How to minimize power consumption with Semi-Continous Advertising?

[Dani]

Good morning,

In the application I'm developping with nRF51822 anb S110 SoftDevice, the final peripheral product will be installed in a physical non-accessible place. So, the intention is to set the peripheral advertising at a certain interval in order to find a central and be sleeping between advertising periods. The central will be there occasionally, and I think about this way of working, because any button will be accessble in order to switch on peripheral for advertising. Power consumption is very important for our application.

Would you reccommend any timing for the above scenario in order to reduce power consumption?

Do you have any power consumption stimation according to that scenario? (please, for stimation, consider crystal and main components similar to eval board).

(The way of working I'm proposing seems similar as the way bluetooth works in a smartphone when switching on a car: when bluetooth in the car is switched on, it takes just few seconds for the smartphone to connect. So, I guess the mobile is doing advertising every X seconds, right?)

Regards.

Furthermore: obviously, it will depend on the advertising interval, but is there any reccommendation about the advertising timeout? (i.e., time window for advertising every X time -advertising interval- and enough to connect to a central if it is there). My intention is to implemenent that: 1.- Advertising at a certain interval during a certain period (suitable period?) 2.- Sleep for a certain time 3.- Go to 1.-
