Publishing rate from Jupyter is not correct.

[mhaboali]

Hi,

When I tried to publish string message using Start button with rate = 10, I noticed from the terminal when I ran rostopic hz the frequency was increasing constantly with low increases from 0.1 hz to 9.8 hz.

How can I avoid this issue?

Hi @mhaboali

I just checked this -- indeed there was a small error from using a rospy.sleep(...) instead of using

r = rospy.Rate(X)
r.sleep()

which gives a more accurate timeout.

However, I couldn't see a big deviation as you do. I have a PR to make this function behave better.

Fixed, thanks again for the bug report!
