Is it possible that two characteristics are notifying at the same time?

[Francis]

I've create a custom service with two characteristics. I need that the values of these characteristics are notifying at the same time. Is it possible? In this case, one of the two characteristics is notifying one time for four times that the other characteristic does it.

If you mean in the same connection interval the answer is yes, but only if you can send more than one packet in a connection interval. What is your central device? I'm not sure what "one of the two characteristics is notifying one time for four times that the other characteristic does it." means. Could you please edit your question and elaborate? Maybe include some code that shows how you are doing this? And how you are testing this?
