slam and rosserial problem

hi

i am trying to build map using my robot and it have the following: 1- arduino mega 2560. 2- mpu 6050 connected to mega. 3- motor and encoder. 4- ROS version is indigo. 5-bud rate is 115200. 6- publish rate in ros is 10hz.

the problem is when i launch rosserial no problem occur ,and when launch the base_controller launch and drive the robot no problem occur, but if i launch the slam this problem will occur:

[WARN] [WallTime: 1469440700.533521] Serial Port read returned short (expected 313 bytes, received 120 instead). [WARN] [WallTime: 1469440700.534025] Serial Port read failure: [INFO] [WallTime: 1469440700.534481] Packet Failed : Failed to read msg data [INFO] [WallTime: 1469440700.534846] msg len is 313 [INFO] [WallTime: 1469440700.600580] Setup publisher on rpm [geometry_msgs/Vector3Stamped] [INFO] [WallTime: 1469440700.629758] Setup publisher on imu_data [sensor_msgs/Imu]

and i try to change the publish rate in hz nothing will solve it i asked this question about 5 time and no one give me answer so please help me with this.

more information i hope it will help to solve the problem: slam launch:
