[marcoag]

Configuration

• Chip set: AMD64
• DDS: CycloneDDS
• Build type: Binary
• OS: Windows

Process

Step 1 - Check record

Actions

You should stop the talker once the recording is stopped.

# StdIn - terminal 1
ros2 run demo_nodes_cpp talker

Run for a few seconds and then hit Ctrl-C to stop the bag recording.

# StdIn - terminal 2
ros2 bag record /chatter -o my-bag

Expected Result

You should see a folder named my-bag in the current directory

Step 2 - Check info

Actions

Continuing from the previous check.

# StdIn - terminal 1
ros2 bag info my-bag

Expected Results

Something like the following

# StdOut - terminal 1
Files:             my-bag_0.mcap
Bag size:          3.0 KiB
Storage id:        mcap

Step 3 - Check play

Actions

Continuing from the previous two checks. Make sure that the talker is stopped.

The -l option loops the bag. You should kill this process eventually with Ctrl-C.

# StdIn - terminal 1
ros2 bag play -l my-bag

# StdIn - terminal 2
ros2 topic echo /chatter

Expected Results

Something like the following.

# StdOut - terminal 2
