Hi UMnate,
I think advDelay is around 10ms to avoid collisions, so for advertising intervals of 100ms, you can get one ADV, the next one after 102ms, the next one after 109ms, next one after 104ms... and so.
I do not think it is possible to send ADV faster, since I've read other posts complaining if lower values are set, no ADV are transmitted at all.
Good luck!
