hello, i've tried this tutorial but when i rosrun rosserial_python /dev/ttyACM1 or rosrun rosserial_python _port:=/dev/ttyACM1 (my port is ttyACM1), the result is

[INFO] [WallTime: 1464200241.928070] ROS Serial Python Node
[INFO] [WallTime: 1464200241.933151] Connecting to /dev/ttyACM1 at 9600 baud
[ERROR] [WallTime: 1464200259.039163] Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino

i'm sure that my rosserial is in indigo and i've tried installed again following this tutorial. the result still the same. though, i remember, a few weeks before, i've tried rosserial with HelloWorld and it was successful. so i really wonder why right know i got this kind of error '-' Help Please!!

anyway, i'm using Ubuntu 14.04.1 with ROS Indigo

Hey, please check your baud rate. The default baud rate in the tutorial you mentioned above is 57600. This should be set as default when you start, otherwise specify it during startup:

rosrun rosserial_python _baud:=57600 _port:=/dev/ttyACM0

Hi, I am also facing the same problem but could not fix it even after setting the baud rate. I am working with razor 9dof IMU and was not able to make communication between Arduino and IMU. Can you please help me out in resolving this problem.
