@marguedas thank you

2020-02-04 04:42:19 -0500 marked best answer how to print ros1 bag data output on ros2

Hi, How can I print the output of ros1.bag file in ros2… while I use below command to play data of ros1 in ros2

ros2 bag play -s rosbag_v2 "path-to-ros.bag-file"

I see it is running/playing but i don't see the data which is to be printed on terminal… while I play the same ros1.bag file in ros1 the output data prints on the terminal… why cant or how can I print this output on the ros2 ??

Kindly answer to my question in a detailed way, as I'am new to this.

Thanks in advance.

Looking forward for the quick reply…
