duplicate imu timestamps when capturing ros1-bdata:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAA1oAAAHgCAYAAAC8bBykAAAAOnRFWHRTb2Z0d2FyZQBNYXRwbG90bGliIHZlcnNpb24zLjEwLjgsIGh0dHBzOi8vbWF0cGxvdGxpYi5vcmcvwVt1zgAAAAlwSFlags with dv-ros and dvxplorer-micro

[Erik Schlenzka]

Hello,
I'm using the DVXplorer and DVXplorer micro in combination with dv-ros for recording event data in ros1.bag format. I encountered the problem, that the DVXplorer micro produces rosbags with duplicate imu-timestamps.

In the attached plots you can see the time intervall between 2 sequential imu-timestamps over a 20s bag, recorded with the DVXplorer micro (on a raspberry5).:

As you can see everywhere where the graph hits 0, the timestamps are duplicate.
I also tested the same capturing (identical dv-ros node and same computer) with the DVXplorer(normal) and get a bag with nearly constant time intervalls between timestamps, as visible in plot2.:

What could cause this?
Did anyone encounter a similar problem?

I am thankful for any kind of help!
