Hi,

I see. I don't have equations for this, but I would assume you need to know the scan interval/window of the scanner, or make some assumption on how it behaves, to compare the 2 adverting sets in that case.

Connection success rate is the probability that the central receives one advertisement given a total advertising duration. I assume the rest of the connection procedure will be successful after an advertisement is received. The central is a phone with an app that automatically starts scanning whenever it is not connected. I am looking for some equations to calculate the probability similar to the ones in this paper:

So for set 1, the device starts up, and you need to scan and connect within 20 seconds, if you are not connecting within 20 seconds, you need to wait 80 seconds before you can try again. That's quite a long time.
Set 2, device starts up, if you are not connecting within the 2 seconds, you need to wait 8 seconds before you can try again.

[quote user=""]My primary goal is connection success rate[/quote]

1) What's your definition of "connection success rate"?

2) Is is a human that needs to connect, or is the scanning& connection initiation automated?

Let me correct my terminology for advertising.

Set 1 - Interval=100ms, period=100s, duration=20s

Set 2 - Interval=100ms, period=10s, duration=2s

Set 1 advertises for 20s with 100ms interval every 100s and set 2 advertises for 2s with 100ms interval every 10s. The total advertising packets sent after 100s is equivalent but is it safe to assume the connection success rate is also equivalent?

Hi,

It's the scanner that uses scan interval and window. The advertiser only uses a interval.
