nRF52832 Advertising Interval

John

I've been puzzled after looking at the current draw figures for the nRF52832. If the advertising interval is supposed to be 20ms.

Can someone explain why the advertising event is actually 25ms?

Or why the advertisng is added to the interval?

    No I understand the "jitter" that you refer to. We have been working with TI and their timing is slightly different...not that it really matters. I'm just curious.

    What they do is set the interval say 100ms, advertise at the start of the interval and deduct the time of the advertisement approx 4ms from the 100ms to calculate the sleep current which is then added to the total current over 100ms. What Nordic do is actually add the time of the event to the advertising interval so 100ms becomes 105ms. Just different..no problem working with it....I'm wondering if strictly speaking it conforms to the iBeacon specification with this very slightly different timing.
