missing odom to base tf link - dropped 100% odom messages

edit

I have recorded a bag file using a physical robot with odometry and lidar info.

The robot uses arduino controllers to push data up to a PC using rosserial.

All seems to work correctly until I attempt to create a map with gmapping.

Once I have driven the robot around and saved a XXXXXXX.bag file

I start the core, then use "rosparam set use_sim_time true" , then "rosrun gmapping slam_gmapping", then "rosbag play --clock XXXXXXX.bag" ' I see MessageFilter [target=odom] dropped 100% of the messages so far........and mapsaver waits forever the map.......

rqt_bag shows tf and odom data, raw data shows data in both /odom and /tf, everything looks correct.

when I run rosrun tf_view_frames I only see base_link----> laser_frame and broadcaster /tf info.

However, I expeccted to see /odom---->base_link as well, but this is not the case.

I have included the PC code to convert the arduino serial data to odom/tf messaages.

does anyone has any suggestions ?
