After doing some more thinking and reading about this, I think I have a better understanding of the situation. Can anyone confirm that:
1. The current traces in 188.8.131.52 (4-Green) as mentioned in my previous post, are representative of the very short time to transmit the advertising packet. That is, a single packet is transmitted.
2. The other values that I referred to in my original post are all intervals between transmissions.
Am I on the right track?
