Integration of IMU with rosserial

Hi

I am using rosserial_python in order to run a ROS node on arduino.I was able to publish the odometry information from the arduino.Now i am trying to integrate IMU and i am using Adafruit 9-DOF Absolute orientation IMU Fusion Breatout-BNO055 (https://learn.adafruit.com/adafruit-bno055-absolute-orientation-sensor/overview).

I am able to read the data using th libaray (https://github.com/adafruit/Adafruit_BNO055) but when i try to integrate rosserial with the IMU and publish the IMU data as a rosnode i get the following issue 

@AGR:~$ rosrun rosserial_python serial_node.py _port:=/dev/ttyACM1 _baud:=9600
[INFO] [1503942062.205843]: ROS Serial Python Node
[INFO] [1503942062.211847]: Connecting to /dev/ttyACM1 at 9600 baud
[ERROR] [1503942077.316807]: Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino

I am not sure what is the rootcause of this problem.any inputs on this issue is appreciated.

I think you should select the baud rate as 115200. Check if that works.

Hi Alex

I did try with different baud rates but i still get the same error
